One audio channel is fuzzy/distorted, other is fine

One of my audio channels - the left one, I think - is fuzzy and barely recognizable, while the other channel is fine. I determined that it's a software problem by unplugging my amp and plugging earphones directly into the audio jack, and seeing that the problem persisted.

I've had this issue before, but after fiddling with a bunch of settings, I finally stumbled upon an option the Realktek HD audio driver gives you: when you plug something into the audio jack, a little dialog appears asking whether you just plugged in speakers, or headphones. If I selected headphones instead of speakers (regardless of what was actually plugged in) the fuzzy channel would pop back, good as new. But if I selected speakers, one channel would be fuzzy again.

The problem is: I want to play a video game that (for some unfathomably silly reason) doesn't work right if Realtek drivers are being used. So I uninstalled Realtek, and ordered Windows to install the default drivers, which it did. But now one channel is fuzzy again, and I can't find a Windows option similar to what Realtek gave me that fixes it. Or any option that fixes it.

So my question is: is there a fix, a workaround, or a different, reliable sound driver which allows you to switch between "speakers mode" and "headphones mode"?

The game maybe crashing because the sampling rate is set too high. Open your sound properties within the Control Panel choose your Realtek sound driver and click properties. On the Advanced tab you can choose the Default Format. Try the lowest 16bit 44100hz.

As for the distortion – perhaps your speakers has a loose connection.

Thanks, I'll try adjusting the sample rate.

The distortion is a software problem, as I said - the moment I changed the output mode from "speakers" to "headphones" in Realtek my sound was flawless.

According to your specs this is a desktop. Do you have both the front panel headphone jack and the rear panel audio jacks? Have you tried both, with the RealTek installed?

This is an old board (Intel lists it as a 2008 and only XP compatible). It may be better to go with an added sound card.

Only the rear jacks are connected. I've wanted to connect the front panel since I got the thing, but I never got round to finding out how. I think a sound card is a good idea in any case. And yes, I'm looong overdue for a total system upgrade.

But even when I had XP on this same rig, one of the channels was fuzzy. Which makes me think it ISN'T a software problem: surely XP and 7 use different drivers, yet I had this issue on both OS's with unchanging hardware.

May not be a software problem. The Realtek audio chip will use different amplification with headphones due to the different impedances when compared to line level (your speakers). It’s possible the line level portion of your audio chip is pooched. If you can’t solve your gaming problem by adjusting the sampling rates, then I would have to agree with fireberd and look into a separate sound card.

I just tested it on the Windows default driver with the lowest sample rate, and the game still blacks out - something else is wrong. I think I'll pick up a proper sound card ASAP, and further my searches into getting the game to work.

Thanks for everyone's input. :)
