Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I installed and booted `3.15.0-031500rc4-generic` and reinstalled alsa again but it didn't seem to fix anything.

Spencer Deinum, as per http://support.asus.com/download.aspx?SLanguage=en&p=1&s=39&m=P8H77-I&os=&hashedid=8rrhd5iJZMNojc2z an update to your BIOS is available (1101). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.

I actually came back to work today and went to boot up the machine and it looks like the motherboard is fried.

The sound was working fine up until a few days ago so I'm going to blame this on one hardware, sorry for the false alarm!
