I had always believed (I think based on what i had read on this list)
that software control of digital streams was a Bad Thing because it
involved resampling the nice digital data that some well meaning
studio had crafted for your maximum viewing/listening pleasure.

The perceived wisdom seemed to be to leave it untouched and pass it
through to your amp, and deal with the volume there.

Am I wrong? Was I right once but something has changed?

oh, and is the 'software' mixer a myth thing or an alsa thing?

Is there anything special I need to do to enable it?
