Yes, the bug also exists in upstream kernel - though I don't know if it's actually a kernel bug. (I just didn't know which package to pick.)
It looks like something caused the audio settings to change during the upgrade. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1244501 Title: Regression: audio stopped working after upgrade to 13.10 Status in “linux” package in Ubuntu: Confirmed Bug description: After the upgrade, sound stopped working for me. The volume would always be set to 100% after booting, though I couldn't hear anything. I went to the audio settings, and discovered that the hardware profile was set to "Digital Stereo (HDMI) Output". Changing it to "Analog Stereo Output" fixed the problem.
