[Alsa-user] No sound from headphones on hda-intel codec ALC3228

[Moshev <mo...@gm...>]

I'm having trouble with getting sound from the headphone audio jack of an
HP zBook 15 G2 laptop. Under windows (8.1), I also get no sound if I use
the generic intel hd audio driver - I have to get the specific one from
HP's site. Sound from speakers is heard regardless of whether I'm running
linux or windows with HP's or the generic driver and speakers are muted
when headphones are plugged in.

I have ran the alsa-info.sh script and information is available at
http://www.alsa-project.org/db/?f=4ee99413a52d530e081240b65d8500bba9a046b4
. The codec is reported as Realtek ALC3228, which I can't find much info
about online and Realtek's own site doesn't list it, though google does
show other HP products with the same audio device. I've checked that the
headphones aren't muted in alsamixer. Beyond that, I tried playing with the
model option by writing to /sys/class/sound/hwC0D0/modelname, then
triggering a reconfigure, but nothing worked.

Any help in resolving this would be greatly appreciated.
