After fresh installing 13.04 at my HP ProBook I can have sound only in one application at a time. When I use Skype, there's no sound in Clementine, SMPlayer, etc.
I tried to reinstall ALSA and PulseAudio like this:
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload
But with no effect.
In Skype, I have only ALSA (hw:....), there's no 'PulseAudio' option.
hw:x
?PulseAudio
device - there's no such option.
