I just bought a C920 expressly for the purpose of recording live piano music for YouTube, and the audio is horrible....'scatchy' is a very mild way to put it. I called tech support and of course he blamed it on my computer. I've tried two different laptops and the results are the same.
I would really appreciate some comments or suggestions as to where the problem is here. I know that some will tell me to get a separate high quality mic for this use, but it's so bad I don't believe Logitech would put it out under this condition.

Since I first posted this I've been trying to find where the problem lies. As a result of testing, I conclude that the mic on the C920 needs an attenuator to cut its output back a few DBs. I have the input level set to 10 and it's still peaking frequently.
I also found that it was necessary to disable the built-in mic on the computer. Even though the C920 was set to be the default mic, the other was still putting in its two cents worth. Not sure I understand why; I assumed that the default mic would be the only one whose input was accepted.
I'll continue experimenting and post anything that will shed some light on the problem.

I can confirm that very "scratchy" quality and it was confirmed by another C920 user to me (actually he was the one that brought it up). It even starts when I only hold the camera in front of a small satellite speaker with normal volume playing music.
Even $2 mics take back dB a bit when the input volume is too high, like loud music, slamming doors, etc. This $100 camera doesnt do that.
You can counter it a little by lowering the input volume manually and turning on RightSound, but then the audio is too low in most cases and stereo effects are not there anymore, and, as bigdud already mentioned, it still peaks after that quite often.
That is pathetic to say the least.
I hope this can and will be fixed by a driver update, because I am really getting sick with Logitech "quality" and "support".
But seeing that the driver hasnt been updated since January, even though there are many huge issues, I dont have high hopes.

Similar problem here with the scratchy audio, this is not what I expected out of a high-end webcam from what I had considered to be a quality brand.
I second the need for a driver update.

Have just unpacked my c920 webcam for live Viberaphone recording and it is totally unusable for this purpose due to the scratchy audio. Very dissapointed. I do not suppose there is a workaround out there judging from the other posts but perhaps someone has a solution. Please let me know.

I had the same problem and I was not happy. However, this is what I did to fix my problem.
1. I installed all the software and drivers.
2. Removed the camera.
3. Cleaned the registry, ccleaner is free and fully functional, any registry cleaner should do.
4. Shut down and restarted windows.
5. Once up and running, make sure that every piece of software / application that might be using a mic or camera is shutdown, and I mean everything. I my case that was Skype.
6. Plug in the camera.
7. Go to the Logitech website and downloaded the software for your OS (Win7 in my case).
8. Install the software.
9. Update every piece of software / application that might be using a mic and camera.
10. Restart the software you are using and it should be working.
I did have Skype running when I was first installing the software and I suspect that this might have caused my problem and when I was updating the Logitech software windows indicated that there was a new update for Skype.
I hope this helps.
