Sound went away

I don't have a sound card installed. I'm using the onboard sound on the mobo. I do have a SB card but I can't install it because I'm running my SLI setup and a video card is blocking the PCI slot that I could put it in. The mobo is an ASUS Sabretooth so it has a 5 year warranty. Maybe I can RMA it. It is just so unusual for just the sound to crap out.

Sorry I couldn't help.
Before you RMA the board, contact mfr. and see if a BIOS update might solve the problem.

ASUSTeK Computer Inc. -Support- Call Us

I know there's a newer bios available. Never updated it because everything was working ok. Will try that later today. Thanks for your help.

Good luck - let us know if it works out.

I tried to use the ASUS software to auto install the new bios. It didn't seem to work. I let it run for about 10 minutes and it seemed to be in a loop. Will do a straight download and manual install later today.

BIOS updates can be tricky.

I would call ASUS and let them guide you through it.

I did that and it solved a problem for me.

I've updated BIOS' before, they can be a little nerve racking to update. Never had one fail yet though. I will take your advice and call ASUS and let them help, couldn't hurt. It's been several years since I've done it.

I called ASUS...several times today. They suggested reset CMOS, done. No affect. Called again, they suggest I remove all Nvidia drivers, no affect. I'm assuming because they have not suggested I install the latest BIOS they feel that is not the problem. They at first believed it was a drive conflict but now when I plug in just the green audio plug on the motherboard I get a severe hum through the speakers. The tech said it might be a bad cap on the board. The Sabretooth has a 5 year warranty so I'm good if I need to RMA it. It's only two years old.

I still think it is a BIOS issue.

I would call again and request a walk-through on a BIOS update.

If that still fails, then an RMA would be your last option.

Sorry 'bout that.
