Computer isn't detecting audio devices

November 5, 2010 at 14:17:43
Specs: Windows 7 64
I was having an issue before where my sound was only being played through my subwoofer, with nothing coming out of my speakers (headset worked fine). In an attempt to fix that problem, I updated my audio drivers (onboard sound, M4A79T Deluxe). Now my computer isn't detecting any type of audio device I plug in, regardless of the port. I tried uninstalling the new drivers and reinstalling the previous version, but to no avail.

Edit: I'm using Realtek AC97 Audio

Do you see the Realtek sound manager in the tray by the clock. Orange speaker.

Open that program and configure the sound ports. You need to choose what you are using the port for. Most common configuration is line out to sub in the Green port.

Also check the Windows sound Icon, also in the tray. Windows has a habit of muting the sound when drivers are installed.

That icon was present before I reinstalled the drives the first time, but hasn't been since. I tried going through the Realtek folder to try and open it, but nothing in there seems to open it up.

You probably didn't install the correct drivers then.

According to the specs on your board you have ACL1200 sound chip. Look at the link below.

I uninstalled the updated drivers and installed the ones from the disc that came with my mobo, and am still having this issue.

I got a new soundcard and put it in, and now I don't have that issue anymore. But I'm back to square one where audio is only being played through my subwoofer, and not my speakers. In the Realtek HD Sound Manager all of my back panel sound ports are grayed out, only the front panel ports are highlighted. I tried plugging my speakers into the front panel and testing various options, but no sound comes out at all unless I have it set to headphones.

The soundcard I bought was just a cheap Rocketfish for $30 (5.1). My speakers are 2.1. Plugging the speakers into the soundcard I still get the same problem.

Go to the link below and look at the front panel sound update. The manual may be wrong and there is a correction. Also, the sound drivers there are probably newer. There wouldn't be a newer file if there wasn't a problem with the older drivers.

Alright, I installed the new drivers from the site, but my sound still isn't working properly.

Did you use the Realtek control panel to configure the sound ports (jacks)?

The whole back panel is grayed out, I can only manage the front panel port. And cycling through the different settings with the speakers plugged into the front panel I either get no audio or the same problem.

You need to review your motherboard manual.

First of all look a 3-22 in your manual concerning sound settings in the BIOS. Also 4-4.

Do you have 2.1 speakers? That would be a sub with left and right satellite speakers.
If the satellites connect to the sub then plug the sub cable into the Green port and set for line out.

I know you said you can't select any ports. Go into the BIOS screens by tapping Del at start up. Set like it shows on 3-22 of your manual. 4-4 shows the sound manager for Vista. I don't know if it is the same for Windows 7 64 bit.
