Issue with Intel soundcard and jack detection
Hi,
I own an Asus P8P67
(https://www.asus.com/Motherboards/P8P67/specifications/), coming with
an integrated Intel soundcard. The specs identifies the chipset as
"Realtek® ALC 892". OS is Debian 8.1 x64, up to date running Cinamon,
but issue exists also with Gnome 3.
With the speakers connected to the front panel jack, I had random
volumes jumps, cracklings...
After investigating with "pulseaudio -vvv", I discovered that the jack
was detected/undetected. Logs looked like:
[pulseaudio] module-alsa-card.c: Jack 'Front Mic Jack' is now plugged in
2 similar bugs are here:
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1002480
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1004607
Please note that this is NOT an issue with my hardware/cables, since
under Windows I have no issue at all (with Linux, sound is not stable
more that 10 min).
I was not able to solve the issue, but I found a workaround: I changed
the jack detection delay like so:
# cat /etc/modprobe.d/alsa-base.conf
options snd-hda-intel jackpoll_ms=250
I'm fairly new to Debian, so I don't know how this could help others,
or maybe be included in mainstream Debian?
Thanks for your suggestions!
Regards.
