just want to confirm this is the correct behavior for the 2 relevant pcm drivers -- all default values -- both are outputting sound -- flac file from 16bit cd

squeeze is that no tweaking with the various default paramerters used above will produce a more accurate sound ? and in fact the Rpi 24bit output listed above should also sound identical to the Rpi 16bit out listed above ? ------------------------------------------------------------------------ oshcar's Profile: http://forums.slimdevices.com/member.php?userid=71999 View this thread:
