I confirm this bug, its happens exactly as Cameron Harris wrote, in my case the sound card is HDA Intel ALC888. After the start-up the Sound Preferences applet doesn't show any output devices, restarting pulseaudio helps.
On a side note, my user name wasn't associated with any of the pulse audio groups, probably Cameron's user wasn't either, therefore he got choppy sound after restarting pulseaudio, since his user isn't associated with pulse-rt group. So Cameron, this should help you as it did for me, as a temporary workaround: First of all, in System -> Administration -> Users and Groups, click on unlock to get full access. Now click on Manage Groups button, in the groups': pulse, pulse-access and pulse-rt properties check your user name, this should help with choppy sound. You will have to log out and log in again for the effect to take place. Now, when you need to restart pulseaudio, you kill it as you wrote with: killall pulseaudio and then you can restart it with: pulseaudio -D the D switch is for daemonize, so pulseaudio will continue to run in background, and you can close the terminal now. -- Pulseaudio daemon needs manual kill/restart every boot on HDA Intel ICH7 https://bugs.launchpad.net/bugs/322760 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
