First off I have my PC connect to the receiver via HDMI. I have it set to PLII and whenever I play a movie or music the PLII icon disappears and it will only play in stereo or PCM. I have covered the whole manual a few times over experimenting trying to figure out what is wrong but cant find anything. Basically what I want is for the sound to come out of all 5 speakers not just the front L/R. whenever I play a game or anything 5.1 works great but soon as I change to music or a movie it goes to pcm and stereo options only.
Any help would be greatly appreciated.
You have the problem that I had for the last year since I bought the VSX-921 on Cyber Monday of 2011.
Once you have it setup correctly, as below, your receiver will dynamically change to Dolby, DTS, or stereo depending on your source.
The directions below are for Windows 7 and Vista, don't even bother with Windows XP.
1. Make sure you have set your speaker configuration to output as stereo on your PC (Dolby and DTS output as compressed 2-channel before being decoded and you want your receiver to get this stream untouched by your PC, stereo will just be stereo) via Playback Devices (google it).
2. Disable audio enhancements by choosing your playback device speaker properties on the "Enhancements" tab. Just check the "Disable all enhancements" box, then go to the Advanced tab and check the "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority".
Also, if you are using Windows Media Center, make sure "Audio Normalization" is disabled (google it) as this is considered an enhancement and will intercept the audio stream and decode it before it gets to the receiver.
The general idea here is that you want to "bitstream" the audio from your PC to your receiver so that the VSX-921 is doing all of the decoding. You can't decode the audio on your PC to multi-channel audio (thus why we disable enhancements and set the audio as stereo out) and then re-encode it to the receiver.
