Same issue for me (with audacity) but only after upgrading yesterday for the first time after Christmas. After rmmoding snd_usb_audio and snd_usb_lib audacity worked fine again and it was possible to use the (video facilities of) webcam again.
I guess either the lock occurs in pulseaudio or in the kernel modules. -- no sound // 3:3:1: cannot set freq 16000 to ep 0x86 https://bugs.launchpad.net/bugs/459445 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
