Audio :: LG TV Not Playing Sound When Connected Via HDMI Cable
Mar 8, 2014
As the title says, I've tried connecting my TV to my computer with an HDMI cable, and the video part works, but no sound plays. When I checked the list of playback devices, the TV appeared (as shown below), but it apparently cannot play sound.
I don't think I know anything beyond what I've posted,
Also, as a side note - I am completely unable to interact with any of these objects - I cannot set something as a default device; there is no response when I do it, and disabling the audio device only works until current sources of sound (like videos) are restarted.

I've bought an HDMI cable to connect my laptop to TV, i've gone into the control panel and checked that "show disabled devices" and "show disconnected devices" are both allowed and still i dont seem to get an option for HDMI for audio. The picture has come through fine, but nothing I do with the audio seems to work.

I sometimes plug in my LCD TV via HDMI cable to my laptop. I use it as a second monitor. The sound used to go to the TV as well. However, I inadvertently deleted the sound "profile" for the external monitor and I can't get it back. (I've attached a screen shot showing where the other profiles are, but missing the external monitor one).
How do I restore it so that when I plug in the HDMI cable the sound will go to the external monitor?

I have Windows 8.1 x64 and the following:
Radeon HD5450
Samsung TV connected via HDMI to graphics card
AMD HDMI High Definition Audio Device
Realtek HD audio
I have a strange problem that has not always been there but just recently if I don't have any sounds for about 5 minutes the HDMI audio seems to go into some sort of suspended mode and when I click on (generate) a sound (either system or music etc) it takes about 30 seconds for the sound to actually appear (manifest itself) through the Samsung TV speakers.
At first I thought it might be some conflict with the Realtek HD audio so I have disabled this (mobo built-in sound) in the BIOS and uninstalled the realtek drivers. This did not work.
I then thought it was probably an update to the Sound drivers or the graphics drivers for the ATI / AMD Sound card. I have installed the latest catalyst drivers and this did not work. I then fully uninstalled the catalyst drivers including the HDMI Audio and installed an earlier version 9.2.00 from 2012. This did not work either.
The only Playback Audio Device I have in the Sound settings is Digital Audio (HDMI) and I have tried disbling all audio enhancements. This did not work.
Please note that this happens even if I am using the computer (i.e. the screen can be on all of the time and it still happens after a few minutes).
Other things I have tried:
Power Config - disabled Link State Power Management for the PCIe card
One think I have observed (and I am not sure if this is a symptom or a cause) - The "Windows Audio Device Graph Isolation" process uses about 3-4% CPU while the 30 seconds or so elapses between the sound being invoked and it playing through the speakers. the rest of the sstem is relatively in idle. I can reproduce this by clicking on the sound and adjusting the volume a tad. It is meant to make an immediate "bing" sound to show the sound level is clicked or changed.
If I wait the 30 seconds then the sound eventually comes and then if I click on it again (or do other sound related things) then the sounds are instantaneous. Its only of I leave it 5 minutes or so with no sound activity. If I wait, say, 2 minutes the sound is instant too so long as their has been a sound event in the prior 5 minutes or so.

I successfully got bootcamp to work on my iMac, and the only issue that I have run across is that I do not have any sound whatsoever coming out of my speakers.
The sound icon just remains at the speaker with a red cross, and no matter what I do, I just can't get it to work.
In Device Manager, the sound device that is being used is 'AMD High Definition Audio Device', and I can't seem to find an update for it anywhere. Under the sound area of control panel, if I go to the playback tab it says that the only available playback device is 'AMD HDMI Output', and it says that is "not plugged in".

I have been struggling with this for weeks - whenever I plug my computer into a TV through an HDMI cable, the screen visual transfers perfectly but no sound comes through the TV.
note that I have scoured the forums and have tried all of the basic suggestions that people have given:
-HDMI or similar does not show up in 'Playback Devices'
-All of my drivers are up to date
I am running Windows 8.1. I have an ASUS Q550L notebook (can see all the specs here: Asus 15.6" TouchScreen Laptop Intel Core i7 8GB Memory 1TB Hard Drive Q550LF-BSI7T21 - Best Buy)

I just bought a new laptop and tried the HDMI, but there is no audio and the image is poor.
It's an Asus X501A with Pentium 2020M Ivy Bridge and Intel HD Graphics.
I tried changing the output resolution, to tweak the audio properties, etc.
No success.

I bought the plantronics .Audio 335 studio headphones, but when I plugged them in, it screwed up my sound. My compute'rs sound is now playing through both the headphones AND the laptop speakers. After unplugging it and trying again a couple times, I gave up and decided to just use my old headphones.
Except for the sound still played through both the headphones and laptop speakers.
Distraught, I restarted my computer. When that didn't work, I restored my system to a point I made yesterday. Still no luck. I've been scrounging google for a few hours now, and nothing is working. I REFUSE to refresh my system and reinstall all of my programs again.

I had my laptop for about a year now. The problem is after watching 3-4 videos, the sound will not work on the next file. I tried restarting and it worked! But after another 3-4 videos, there was no sound again. Another thing is when I open a music file, it works again. But the cycle just goes on.

the laptop is a ASUS K55A and originally came with windows 8. I've tried updating the drivers once the 8.1 version came out but the problem keeps recurring.
See what'll happen is, I can be watching a tv show or movie and once it's over or even if I pause it for say 10 minutes, the sound will completely cut out. I won't know this until I resume or play another video. It happens every single time, I don't get it. My only remedy right now is to open the task manager and restart the audiosrv service for the sound to work again. The funny thing is, the video will play to the end and when it stops, then the sound dies so it's not every x minutes.
On top of this, the video can be playing just fine but if I want to play a random flash video and pause my show for a bit, the flash video will play for 2 seconds then stop.

When the audio is on, for videos, games, music, etc. it sometimes "skips" like an old cd player. Its pretty obnoxious, and I'm wondering why exactly this is so. I'm assuming I have an old driver or something, because I upgraded my pc from win 7 to win 8 pro.

I have been having an issue recently with my Windows 8 HP laptop where it'll just stop playing videos (whether if streamed through the internet such as you tube or if played on the actual computer as a downloaded video) or the sound for said videos just won't play. The problem can usually be temporarily fixed by restarting my computer but it gets annoying to restart my computer constantly because a video is not playing or the sound is not working so I am trying to see if there is a permanent solution. Adobe flash player is up to date and the problem has been occurring before and after I updated flash player.

While playing a video or games or any app that has sound... the sound suddenly disappears if it is too loud. At first I thought it might be the driver... so i replaced HD Audio with Conexant... but the problem still persists, which lead me to believe that it could be probably the speaker's problem.
But while tweaking around I found that if i quit the video or the game, the sound came back to normal. And also when the sound goes off,the green bar on the volume tray icon still keeps jumping up and down indicating sound output. Hence audio troubleshooter was of no use.
When i opened volume properties,playback devices (a video playing in the background where the sound had gone off),as i switched between the tabs in the dialog box (playbackrecording,sounds,communincation) the sound came back! This cannot be due to the speaker.
I have reinstalled windows8, updated drivers and everything but no effect. What to do, as i cannot see movies or play games with speaker. Also headphones and external speakers have no problem whatsoever.

I have a AMD 5650 that shows a black bar that is 1 inch on the left and right and about .5 inches on the bottom on HDMI. I've used the drivers that Microsoft provided and also beta drivers from AMD from Febuary 2014, nothing seems to work. I've taken a picture, I've underlined where the back bars are in red.

Recently upgraded my Dell Latitude E6420 to Windows 8.
When I attempt to use my Sony TV as a second monitor via HDMI cable, I no longer get audio. Cable is fine and worked previous to upgrade.
Video comes up fine. In "Playback Devices" (with both "Show Disabled" and "Show Disconnected" devices checked), Digital Audio is greyed out and unable to be selected as a default device - simply says "Not plugged in".
I've tried updating various drivers, but to no avail.
Display adapters:

My friend connected an external monitor to his Sony laptop using an HDMI cable. The problem is that there is no audio from the external monitor speakers. The sound still comes out of the laptop speakers. When I look in Playback Devices, I see what appears to be the speakers as a device (can't remember exactly what is was called, but it was a somewhat vague name like "audio device"), and I've tried various settings, yet I can't get sound from the speakers.
So my question is, does an HDMI connection on a monitor support audio, or does he need to get a audio cable and use the green audio jack that is on the monitor, which I thought was just needed with the VGA connector.

I recently upgraded from W7 to Windows 8, and now my HDMI audio is acting up.
I have only ever used my Samsung TV as a monitor. When switching from headset to tv audio I used to click the sound icon and select "set as default"
Now I CANNOT select "digital audio (HDMI)" from playback devices, as it is grayed out, and says "not plugged in"
Strangest part is that if I restart my computer, it works just fine, and then somewhere from 30 minutes to 2h it suddenly stops working. It doesn't seem to matter what I am doing, watching a movie on VLC, netflix, or even just working on a speadsheet.
Also noteworthy: girlfriend has exactly the same computer, same problem!
I've tried updating/(un)installing the latest drivers from AMD, and Realtek, as well as re-installing windows.
Windows 7 64 (upgraded to Windows 8 64)
AMD FX 8120 8 core processor
AMD Radeon HD 7670 2 GB
Aspire M3450
Samsung 46" LCD TV

I just want to clarify that this didn't occur before updating to windows 8.1. Before the update my sound would switch between the tv and the laptop speakers automatically when as I unplug and plug in my hdmi cable. Now, I put my laptop to sleep when not in use or when transporting for obvious reasons and I really don't want to have to reboot every time I connect my tv.
Now my problem is, every time I plug in my tv, I get the usual switch over but the audio never gets to the tv. It shows up as usual in the playback devices and is the default. I'm not sure if it's drivers and ASUS doesn't have any audio drivers up for windows 8.1. I have read that this is a common problem with everyone. I'm not sure what else to do other than go through a lengthy process to backup and factory install my laptop back to 8 or wait for updated drivers.
The laptop: ASUS K55A w/ 8gb ram and upgraded wireless card.

I have the laptop as stated above, i have had it a week and the user before me had decided to put on 7 instead of 8. i completely wiped and restored to windows 8.1, installed all sammy drivers and ensured it is all up to date.
the laptop had huge instability issues, the hdd was on its way out as mbr was damaged and the heads were ticking badly. then i found the ram was not secured in the sockets properly too. so i fixed it all!
Anyways back to the problem. i have the realtek hd audio drivers installed from sammy, reinstalled the ones from realtek themselves and still nothing.
Main issue, mic and speakers built in work and are fully detected. but the microphone port and headphone port are not detected, no matter what i plug into them.

I have two displays, an HDTV connected through HDMI and an older LCD connected via DVI. All my audio comes through the TV. In fact, I've disabled the on board audio device on the motherboard. I noticed that the Audio tab in the Catalyst Control Center says "Your displays do not support audio.", but it shows my Panasonic TV in the Playback devices. The playback does work, but I get weird mutes.If I go full screen in Youtube or Netflix the sound mutes for like 30 seconds. When i anything (change tabs in Chrome, click a link, move windows around in a VM) on the other display, the sound mutes for 30 seconds. I basically am unable to do anything on my other display while something is streaming.

When my Turtlebeach x12 is plugged into my computer (runs Windows 8) and I try to launch some steam games the audio plays through the built-in speakers rather than my headset. I've played around with default devices and disabling/enabling different devices, but nothing has worked. In some games like Planetside 2, the in-game option to set the output device to the headphones works perfectly, but in most other games (e.g. Left for Dead), audio still plays out of my speakers. When I disable the speakers there is no game sound at all. This also wasn't an issue on my old laptop that runs Windows 7. Is there any way to here the game audio from my headset?

I have a windows 8 laptop and today the sound just stopped working. The windows audio service will not enable and everytime i try to enable it fails due to a duplicate in Windows Audio Endpoint Builder.
Now tricky part is i cant open control panel as it doesn't load, i tried reinstalling windows 8 but it also not load. This all was working perfectly just earlier today. I have no sound, just an x by the sound.

When I watch YouTube videos I get random stutters where the sound skips. The image doesn't seem to freeze though, just the sound
I also get issues with the sound streaming music online, where it pauses for a second and stutters even though it's not buffering.
When this happens, NT Kernel & System shoots up in task manager and uses more CPU than the browser. This by the way happens in every browser, IE, Chrome or Firefox.
It doesn't happen when playing music in iTunes or watching videos from my hard drive.
That being said I'm not posting about a buffering type stutter, I am aware of that and this is not it. This is like basically suddenly the computer has a big spike in memory or cpu usage and the video/sound clip stutters for a sec. But it happens often enough to be very annoying. In a 15 min YouTube clip it happened 10 times.
I have reinstalled my IDT High Definition Codec and my Intel HD Graphics 4000 driver, but still the problem persists.
