sound & Linux

Josef Forman — Fri, 23 Jul 2004 02:53:30 GMT

Hi everybody,
what about music? I use SUSE 9.1 - I think it's really great distro, but when I'm playing music, time to time I hear some noise (something like old vinyl records). Previous version of distro was even worst.

anyone\anything can help me?

Hi,

Please, could you give us some more details?

What kind of software are you using to play music?

This happen always with the same software or with any other one?

Frank.

Hi AliG

I have had exactly same experience, I have expected the kernel 2.6 will a litle better for music than in the fact is (even if is much better than 2.4 as you mentioned)

Maybe it is already not kernel feature (I'm not familiar with kernel developping) but only codec issue.

I suggest to try another player , e.g noatun
I have better experience than xmms with it from 2.4.x kernel, maybe it will be same on 2.6.

hope this will help you

i've seen this problem on windows boxen when the grounding isn't proper.

check you power cables and wiring, and be sure your powersupply is actually grounding your case (because the pci mounting bracket is expected to be grounded).

Background noise can be caused if your soundcard is in a slot next to certain other adapter cards, or the computer and/or speakers are close to a device that generates noise. Have you tried comparing this using say dual boot into Windows?

Hi,
i think cables and all the wirings are correct. I use Toshiba notebook and under dual system (WinXP) is everything OK.

Problem is certainly not due to kernel, and probably not to XMMS, but more likely to the module you're using.

Could you post output from "lsmod" and "cat /etc/modules.conf" ?

Output of lsmod command is in attachments. But /etc/modules.conf seems to be zero size.

:) What an lsmod ! Did you compiled yourself or is this the Suse kernel ?

Nevermind, you seem to use OSS. I would try to use alsa instead : http://www.alsa-project.org/

Could you post output from "lspci -vv" ?

Regards,

Fred

Yea - my lsmod output is really modules mania :) I think is due to i use VMWARE (it brings a lot of modules).
Until now I thought, that i use ALSA, but now I see it look like i use old OSS.
lspci -vv...

Looks like you're having an "AC'97 Audio Controller". I already used a laptop with it and it went pretty good with the provided kernel module (ac97). Something like alias ac97 snd in modules.conf should help.

Before doing anything, just have a look at this page :

If your laptop is in, you'll probably find your solution.
