I am also getting this on Precise: audio looping and little black holes in responsiveness.
Like with ubuLinux above, I get UI lockups for a split second and my PC is an i7 3930K with 32G of RAM and the OS installed on SSD's so it is definitely _not_ a lack of available resources. I have also tried turning off the PulseAudio timer scheduling to no avail, although now the loops in audio are shorter and slightly less frequent - perhaps there are multiple bugs with similar symptoms in play. Perhaps this bug is related to bug #751298, bug #1045771 and/or bug #1019693. Let me know if I can give any hardware info or logs. ** Tags added: pulseaudio -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1008177 Title: glitchy (pulsing) sound on Alienware box, 11.10 Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: This bug has persisted and occasionally recurred from 10.04 on, and it's still there in 11.10. The problem is a periodic cut-out of the sound, so it sounds like it's pulsing with a beat between 1 and 2 per second. My ALSA information is at http://www.alsa- project.org/db/?f=63bdde325703c11f4858432f559ecd55d5d93e70 . On the "Sound Preferences" dialog, I have three hardware devices available, most of them don't work at all, but "Internal Audio"'s Surround 4.1 and Surround 5.1 give audio with the pulsing, which even affects its speaker test. Interestingly, the "System Test" program plays its annoying tone without the ululation. I tried installing the ALSA Developer's releases on 10.10, I'll try again here, but I was greeted after my upgrade by the cutout affecting the startup sound.
