AC97, Chirping from Speakers


Hello all.

I've successfully installed Debian and MythTV, but I'm having a lot of difficulty with my sound.

I've searched other threads and seen other people with similar problems, but haven't really found a solution.

Here's output from lsmod:

I can control the volume with aumix, but the sound of the chirping goes up and down with the Volume or PCM sliders, and none of the other sliders has any effect.

Any help you can provide would be greatly appreciated. Thanks.

Hey I am pretty new to Linux, but I'm also using Debian and an AC97 Soundcard and I also have a "chirping" from speakers. I guess it is because it is not a professional soundcard and thus overdrives fast.
I use kmix to remove it as good as possible, and it should work for you too. Just grab an audio file and put PCM down until you don't hear any chirping. Worked for me, although you wrote that it seems not to work for you.

Edit: Ok I listened exactly to the sound and although it gets better the clipping never disappears. In Windows it works, strange. Maybe we need some kind of limiter or so?

I'm not sure, but I had something weird happen. I was getting the chirping from the command line and with Gnome loaded.

However, I loaded up KDE and it started working!

No idea how KDE could've fixed the problem, but somehow it did.

Try loading up KDE and see if this works for you.
