Hello everyone, first I confirm that this problem is still present in precise.
Second: I frequently have multiple users (at least two) graphically logged into Ubuntu when I suspend the machine. There is a bug that is about how default sinks get muted after suspend, when more than one process of pulseaudio are running: Bug #569526. I suspect that it's related to our problem. Can someone with a little more knowledge than me (I'm sorry I don't understand enough of the internals) have a look at Bug #569526 and confirm that it's related? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/665314 Title: USB audio device is always muted after resume from suspend to ram To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/665314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
