Randomly no sound

[JG271]

This morning I was watching youtube at work. The sound was working just fine. Paused my video and stepped away for a few minutes. Came back and I now have no sound. Works just fine with headphones or plugged into some speakers. I have uninstalled the audio drivers and reinstalled them from the HP website. I used the HP Assistant to test them and I get no sounds whatsoever. I updated the BIOS and updated the software. I have also unplugged the battery and reconnected (i work for an electronic repair company, so this wasn't hard). Nothing is working. I can't imagine my speakers randomly went bad. There was no distortion to sound or any prior issues. When I go to Sound Setting > Manage Sound Devices... It shows "Disabled" underneath the speaker options. When I select Disable and then select Enable, it makes no change.

I now ran a hardware test and received the failure ID of 64P71A-9089LF-MFPUQK-21QE13

This morning the speakers worked again just fine. So I thought maybe it was just a random coincidence. After using them for about 5 minutes, they stopped again. The speakers didn't sound like they themselves were going bad, so do you think this is a motherboard issue?
