What happens to my sound?

post #1 of 8

Thread Starter 
I have an issue I have Google'd about, and have founds others with the same problem, but no solution.

HTPC stays on 24/7, and right now I *think* I have all power management turned off (ie, my HDDs don't go to sleep, etc)

TV, however, gets turned off, or switched to another input (say DVD player, or Roku, or cable)

When the TV is turned off or switched to another input, the HTPC loses sound. So, if I switch to the Roku for a while, when I switch back to the HTPC, I have a red X on my speaker in the system tray. Right now, our solution is to unplug the HDMI cable from the back of the PC and then plug it back in.

Is there another solution for this???

TV is Samsung PN42B450 http://reviews.us.samsung.com/7463/PN42B450B1DXZA/samsung-pn42b450-42-720p-plasma-hdtv-2009-model-reviews/reviews.htm

You need to list all your hardware.

well anyway sounds like you might have an ATI card, if so you need to change drivers.

First and importantly do you have the AMD HDMI Audio driver loaded and as your default audio device? What does your PC see when you switch the TV to another HDMI input? e.g. do you have a second monitor/speakers connected & configured? CLEARLY you're only using 2-ch stereo TV speaker audio as well... You need to set teh CCC to NOT auto-detect the EDID, thus it won't care what it's connected to. Also, which CCC are you running - 12.6 at least and there's a new driver set -- go looking in AMD for an APU driver suite for your Win 7 64-bit and see how that helps. I just loaded it on a small E-350 (HD 6310) nettop I have which improved my graphics WEI scores!

I installed the HD sound driver that came with my motherboard. My current HD audio driver is version 7.12.0.7706 dated 2/23/12, and it is set as default.

I do not have another monitor attached. All I have to connect monitors is HDMI cables, and if I unplug from the TV to plug into a monitor, it fixed the problem. (Sorry we are stationed here temporarily, so 75% of our stuff, including my extra monitors and different connector cables, are packed and in storage)

Hmmmm....CCC is Catalyst Control Center? If so, I don't have that on the HTPC, I have AMD Vision Engine Control Center, version 2012.0504.1554.26509. I don't find any options for EDID (I don't know what that is, but I couldn't find it anywhere in the Vision panel) Can I switch to CCC?

Thanks for your assistance!

I ran into a similar issue Catalytic. On my htpc the microsoft drivers kept being installed I had to go to device manager and manually uninstall the audio drivers and then re-install the amd driver package. The other issue is that microsoft seems to randomly set your desktop to 1024x768 when you put the computer in standby and when the monitor/hdtv is disconnected this *should* change back to your default resolution but doesn't always. The only fix I could find for this was a registry setting.I will edit my post when I find the registry entry again.

I had the same issue as well. Every time I turned my television back on, while the PC was on, the HDMI audio out option was nowhere to be found. I updated the bios and all drivers using MSI live update and AMD's Autodetect software from their website. Sound is now working when I turn my television back on.

Hope this helps.

I'm using an HD 6450 to supply video to the TV via HDMI, but am using SPDIF motherboard audio going to the AVR. The SPDIF audio got disabled almost every day when I turned on the system. IIRC I rolled back the mobo audio driver to the basic Microsoft version & this solved the problem. If updating your driver does not solve the problem maybe you might want to try an older version.
