Hi y'all.
My media box has 6 channel output LF,RF,LR,RR,C,SW which I'm using with ALSA. Mplayer plays through all channels fine (settings in ~/.mplayer/config), but VDR sourced audio only plays in stereo from the LR,RF output.
Given that there is no way to play 'real' surround sound from pvrinput sourced audio, what is the easiest way to 'copy' the audio to the other channels, so I at least get sound out all the speakers?
Hmm, perhaps this is a setting in xine...?
The easiest way is to set a mixer option, provided that your card has one. Check with alsamixer for a mixer switch named "Duplicate Front", "Surround", or similar.
If there is no such option, I believe this can somehow be achieved with alsa config files as well.
