I have the same problem - specifically, the audio clicks and crackles. It started with a fresh install of Ubuntu Desktop x64 v10.04, on the latest patch of Parallels 5, with the most recent Parallels guest tools, running on Mac OS X Snow Leopard with latest updates.
I have 8gb installed RAM, and 4gb dedicated to Ubuntu. (I use x64 because: 1] so that I have access to all 4gb, and 2] because I run several copies of Desktop x64 natively on other machines, with 8 or 16gb RAM, so I want to be consistent with the distro, and solve common problems only once.) Has persisted across all updates of host OS, Parallels, Ubuntu guest (and app package installs), and Parallels guest tools. Recently, I've tried countless various fixes, with no effect. Problem is no better or no worse. -- [ICH - Intel 82801BA-ICH2] PA test tone failed (alsa tone succeeded) https://bugs.launchpad.net/bugs/629998 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
