Hi,

I have M-Audio 7.1 soundcard with profile "Analog surround 4.0 Output + Analog Stereo Input" in use from the sound preferences. (Using 2 speakers and headphones). Using newest Ubuntu and latest updates from repositories.

When I try to play a video the sound comes fine but after ~1min 27s (it's pretty much this every time) it stops. Debugger in console shows this:

I can disable the audio track and toggle it back and I can hear sound for another 1min 27s, but then it's this all over again.

I've tried using different output modules from VLC (default/PulseAudio/ALSA) and it does this with everything.

If I use default output module from VLC and "Analog Surround 7.1 Output"-profile from sound preferences the sound is continuous. However, there's a big flaw with this. VLC interprets my system as 7.1 architecture, which it is not since I would like to have identical sound outputs from headphones and regular speakers. My system handles my speakers as front speakers and headphones as rear ones. (Also in ALSAmixer)

So the sounds I hear from surround sound movies are only soundtrack and such which are usually played from front/rear speakers. Movie clips without surround sounds work fine.

How to correct this or to set it so that I can use 7.1, but with front/side/back left having the same output and vice versa for front/side/back right. I would be fine using the 4.0 system too, but it has the problem that the sound stops playing after a while.

I am having this same problem. The sound just cuts out after about a minute and a half. If I shut off the track and turn it back on it works for another minute and a half and then cuts out. Ditto for using different output modules. This seems to be a relatively new development. The video files I have noticed this on are all .avi's, if that helps. Thanks.

Cheers,

Update: same problem (though after a different time duration) when playing DVDs in VLC. I am using VLC 1.1.11.

Cheers,

No one is having/has had this problem? Nothing? Can I provide any more helpful information?

Reinstalling seems to have fixed the issue for now. Still not sure what was wrong, though...
