In the last week or 2 I've noticed something odd with the audio - but as I don't use the it very much and also accept all the ongoing updates from Fedora I can't pin down when and what.
Anyway symptons are (using ALSA):
1. volume control button on the laptop - when decreasing to less than ~50% the sound goes to zero.
2. watching flash movies (in Firefox 3.5.1, Adobe 10 plug-in) (e.g. BBC, youtube): they play fine for a few seconds then go choppy (audio and video) then video recovers but sound is lost (and the laptop volume control does not work at all after that).
3. finding similar problems on replay of audio with kplayer and vlc on music files (ogg) that previously worked fine.
I've seen the pulseaudio and vlc fix thread but I don't use pulseaudio in kplayer, for example.
Just wondering if anyone has had similar problems...
