Hi. My problem is that sound is of bad quality. I mean, I have no problem whatsoever in reproducing sound, but it is of bad quality. It's not that it's awful, but it's like the treble gets too easily distorted, and isn't fixable with equalizing. It is bareable when I'm using the speakers (2 speaker classical system), but whenever I plug in my headphones, it is unlistenable.

I know it isn't a problem of my speakers or headphones because I had Windows XP installed a few weeks ago and sound was crystal clear. With Ubuntu I didn't have any problems either, but now with Fedora Core 6 it is really sucky.

So, on to the specs:

Vendor: nVidia Corporation
Model: MCP2S AC'97 Audio Controller
Module: snd-intel8x0

Kernel version: 2.6.19-1.2895.fc6. I use KDE.

Motherboard: K7N2 Delta2 (sound is onboard)

I've tried messing with KMix, to no avail.

So I'm guessing the drivers aren't that cool, or something like that. The problem is, I have absolutely no idea how to change a driver in Linux, and no idea where to find drivers, or which ones are the best, or even how the whole thing works. So any help is appreciated.

Thanks a lot.

EDIT: Also tried disabling "External Amplifier" on KMix, didn't work. And using modinfo and modprobe gives me a command not found... I'm looking for a way to install that.

EDIT2:

is what lshw (had to run it in root for it to work) gives me out.

intel8x0 is indicated for this soundcard
No-one else seems to be reporting this kind of problem with this card/driver combination. However, have you seen: http://forums.fedoraforum.org/showthread.php?t=97434 ... could be related, will certainly help you understand what is going on.

The data you want to give is from lspci (there is a verbose mode to get extra information too).

lspci | grep audio

modinfo and modprobe are available in fedora.

whereis modprobe
whereis modinfo

Issuing modprobe at a user prompt should just get you usage information. If these utilities are not present, then it would appear there is something wrong with your installation. Look for messages associated with your soundcard in the syslog. Also check fedoras sound setup dialogs for driver options etc.

Did you install FC6 from scratch or did you upgrade from an earlier version?
Have you updated it since installing?

Have you seen the FC6 FAQ (www.fedorafaq.org)

Well, actually I've solved the problem! It was something as simple as PCM volume too high. I continued on reading advices and solutions to sound problems on the net and I found that. It worked. It said "use PCM volume at 75% tops", and I had it at 100%. I changed it and it worked perfectly.

Anyway, thank you very much for your answer, it has nevertheless helped me understand a little more of how to do some troubleshooting with Linux.

Cheers!

well done - it always seems like such a lot of work to discover something so simple doesn't it?
