Hey! My sound went out. I did some updates that got my rear panel audio jacks working with a set of drivers that weren't from HP, and when I updated BIOS from the manufacturer. It changed the display of my sound properties, but my audio jack was working. I'm on a HP 500-314 with a six panel audio jack on the back and a headphone and microphone jack on the front panel. The sound left in three stages. First being a reinstall of the IDT Audo Codec from HP, then they went out after a Windows update and changed order during a BIOS update. When I reinstalled new drivers this time, the front panel stopped working completely, but audio was able to play through L R Lime green on back panel, only. Last night I downloaded AMD Overdrive and one of the settings bumped "L R" Lime green off and I couldn't get it back on.
In this photo, "Speakers" is the bottom half of the six panel on the back with left, right and subwoofer speakers. None of them work or are seen a plugged in. "L R" Lime green is next to the microphone jack on the back and is the jack that was working yesterday until it left the building. When it was working, it was picked up under "Digital Audio". Pretty odd.
"Digital Audio" used to change when you jacked in a set of speakers or a headset, and now it's a default setting with an audio jack that I don't have, but it was working.
I went ahead and changed the drivers through Device Settings to the default High Definition Audio driver instead of IDT Codec. Last night I used the UEFI to reinstall from factory settings and went from Windows 10 to 8.1. It didn't change any of the sound properties, and it changed the drivers back to IDT. I can't figure this one out...
