Mic is USB? Set the mic on something like a rubber pad. Also, try wearing headphones, see if that helps. It sounds like you're dealing with normal feedback issues, and Windows' echo cancellation may simply be better than what you've got set up.

I took your suggestion and turned off all of the Capture settings on the X-Fi, obviously I had to leave it on the USB mic to get audio through. Still having the issue. My mixer settings for capture on the X-Fi are Master, PCM, Line-in, Mic and S/PDIF-in. Most of them had capture enabled, I disabled all of them. There doesn't appear to be an input setting. The lone mixer setting for my USB mic (AK5370) is mic, which is set to 100% and LR Capture. Everything seems pretty covered in there. -- Jason Weisberger jbdu...@gmail.com

There might also be a setting called "input" which can be set to i2c, i2s, mix, etc. Play with these. I had the same problem with a Soundblaster Live 24-bit, and the problem was that it was set "mix", which is a setting that allows you to record whatever is currently playing.

Yeah, correct me if I'm wrong, but those usually have built in echo cancellation. Most usb speaker/mic combos do. I believe I'm relying on software in my case.

Another option is to use a small USB sound device. My headphones came with one, for example. They can be really nice for reducing electrical noise in the capture channel, too. They also occasionally crop up where you might not expect them. I picked up an HP 'travel' USB hub some time back, and was surprised to discover it had a built-in NIC, mic input and stereo out. -- :wq

It's also possible to set this in KMix, but I don't know if you're using KDE.

You're thinking of echo cancellation. I'm sorry you are correct, I meant to say echo cancellation as in the subject. I cannot hear myself, the person on the other end can hear themselves.

> How are you listening to the audio? Headphones, speakers, telephone? I'm using speakers and an external usb microphone at the moment. As I said, this same setup works perfectly in Windows 7. I'm sure that if I were to connect a headset the issue would go away, but that still doesn't explain the problem. I have also tried the home phone thing, and while i think it's neat, I find it a bit pointless for me, I'm using Google Talk to save minutes on my cell phone plan.

Can you hear yourself through the speakers when talking into the microphone? If yes, that means you need to disable the loopback in alsamixer. Noise cancellation doesn't seem to work at all. Noise cancellation doesn't have anything to do with that. You're thinking of echo cancellation.

Headphones, speakers, telephone? The only way I've used googletalk is to have it call my home phone before dialing the other person, which works amazingly well. I've never tried using a microphone and speakers, though I've used Skype that way a few times without difficulty.
