Ok. If it doesn't work with Lenovo drivers, it isn't going to work.

BUT...

I have one more item to try. Check the BIOS for Audio options. These should be under Configuration. There may be an option to select which type of audio to use. There may be an option for audio type Auto, HD or Legacy. If it's there, make sure it's set to HD. The option name may vary from OEM to OEM but it should have something similar.

Yes, I tired it with this video 2.1 Speaker System Test - YouTube and everything works fine (even the sub), but I think I fixed the problem.

Everything works because I was comparing my home theater sub woofer (800W)to my small sub(4Watts).

I was only wondering about not showing 2.1 audio channel.

Actually, your sub is 4 Watts. The satellite speakers are 1.5W each for a total of 7 Watts.

In any case, I glad you fixed the problem.

Did you ever find out why the 2.1 audio channel was not showing?

My system doesn't show it either. The only options are Stereo, Quadraphonic, 5.1 Surround, and 7.1 Surround. The XP computer that this PC replaced had the option for 2.1, but this Windows 7 system does not.

I currently have it set on Stereo and tried the Speaker System Test you referenced. Any signal sent to the sub-woofer is also heard on the stereo speakers - so I wouldn't say everything works here. If YouTube only supports 2-channel stereo sound, that could explain sub-woofer sound being heard from the stereo speakers but not necessarily. Any suggestions for how to test this?

Also, I had the Realtek HD Audio Manager window open when I started trying to troubleshoot this but now I can't seem to find it. I'm referring to the one shown in the 1st reply in this thread. Can anyone tell me how to get back to the Realtek HD Audio Manager window?

I realize this is a very old thread, but it really seems to fit the issue I'm facing. Thanks in advance for any help!
