I can confirm that this is a bug with that particular card/module. I removed the card and switched to integrated audio (VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller) and problems have disappeared.
A possible workaround for the EMU10k1X was reported in the forums as working: System>Preferences>Sound. Click the Hardware tab. Under "Settings for the selected device:" choose the profile "Analog Surround 4.0 Output + Analog Stereo Input". Click the Close button. -- [Maverick] Audio playing too fast, using too much CPU https://bugs.launchpad.net/bugs/663876 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
