Hello,
My openSUSE 13.1 64 bit KDE Current laptop developed a weird habit a few months ago: Whenever I unplug it, I lose audio output from internal speakers and headphones (plugging the charger back in doesn't do anything). Clearly this must be some power saving feature gone wrong. The KMix meter goes away completely or its name changes to "Dummy output". Veromix gets all confused as well.
Restarting pulseaudio doesn't help. However, if I go to the Sound settings in Yast, there make some change to the driver settings, and then cancel the changes after Yast has restarted the sound system, this restores my sound most of the time. It is also notable that my bluetooth speakers usually keep working just fine if my audio output is directed to them via pulseaudio.
Some help fixing this would really be appreciated!
In the context of my statement that this may be a power saving "feature", let me mention that around the same time that this became a problem, I had to make a few changes to my system to prevent it from overheating. It has hybrid graphics (intel/radeon) and until I installed kernel 3.14, both would run at all times at full power. I also installed laptop-mode and maybe a few other programs. I checked the effect of changing laptop-mode's sound settings, which apparently aren't to blame.
/usr/sbin/alsa-info.sh
Thanks in advance for any help you can offer.
