Hi all,
after a fresh install of Manjaro and initial problems to get my sound card
(Xonar DG, Chip CMI8786) properly recognized (adjusted alsamixer, followed by sudo alsactl store),
I still face a persistent problem with the sensitivity of my volume control:
If I adjust the volume via the command line with percent values (‘amixer sset Master x’),
I am muted for x = 0% and obtain the max. volume for any 1% <= x <= 100%.
Calling ‘amixer’ without any arguments, I can see that my Playback limits are in the range 0 - 65536, such that 1% corresponds to 655.
If I now set the volume to an even smaller value with, say, ‘amixer sset Master 300’ (no percent this time!), I obtain a reduced volume. Indeed, the command ‘amixer sset Master x’ is effective (roughly) in the range
0 <= x <= 480.
The manual volume control shows the same effect: Muted, if the ruler is shifted to the very left, and max. volume for any setting >= 1%. The only difference to amixer is, that once the ruler is shifted beyond 100% the volume starts to increase further… (but this is only a strange side effect and not my main issue)
To summarize, my problem seems to be related to the upper Playback limit (65536), which is way too
large in my case. Can I somehow set it (persistently) to a smaller value? (and if yes, where?)
If this is not possible, can I somehow modify the sensitivity of my sound card?
Many thanks in advance.
