Hello: I think that I'm suffering from the same problem on Natty, because I'm also using a SPDIF output and sound stops working suddenly, after awhile, without a clear origin.
In my case, restarting PulseAudio is not enough. I even logout and login again on Ubuntu, using the same account or another, but there's no sound back. However, if I put the system in hibernation and then wake it up, sound starts working again (thanks to a tip from another user on the Ubuntu Forums). These symptoms make me think that it has nothing to do with PulseAudio. Am I right? Some people have reported similar problems here: http://ubuntuforums.org/showthread.php?t=1760669 . I'm not sure if all them are related or have a common origin. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/783682 Title: sound stops after a random interval To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/783682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
