Title:
connecting headphones mutes sound after latest updates on Pavilion dv6
laptop
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
07 Dec 2012 I installed the latest ubuntu 12.04 updates on my Pavilion
dv6 laptop. This came with a kernel update 3.2.0-35
I always leave my headphones connected to the jacks (left side,
mic=red, ears=black). I don't use the built-in speakers very often
and don't unplug my headphones.
I noticed something strange after latest package updates and
restarting because there is now a light on the keyboard f11 / mute key
showing the sounds is muted. This didn't happen before.
If I unplug the headphones then the light goes out and it unmutes. I
can hear sound through the laptop speakers. Both +/- volume buttons
work and mute key work and the OSD displays correctly.
When I reconnect the headphones the light comes on f11 mute key and
the sound disappears. The OSD still shows the master volume as 100%
I went into system setttings.... sound... changed the connector from
Headphones to Speakers and it seems to fix the problem but this is not
permanent, as I now have to do this after every reboot.
It used to work perfectly well before Yesterday so is there a way I
can get it back the way it was? Thanks for any help.
