How To Automatically Change Audio Device When Inserting HDMI Cable
May 4, 2012
My lapotop is HP Pavilion 9750 running Windows 7 Enterprise (with the latest updates). When I'm inserting the HDMI cable to view my screen on the TV it automatically shows the video, but I have to manually change the default playback from "Speakers" (Realtek High Definition Audio) to "Realtek Digital Output" (Realtek High Definition Audio) so I could hear the audio from my TV and not from the computer.
Is there a way to make that switch automatically when I connect/disconnect the HDMI cable?
i'm wondering if there is a way to automatically change the audio playback device depending what monitor the application making noise is on. for example when i watch a Internet video on either of my 19 inch desktop lcd monitors i want to sound to play through my pc speakers. if i play something on my lcd tv through hdmi i want the sound to play through the hdmi to the tv. ive done alot of searching and i cant find anything anyone have any suggestions?
I have happily been viewing movies etc from my laptop to my TV via an HDMI cable for the last 2 years. However, I installed Windows 7 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. I downloaded all available updates from Windows and my laptops software updates and just now re-installed my sound and video drivers but to no avail.
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.
I have connected my hdmi cable as usual but this time i had on tv display NO SIGNAL. When i connect another pc to check the cable it seems to work correctly.The problem is coming from my pc.
this is the msg appearing in a black surface of my pc. i have this gateway one zx6000 for about a year and a half.windows 7. i dont have my disc anymore. i have tried changing the bios to hard disk drive only and disabled the other devices but still not giving any changes. how will i reboot this pc without a disc?
In the Sound options window, you would see your several devices under Playback and Recording Devices. The thing is I have audio devices that have a number next to them, eg. "2- Creative Sound Blaster". Windows always does this, but I would like change these device names, and I don't know how.
there is a better way to change my audio playback device in Windows 7 (Ultimate, Service Pack 1, 64 bit). As background, I keep my headset plugged in at all times and swap to it when needed, but like to use my speakers most of the time.
The only way I've found to swap between headphones and speakers is to right click the volume button on my taskbar, open "Playback devices", select my headset (listed as "Speakers, Realtek High Definition Audio"), then click "Set Default".
Aside from feeling rather tedious, the swap is not recognized in nearly all programs if they're already active. In other words, if I boot up a program with my speakers set to default, swapping to headphones via the above process will not change the audio output device for that program until I quit it completely, set the new default, the restart the program.
I recently updated my NVIDIA card with audio drivers and now it can make the audio go through my television using HDMI (watching videos). The problem however, is that when I go into the Sound settings and change the default to the NVIDIA "device", I need to reboot windows to activate the change. I have tried going into the mixer and the sound setting and I can't figure out a way to change the active audio device without having to reboot (or even just log out and log back in).
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.
I have my computer hooked up to a home theater system. Most of the time, my computer audio output is set to my on-board motherboard audio connected to simple speakers, but I frequently switch the default device to digital output through my sound card (HTO Striker 7.1). My goal is to create a file that I can keep on the desktop that will switch the default audio device. In a perfect world, it would switch back and forth between the 2 settings that I use, but I understand that it might be too much to ask for. I have a bit of experience with batch files in XP, but that was essentially reverse-engineering things that I found online.
from the digital audio device? every time i plug in my $20 speakers i got from target, the audio device changes from my soundmax driver (which comes thru the lappy speakers) to a digital audio device in my little speaker icon thingy and i don't know how to manually change it back except thru reinstalling the drivers and rebooting a bunch of times,when i go to properties it only shows the enabled device and i can't find the other output option. if i reinstall the soundmax drivers it switches back to laptop speakers but this is obviously a hassle.
Just bought a new Nvidia GeForce 8400 GS graphics card to replace my dying onboard video.I have a Vizio HDMI TV however I am not getting sound through the HDMI cable. Was under the impression HDMI transmitted video as well as sound.Not sure if the problem is with the TV or with the Video Card?
I'd like to hook-up my computer to TV. I used an HDMI 30 foot cable from my computer to the TV and it didn't work. Cable is fine. How far can usually go? A$U$ CM#68-70-CA-3AA Desktop PC Intel Core i7 3770(3.40GHz) 16GB DDR3 2TB HDD, NVIDIA GeForce, GT630 2GB, Windows 7 Home Premium 64-Bit.I can only assume that there is not enough power in my GeForce630 to send data through to the TV at 30 feet.
So I bought this kind of HDMI cabel I have a HDMI port on the backside of my case and my motherboard should support it.So one end going into the HDMI port on the case and the other one goes into the TV, but my computer is not recognizing it.I'm trying to dual screen, I have a normal PC monitor which is working fine, however the HDMI for the monitor looks like this and works just fine, what could the error be?
I have a Windows 7 enterprise 64 bit pc and an Onkyo receiver. I used to have them linked with an aux cable for music. But since I had enough of the bad sound quality I bought an optical cable and connected it. Now I have the problem that my subwoofer gives a lot of less sound then with the aux cable with the exact same settings and music. Also my pc recognises the optical cable as an HDMI cable and I don't think this is right. I can't change any settings either in the sound.
Pc Wizard told me I have this onboard sound card: ASRock SB600 High Definition Audio Controller Pine Technology HD48x0 audio
I have aspire 7745 laptop running windows 7 premium 64bit. I had the video & sound working on the TV via the HDMI cable but it stoped working. Now the TV "sees" the HDMI signal (and receives a low tone) & the computer "sees" the TV as a secondary display in the device manager. but no signal or sound. i have tried many ideas found here and other places on line but no change.
I just reinstalled Windows7 from recovery discs on my Dell desktop. Sorry, I don't know much about what hardware I am running, but windows7 is a fresh install and everything else works OK. When I plug the HDMI cable from the pc to the tv all I can see is the desktop background with no icons or desktop folders. I can't see any programs either. I do have sound though.
What's been going on with my HDMI port. 2 nights ago I was watching a movie through my Dell Inspiron N5050 laptop through my Panasonic HDTV. Yesterday, I tried to connect my HDMI cable to my laptop and computer, but nothing happened...So frantically I've been searching everywhere and trying what I have so far with no progress...
1.System Restore to earlier date when my HDMI port was working. 2.Toggle Computer/Duplicate/Extended/Projector Only and nothing worked(Also made sure tv was on the right HDMI input) 3.Tried 3 different HDMI cables and HDMI inputs 4.Uninstalled all sound drivers and Display Adapter(Intel(R) HD Graphics Family 5.Contacted Dell and had them try to reinstall drivers 6. Checked BIOS but I couldn't find any enable/disable feature for video. 7. Took battery out of laptop waited for 30 seconds pressed power button to reset.
My Panasonic TV doesn't even show up under my playback devices and when I try and do a dual screen through screen resolution it says another display not connected. I've tried going Intel HD Graphics Control Panel as well...no such Luck! Beginning to think that my HDMI port on my laptop is broken.
So, these are giving the main performance to my machine. I have also a nice Samsung D5000 TV (32" ) FullHD. When I connect my Laptop with a TV, computer start lag. It even doesn't use all of CPU (20-25%, while playing 720p video in TV with 10 fps (Fraps)). I've all latest drivers and everything should work. Using Windows 7.
The problem I am having is I have connected my pc to my samsung tv The image and sound are showing up on the tv, however, I am getting an error message on the tv saying NO SIGNAL.

I have an HP Pavilion Elite HPE machine, Windows 7, Radeon HD 5700 Series graphics card, connected to an Acer monitor and HDTV. Here's details on my setup:
My Equipment | Building a Home Theater With Your Office PC
My problem is that even though my HDMI cable's plugged into my Radeon graphics card, sometimes the PC only recognizes the Acer monitor and not the receiver (that's connected to the HDMI cable and my HDTV). So I end up having to plug and unplug the HDMI cable several times (sometimes 10+) before it recognizes the HDTV/receiver connection. Is there any setting that would favor the card/PC recognizing the HDMI cable more frequently? I've heard it's a handshake issue, and that maybe using a different type of cable would work. But wondering if there's a setting I could use before switching out cables.
I have an Acer Aspire laptop running Windows 7 Home Premium x64.
I regularly connect it to my TV monitor via HDMI cable and fall asleep watching movies (played on VLC or Windows Media Player). I set the computer to go to sleep after 1 hour.
Multimedia Settings are set to "Allow computer to sleep" under "When Sharing Media" in the Power Management section.
Screensaver is disabled. I have overrided my audio driver, since powercfg command suggested it may be a conflict.
If I am playing a movie without the HDMI cable plugged in, the computer goes into sleep mode right on schedule. It is only when I have the HDMI cable plugged into my TV monitor, that it refuses to enter sleep mode.
