Good morning.

Today I was playing with sunvox and (probably after that) sound became quite or very distorted in many applications.

Thanks.

add:

If necessarily:

ben@pav:~$ sudo alsa reload
[sudo] password for ben: 
/sbin/alsa: Warning: Processes using sound devices: 2175(pulseaudio). 
Unloading ALSA sound driver modules: snd-hrtimer snd-hda-codec-conexant snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-page-alloc snd-seq-midi snd-rawmidi snd-seq-midi-event snd-seq snd-timer snd-seq-device (failed: modules still loaded: snd-hrtimer snd-hda-codec-conexant snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-page-alloc snd-seq snd-timer snd-seq-device).

Sound was moved to the medium level in alsamixer. After killing pulseaudio I got no sound at all.

Some additional info:

Doing

sudo apt-get purge pulseaudio gstreamer0.10-pulseaudio

sudo apt-get install alsa-utils gstreamer0.10-x

gave nothing.In gstreamer-properties I can see no output devices there and in sound menu element.

In that case, do you use VLC? VLC comes with its own codecs and might conflict with others. Try uninstalling VLC and retry.
