I finally got everything to work. Here's the recipe. sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils alsa-source pulseaudio sudo apt-get install build-essential linux-headers-$(uname -r) module-assistant alsa-source sudo dpkg-reconfigure alsa-source sudo module-assistant a-i alsa-source reboot
Works. This leads me to suspect that there is some small inconsistency in code between the current rt kernel and alsa, or that the upgrade to the current rt kernel was not handled properly. If no one else says that this bug bothered them, or if some time elapses, this bug should be closed out. -- no sound ubuntu studio karmic https://bugs.launchpad.net/bugs/394282 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
