I have exactly the same problem with a different sound card, which is listed in lspci as
Audio device: ATI Technologies Inc RS880 Audio Device [Radeon HD 4200] on an MSI 890GXM-G65 board. Booting 2.6.35-24 fixes the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/704401 Title: Optical sound output breaks on upgrade to linux- image-2.6.35-25-generic -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
