Ok, here's the solution. First I ran 'modinfo thinkpad_acpi' to see what options that module supports... I did that because I have run it before and remembered that what we are looking for is one of it's options... I found that "enable" is for enable or disable of the ALSA interface to the console volume control. Disabling it solves the problem and I have sound again.
Create /etc/modprobe.d/thinkpad-acpi.conf with at least: options thinkpad_acpi enable=0 ... and then reboot the computer. I'm not certain what package should contain that setting. I am sure that this is thinkpad specific, and not related to the problem mentioned above that was found on the other laptop model. I would begin debugging them in similar fashion, by stopping the pulseaudio daemon if it's even running, and then trying to run it from a terminal to see what it prints. -- No sound after Maverick Meerkat upgrade https://bugs.launchpad.net/bugs/647539 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
