I'm inclined to try on the ALSA bugtracker -- bug #3008 <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3008> is the same problem/hardware.
I may be naïve, but looking through other bugs with similar symptoms, I think it's a problem with I/O configuration for the Realtek chip -- perhaps the acpi thing is a red herring. -- Low Audio Volume/other audio problems with Lenovo 3000 C200 https://bugs.launchpad.net/bugs/84616 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
