[SOLVED] Rear Audio Jacks Not Working After Power Surge/Outage

[acets114]

We had a very short power surge/outage -- maybe 1 second -- and now my motherboard's rear audio jacks (headphone line in and microphone) don't seem to work. I moved to the front audio jacks, and they do work... Any idea?

Are those "rear" audio jacks on the motherboard or on a audio card?

Power down, unplug, open the case.

Clean out dust and debris.

Use a bright flashlight to inspect the rear audio ports and any connecting cables for signs of damage: swollen components, melted insulation, blackened/browned areas, bare conductor showing.

Look in the sound settings and Sound Control Panel settings. Are the settings as expected?

Motherboard. I edited the original post to reflect that now. Thank you.

Sound settings were the same as before the power outage, from what I could tell.

I'll inspect the inside and let you know my findings.

Worst case you can get a usb sound card that should work.
