Now, as to what the sound card actually supports and what the drivers support, I have no idea. Certainly not being able to control the volume from the digital jack is not a new thing. I suppose the mixer controls probably control analog mixers on a sound cards...? If that is the case, then it explains why control of the digital output level is generally not found. From a practical perspective, your better off to pass the unscaled numbers to your home theatre receiver. The reason for this is if say you cut the volume to 1/4 (1/(2^2)) of its maximum in amplitude and you are sticking with 16 bits of precision then you have lost 2 bits of precision. Of course even hearing the difference between 14 and 16 bits is not that easy, and hearing the difference once you move to 24bits may in fact be impossible. -Robert _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
