I can approve that yes, it is on 13.2-RELEASE. How to reproduce: (Initially mixer vol =3D 100; hw.snd.vpc_0db=3D45) 1) Run as user: mplayer sometrack.mp3 (hearing clean sound) 2) Run as root: sysctl hw.snd.vpc_0db=3D4; mixer 70 (hearing distorted soun= d with roughly the same sound level) 3) Run as root: sysctl hw.snd.vpc_0db=3D45; mixer 100 (hearing again clean = sound) The sort of distortion is as of some poor sound and seems this is due to po= or algorithm calculating sound level amplification according to hw.snd.vpc_0db value. BTW, when rising/lowing sound level only by mixer or by mplayer interactive knobs, the sound remains clean. --=20 You are receiving this mail because: You are the assignee for the bug.=
