Public bug reported: 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. ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1008177 Title: glitchy (pulsing) sound on Alienware box, 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1008177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
