On that note, I just acquired an Audigy 2 (SB0240) that I'm testing with and now that I'm paying attention to it due to this thread -- its 0 dB setting is very significantly louder (with everything behind the line-out constant ofcourse) than the 0 dB setting on my TerraTec DMX.
James, I believe you are the emu10k1 person? Data:
TerraTec DMX = ESS Canyon3D (ES1970MS-3D) + Sigmatel STAC9704T
Creative Audigy 2 (SB0240) = Creative CA0102-ICT + Sigmatel STAC9721T (+ Crystal CS4382-KQ which seems to provide digital attenuation as well)
At 0 dB master the Audigy 2 is much louder than the DMX is and audibly distorts. Judging by hearing, keeping the master at -16 dB (60 in the integer scale) gets things about the same. Was that scale provided by datasheet or just guessed? Especially the distortion would seem to indicate that something is actually doing analogue amplification at the 0 dB ALSA setting...
Expanding, with the 'Line' control at 0 dB (74 integer) and 'Analog Mix' at 0 dB (100 integer) everything does sound right with both 'Master Capture' and 'Master' at full, and too faint with 'Master' at -16 dB. I guess this indicates that it's something at the DSP side only? (sort of loosing my way in this bewildering array of controls so if I need to be guided to possibly say sensible things -- please do)
When I do actually capture, -16 dB master is again the correct setting when playing back (with everything else still set to 0 dB as described above). It's then equally load as when directly monitored during recording. I expect then the Master dB scale needs to be adjusted down? If yes, I'll try to make very, very sure that -16 dB now is the correct new 0 dB.
