Bug ID: 194651
Summary: FreeBSD 10.1-RC3 audio hiss with powerd options on
Elitebook 2530p
Product: Base System
Version: 10.1-RC2
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: moert...@hotmail.com
I found one of the weirdest bugs in my life. It seems that powerd's options
cause hiss in the audio on my laptop. Here are the options from rc.conf:
powerd_flags="-n min -b min -a adp -r 90 -m 800 -M 2100"
and device.hints:
#turn off connections that don't seem to exist
hint.hdaa.0.nid18.config="conn=None"
hint.hdaa.0.nid26.config="conn=None"
hint.hdaa.0.nid28.config="conn=None"
#speakers
hint.hdaa.0.nid22.config="as=1 seq=0"
#headphones with auto switching
hint.hdaa.0.nid17.config="as=1 seq=15"
#build in microphone
hint.hdaa.0.nid21.config="as=2 seq=0"
#microphone jack with auto switching
hint.hdaa.0.nid20.config="as=2 seq=14"
