Realtek HDMI Output ATI HDMI Audio - Not Plugged In

Oct 28, 2012

I'm trying to hook up my TV with my computer, and for the most part it's working. The video goes through and I get how to control it and everything. The only thing not working is the sound.

I'm using an HDMI to HDMI cable, and like I said the video is fine. Also, when the cable is plugged into my boyfriend's laptop, the sound comes out of the TV.

So this must mean the problem is with my computer specifically. Although, this computer is only a month old, so I wouldn't think anything is out of date.

Have Realtek High Definition Sound But No Hdmi Output

Nov 20, 2009

I've upgraded from vista to 7 and I am getting no sound, I've searched, searched and tried alot of different things, I see alot of people on this forum with the same issues, but I've tried most of them. I've installed and unistalled all the different drivers from realtek, but no luck. I have realtek high definition sound but no hdmi output. In my device manager it says the sound driver is installed properly, but when I tried to test the sound it fails to test tone, I don't know if it has to deal with an audio codec. I have regular speaker that connect to a sound jack. At this point I am quite desperate. I've spent all night trying to figure this out.

HDMI Audio Output - How To Get It To Work

May 1, 2012

I only have this problem with 7, so I know it is not a hardware related issue. I simply can not get any sound out of my graphics card (seemingly) through HDMI. I have my bios setup to play audio from it. I've followed what everyone else has done when using the search, I have zero success. It worked before using 7, so I am 100% confident that this is a 7 issue (because it still works on Ubuntu!).All drivers and software is up to date too.

Mobo: M3a79T Deluxe
CPU: Phenom II X6 1090T
GFX: GTX 275

Split Audio To Two Separate Output Devices: HDMI & Desktop Speakers?

Apr 3, 2012

splitting audio to two separate output devices in windows 7 x64.I'm preparing my primary PC to act as a Media center. Ideally I'd like for someone to be able to watch netflix, or online videos on the TV with audio and video running through the HDMI cable while someone else can use the PC monitor & desktop speakers to game or do other tasks. The issue is both gaming applications and chrome (or other web browsers) only support audio playing through the default audio device in windows 7. As a result, i'm forced to pick whether i want all audio to play from the TV speakers or the desktop speakers.

Summary of Specs:

Asus M2N-Sli Deluxe mobo - rear port used for desktop speakers
Radeon HD 6870 - HDMI for TV sound
Athlon 64 x2 6000+
4 gigs ram

Doing some research I've learned this was a feature in win XP but was dropped in vista/7. On windows 7 support forums the Microsoft Support reply that it was an intentional omission win both windows 7 and vista.I know how to direct the audio from winamp, media player classic, and WMP to the output device of my choosing.I have tried three third party applications:Virtual Audio Cable: lets me play the same audio out both the HDMI connection and the desktop speakers.IndieVolume: shows promise as it lets me direct audio from applications to the output device i choose, but all attempts to get the software to change my web browser's output device haven't worked. I also think the software is not supported for windows 7 x64.J River - Media Center 17: media center software with an embedded web browser. Using this media center i can direct the audio from any media on my computer to the audio device of my choosing, but the embedded web browser plays out of windows default output device not the audio device i choose.

Sony Vaio Laptop Audio Output HDMI Not Working In Samsung Monitor T23A750

Dec 24, 2011

I've recently purchased a Samsung T23A750 monitor and to my disappointment when I try to watch a movie the built in speakers are not functioning. I have a Sony Vaio Z216GX connected via HDMI to the monitor (HDMI-DVI) port. I can definitely see the video, but no audio is playing from the speakers. The built in speakers are not at fault- I did a self-diagnosis of the monitor and the speakers seem to work fine. I also set the monitor as the default for the audio and even when Win 7 says its functioning properly, the speakers still don't work. Conversely, setting the default to my PC speakers work fine. I'm sure its not the HDMI cable- I used the same one to hook my pc to my tv with everything working fine.

Nvidia HDMI "not Plugged In" (greyed Out), Video, But No Audio?

Sep 13, 2012

Here's my setup: Nvidia video card>HDMI out to Sony Home Theater System>HDMI out to Samsung HDTV. I use this to get 5.1 LPCM surround sound for video games. It worked fine until I did a firmware update on the Sony unit. Now, the HDMI audio is greyed out in Windows 7 audio playback options. Nvidia Control Panel sees the device as audio compatible, but Windows does not.Audio DOES work if I connect a different display (through the same system). I connected an Acer computer monitor and everything worked normally. It also works it I connect it directly to the Samsung TV. The Sony unit works on its own or with the Acer monitor connected. When the monitor is connected, Nvidia Control Panel sees the home theater system as Sony AV System and Audio Playback reports SonyAVSYSTEM. When the Samsung TV is plugged in, Nvidia CP sees the home theater system as Sony Digital Display and Windows audio just says the cable is unplugged (doesn't report anything). I'm getting picture with this setup, but I can't even select the audio option.

I'm going crazy at this point, I have Sony working on it from their end and Samsung insists it's not their fault. Is this a Windows problem? I find it strange that Nvidia CP can recognize the unit and marks it as audio-capable, but Windows says a cable is unplugged. I've tried all recent driver options for both Realtek and Nvidia (Betas and stable). All drivers work the same under different connections described above. That the system works normally unless PC>Theater>TV makes me think that this is a pretty specific breakdown in communication with HDMI!date:Sony representatives got back to me with the findings from their engineers. They insist that because my PS3 works on the setup, it must be an issue with my PC. Their best guess is that the devices are failing to handshake properly over the HDMI connection.

i've twice installed latest drivers GeForce 285.62 Driver , i've been into nvidia control panel and then setup multiple monitors & it only detects my other vga monitor not the hdmi one, i'm using a brand new hdmi cable & can confirm i've connected it to the correct hdmi connector on my monitor, it has 2 hdmi ports and i've tried both, when i go into device manager & display adapters there is only 1 adapter that says nvidia geforce gt 545, should there be another 1 for the hdmi? i'm out of options, i even work in i.t as a breakfix engineer coming across similar issues like this but i cannot deal with this & really need some help so i'm really hoping someone will help me out here i'm wondering if its anything to do with my other hardware such as the xeon cpu? (a longshot but i've only just built this pc & never built a xeon system before & would normally go for core i5 or core i7)

Windows 7 Hdmi Output Is Only Available When It Is Off

May 25, 2012

i have a dell core 2 duo with 3gb of ram, and an ati hd4650, when i boot up, both outputs get the boot up screens, when it gets into windows, the hdmi output appears to be unplugged(not available for selection, just not there) it is worth noting that it worked fine under vista, anyways, when i switch the source on my receiver, or turn it off, as long as it is plugged in, it then gets detected, and i can modify resolution, and apparently it is outputting sound as well, i cannot verify this because the receiver is OFF, tried various versions of the catalyst drivers, and one of them worked, until i went into the catalyst center to change something and it went back to what it was doing i feel it is something wrong with the windows side or the driver, ive tried upgrading to the x64 version, ive tried different cables, different ports/plugs, it just wont work, i have no idea where to look in the registry to change when it is detected, but when i turn off the receiver or switch off of that source, the monitor flickers and the output is detected, this is frustrating because i wanted all of my home machines to be on 7, and i really dont want to go back to vista.

Can't Have Monitor And HDMI Plugged In At The Same Time?

Nov 27, 2011

I have a Lenovo H405-7223-1GU that I bought in June 2011. Yesterday I bought a Philips 32" HDTV 720p 60Hz. My PC won't recognize my TV at a monitor via HDMI cable. The ports on the TV and the cable is fine because I can connect my DVD player with no issues. Most help is saying to right click desktop, click "screen resolution"and then just tell the PC it's ok to send info over HDMI. That would be fine but I can't have my monitor and HDMI plugged in at the same time. As soon as the HDMI is plugged in my monitor (VGA) goes blank then comes back on with only the background image showing. No start button, no icons, no toolbar

Disable Sound Through HDMI Output?

Oct 24, 2011

When I connect my laptop to TV through HDMI cable, I get both video and audio from it to play on TV. And if I connect speakers to the headphones output I can't hear sound in speakers, the HDMI audio is still playing on TV. Is it possible somehow to disable the audio on HDMI so only the video will pass? Or maybe to make the sound from headphones output to play audio as well?

Can't Get Stereo Mix To Work - TV Plugged Into HDMI Port On PC

Aug 9, 2012

Currently having a lot of trouble to even get any sound out of stereo mix. I'm wanting to record sound from my PC but I'm not too sure if I can with the current set up I have. I'm using my Samsung TV which is plugged into the HDMI port on my PC and using the speakers already in/on the TV. I've went to the properties of stereo mix changed the "playback through this device" to my TV and I don't get any sound coming from Stereo mix on any program and the green bars aren't going up and down either.

Realtek Mute Rear Output When Front Input Is Plugged In?

Mar 9, 2010

This doesn't work. Very irritating.(I don't know if this RealTek sticky at the top of this forum is a solve for this, I'm not hot on registry changes and I'm not sure if this is a fix for this issue.)Firstly I have to turn off the front-panel detection in order for the front panel to be detected..?Secondly, I can't get the speakers to mute when the front phones are plugged in. I can do a manual switch from one to the other, but the front panel won't detect when things are plugged in.

May 29, 2012

I have an Asus K61-IC dual booting Windows 7 Professional x64 (default) & Fedora 16 x64.

I cannot figure this out for s#%t.

Can't Get 5ch Audio Via HDMI Out Of ASUS Motherboard On-board Audio

Feb 12, 2012

I have a HTPC setup. PC includes an ASUS MB with on-board video and audio, including options for either separated analog 7.1 audio out or HDMI out (among other output options). Current setup routes Audio and Video via HDMI to Pioneer VSX-1020 A/V receiver, and routes video from there to HDTV via another HDMI cable. OS is Win7 Ultimate x64, w/SP1.

Exact model for mb is here: ASUS M4A88TD-V EVO/USB3 AM3

When I play audio files, the receiver can fake the signal into all 5 channels (I don't have a sub, so the .1 is not relevant here), so there's no issue of the receiver not accessing the available speakers.

The main issue is this: When I look into the Sound Control Panel, under Playback Devices, the active/default device is ATI HDMI Output. Also listed are Speakers (not plugged in), Realtek Digital Output and Realtek Digitial Output (Optical). I do not have any analog cables plugged in, nor do I have an S/PDIF (optical/coax) connected. The HDMI works, but only gives me the option of Stereo (2ch). When I go to the Configure screen for the ATI HDMI Output, I see a list of Audio Channels, but that list ONLY contains Stereo.

No Audio Via HDMI To TV

Oct 27, 2009

I installed Windows 7 yesterday and at first I had no audio to my TV via the HDMI cable. I adjusted the settings via the sound icon on the taskbar, playback tab, changing whether the speakers or the Digital Output Device (HDMI), Sigmatel High Definition Audio Codec was the default. Eventually I got it to work.

Today, however it has stopped working again and no matter what changes I make, nothing works. When I right click on the playback device Digital Output Device (HDMI) and choose TEST, I get the message: Failed to play test tone. All sound comes through the laptop speakers.

I went to device manager and checked the driver for the codec and it was up to date.

When I was using Vista, to get the audio all I had to do was plug in the HDMI cable and the sound automatically went through the TV.

Does anyone have any ideas how to solve this?

BluRay Audio Via HDMI

May 18, 2009

I've been keeping an eye on these forums; I find that it provides the most succinct information regarding Windows 7.

I finally bit the bullet and made myself a HTPC running Win 7 RC 64-bit. The whole purpose was to play ripped DVDs (to VOBs) from my NAS, any downloaded shows (as AVI's) from my NAS, and hopefully BluRays via the BD-ROM (I have a PS3, so this was not the main reason).

It seems that I was able to get the first two objectives working without any work. All I had to do was install the latest Catalyst drivers.

However, I can't seem to get Cyberlink PowerDVD 9 Ultra (or Windows Media Center) to play BluRays with anything more than 'stereo.' I've tried to research the topic, but there's just too many acronyms flying around (PAP, AAC, AC3, etc) that reading forums is like greek!

From my understanding, I know I can't get the DD TrueHD (or DTS-MA) to work via HDMI. However, I THOUGHT I could at least have PowerDVD "convert" (is the proper word downsample?) the DD TrueHD to a 5.1 Multichannel audio.

Am I completely wrong? Is what I want even possible?

Get Automatic Audio From Pc To Tv Through Hdmi?

May 9, 2011

I have an Asus x83v laptop and recently upgraded from vista to 7. On vista when I plugged in the hdmi cable the audio and video would automatically go through the tv and back through the pc when unplugged (video would be displayed on both when plugged in). Now since I installed windows 7 only the video goes through automatically and the audio stays on the pc speakers unless i manually change the tv speakers to default in the control panel. How do I set it up to change automatically like it did in vista?

Can't Set HDMI Audio As Default

Dec 3, 2011

I recently connected my HDMI output from my LCD to my PC.I have Nvidia GTS 250. I looked around for some tutorials and solutions to my problem but non of them seem to work since they all say the same thing: set the HDMI as default in my audio settings. I tried but i couldn't do it because it wont let me. I open up Control Panel> Sound and I can't seem to find anything but my SPDIF. When I click on it, the "Set as default" button is not availble. I can't press it. when I right click on it.I had Nvidia Geforce 8400GS.Nothing. Then I updated to the latest drivers. NOTHING!So I installed my old GPU, Nvidia GTS 250 and also installed the latest drivers form their website and still nothing!I tried to remove and reinstall Realtek HD audio drivers and still nothing. When I right click my SPDIF option I see "test sound" and when I click it I can see the green audio thing goes up at the system tray.
