'Twas brillig, and Raymond Yau at 10/06/10 04:16 did gyre and gimble:
Can you explain how PA handle the volume controls of ac97 codec ?
PCM -34.5dB to +*12* dB Master -46.5dB to 0dB
The total dB range (PCM + MASTER) is -81dB to +*12*dB
Most user concern about recording without distrotion. (i.e. best result when Capture Volume at 0dB , PCM and Master Volume at 0dB ) and they need where are 0dB points
I'm not 100% sure how this is handled, but I know it's not ignored. You'll have to ask Lennart directly or dig in the code to see for sure.
