Package: alsa-utils Version: 1.0.25-1 Severity: important
db is not linear, but amixer believe it is.
"amixer get Master" says "Limits: Playback 0 - 74", then everytime I run "amixer -q sset Master 10%-", there is 8db dec.
For example, at first Master is 100% and 0db, both alsamixer and amixer think it is, and after I run "amixer -q sset Master 10%-", both alsamixer and amixer says Master is -8.00db, but alsamixer says it is 72%, amixer says it is 89%.
alsamixer is right, amixer calc and set wrongly.
Several months ago, they both right, and I upgraded, and amixer messed up. Please fix it. Thank you.
