Hello everyone,

When I play any sound in slackware 9.1 My speakers make a "buzing" noise which is not present when I use the same sound or song in XP.

I have a VIA P4PB motherboard with onboard audio

Any ideas?

Thanks in advance all.

Do "lspci -vv" as root and post the info about the multimedia audio controller.

Thanks Aussie,

here is the info:

00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio Controller (rev 50)
Subsystem: VIA Technologies, Inc.: Unknown device b003

Ok, thats a standard via audio chip, next thing to do is see if the kernel module for it has been loaded.
Do "lsmod" and look for via82cxxx_audio, if it's not there load it with "modprobe via82cxxx_audio"

Ok here's the out put,

does this cout:

when I try to modprobe via82cxxx_audio i get errors:

/lib/modules/2.4.22/kernel/drivers/sound/via82cxxx_audio.o.gz: init_module: No such device
/lib/modules/2.4.22/kernel/drivers/sound/via82cxxx_audio.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.22/kernel/drivers/sound/via82cxxx_audio.o.gz: insmod /lib/modules/2.4.22/kernel/drivers/sound/via82cxxx_audio.o.gz failed
/lib/modules/2.4.22/kernel/drivers/sound/via82cxxx_audio.o.gz: insmod via82cxxx_audio failed

When I installed my video card i had to use:

modprobe agpgart agp_try_unsupported=1

Is there anything like that because they were the same errors I had when trying to get agpgart to install. Thank for your help Aussie

No, your using alsa, you have module snd-via82xx loaded already.
Have a look at the alsa page for via82xx chips.

Just for everyone's future troubleshooting ease the problem was fixed by adding:

OR
to the modules.conf file.

Thanks for the link that made my music sound normal again, Aussie!

Rockin And Rollin again,
