I'm having the same problem with Natty, and the issue happens randomly. However, it is possible that while the issue is happening (i.e. playing a video), other applications are able to output sound correctly while the distorted audio is being played back (discovered this today).
I'll update with more information as I find it. Also, feel free to request information of me and I'll try to help provide it as best I can. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778446 Title: [SB-XFi - Creative X-Fi, playback] Sound is distorted -- (Echo with garble) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
