[Solved] Audio will only play in certain programs on new HTPC build
Update: Thanks to extensive googling and a 2010 thread at avsforum I was able to fix it. Turns out the speaker configuration has to be set to "Stereo" or you can't play audio properly. This is despite the fact that I have a 3.1 setup and 3.1 was an option, and all the tests worked. It's extremely counterintuitive, but everything is working now. This must be a bug in the Intel driver since my 5450 worked just fine set to 3.1.
My HTPC with G540 and Biostar H77MU3 will only play certain types of audio in certain programs, and I can't figure out why. It's connected via HDMI to my Pioneer receiver.
- Media Player Classic HC with Audio Renderer "System Default" using LAV Audio will bitstream DTS, Dolby, etc, from all my movies.
- Media Player Classic HC with Audio Renderer set to "VSX-821" (my receiver) will play MP3's.
- Windows Media Player will play my MP3's and other basic supported types.
- Youtube plays video and I hear sound in Internet Explorer
What does not work:
- Media Player Classic HC MP3's with Audio Renderer set to System Default
- Winamp will not play any audio files. It loads them but sits at 0:00 and won't start playing.
- Foobar 2000 won't play them either, "Unrecoverable playback error: Unspecified error (0x80004005)"
- Youtube plays video but there is no sound when played in Chrome
This all worked perfectly 2 weeks ago in my other computer with a Radeon 5450. Based on the symptoms I can deduce that the problem with all the non-working scenarios is related to them attempting to send the sound through the wrong or a non-existent audio device, but I don't know how to fix it. Winamp is my primary goal to get working, but I know if I fix the source problem everything else will be working too.

HDMI is directly out from the motherboard, no dedicated card.
Control panel playback device is Intel HD Audio, plus when I tap the slider I hear the expected system ding.
The deal with "audio renderer" in MPC-HC is for changing which audio device you want to route your audio stream. I always leave it system default so that way MPC-HC routes audio through what Windows is set to use as system default, which in this case is Intel HD Audio.
My problem is that half my audio programs won't send the audio stream through the system playback device. Windows default programs do (WMP, IE) but the rest won't.
