yes. you'll need to raise the DAC volumes.

what program did you use?
if you want to duplicate signals to surround ,etc., you can configure
it in your ~/.asoundrc file. (only for ALSA apps, though.)
we don't do signal duplication in kernel.

yes. it's not a typical consumer card.
if you have 6 or 8 channels, which should be called "Master"? :)
> C) mplayer (http://www.mplayerhq.hu) compiled with alsa support will detect the card but fails a snd_pcm_hw_params_set_format call. It will work fine via OSS emulation however. The same build of mplayer works fine via alsa with other cards, tho. Is this a driver problem, a hardware limitation, or a problem in mplayer?
the problem of application. the application should use plug (or
other) plugin to convert the sample format on user-space.
