yes.

actually it is -a `/usr/local/bin/a52dec -o oss6` ;-).
be carefull with the quotes to get the "-o oss6" through to a52dec.

i gave 6 as number of speakers. no options for line-in as rear/bass ...
the 8738 on my card has 6 separate outputs. there seem to be multiple
chip
versions with diffenrent output configurations.

no, not right now. i have the dvd-nav10 + lcdproc patches.

not quite. if you have additional dd-sound, you need to mute lpcm sound 
(press mute), as i have connected dvb-out to line-in. if you don't you
hear more or less echo.
no chance right now to set the volume for dd-sound (as this needs to be
done
via the soundcard mixer, which is not supported right now).
i would like to be able to select between all audio sources: 
languages and dd tracks.
maybe i will change vdr to use the soundcard mixer at least.
