--- Comment #8 from mrj at advancedcontrols.com.au ---
Here's the same PA volume to ALSA volume mapping under 3.11.9. Line and mic are
identically monotonic.
LINE MIC
0, 0 0, 0
1000, 0 1000, 0

Note that the 3.12.5 mapping in Comment 6 is slightly wrong because I didn't
know PA commands were asynchronous, and that a delay was needed before the
hardware volume was read. (The hint was that the top volume of 54 wasn't used.)
The correct table is:
LINE MIC
0, 0 0, 0
1000, 1 1000, 1
2000,13 2000,13
3000,20 3000,20

8000,37 8000,37
