If we add in ISA cards, it's not a very generic assumption at least. For example on my cs4236, "master" is -94,5 to +12 dB with 0dB at "87" in the integer scale.
It's a "Master Digital Gain" -- not sure what that "digital" implies as it very much seems to be positioend in the post output mixer analog path...
Maybe the driver should add an internal offset to the dB scale, to guarantee that 0dB is max, instead of just copying the hw specs?
No, really quite definitely not. 0 dB means no attenuation of amplification. How loud that actually ends up is very much dependent on what's _behind_ your line-out.
Yes, but what I am asking for is to define the dB values of the master control relative to the some ref level on this line-out. What happens after the line-out doesn't matter at all.
