Thank you for your bug report. Did you install any updates on that day? Could you try if booting a previous kernel would resolve the issue?

Thus the only sound that remains working is Built-In Audio Analog Stereo > Speakers (cheesy built-in speakers). This is what worked all the time during the ubuntu-bug test. Please rollback!
