Comment(by paul at paulcatchpole.co.uk):
In the mean time I've tried setting the database field to the
"ALSA:softvol|surround51m" value and although my upmixed audio works as
usual, trying a DVD with the internal player appears to use 'softvol'
rather than the 5.1 PCM...
That's what it 'sounds' like in any case, and I'm guessing that the
'channels=2' in the setparameters line at the bottom of the following log
confirms that?
Interesting it doesn't report the audio device it's trying to open - that
would be useful - is that debug line enabled by a different -v flag?
