Another Sound Card Problem

kwigibo · 07-24-2002, 08:49 PM

Hi, I am having trouble with my onboard soundcard. I doesn't work in RH7.2 or Mandrake8.2. I got rid of RH7.2 so that doesn't matter anymore, in Mandy I get this error after rebooting.

Quote:

Sound Server Informational Message

Error while initializing the sound driver:
can't set requested samplingrate (requested rate 44100, got rate 0)

The sound server will continue, using the null output device

Any ideas on how to fix this? any help will be appreciated, oh and here is the output from lspci

PS I can't help to notice but there seems to be alot of soundcard problems lately, BTW I read other posts and no success there.

RedHat uses standard kernel modules whereas Mandrake uses ALSA. Yeah there have been a lot of sound issues lately, especially with these annoying cards that leave a lot of things up to emulation in the software, hence the existence of the AC97 Codec.

Anyway, I can't find an accurate list of alsa sound modules to figure out which one deals with via these days, so lets see what you have loaded this far. What's the output of lspci? There should be a good blob of them.

Cheers,

Finegan

Thanks for the quick reply, "lspci" is above in the first post here's "lsmod"

Thanks for correcting me... er... yeah, I mean to type lsmod... der...

Okay, from the looks of it, the thing didn't modprobe all of the alsa modules... I'm confused now. It seems to... no wait, I just checked and viaudio isn't a kernel module, so... its an alsa module, just one I've never dealt with... I wish I still had a Mandrake machine to fiddle with.

See if you have the normal 2.4.18 kernel module for the card: via82cxxx_audio.o.gz it'll be in /lib/modules/2.4.18-mdk-??/kernel/drivers/sound/

If so, try to rmmod viasound and modprobe that... This one is rather confusing.

From this goober's page that's gotta be the right normal kernel module: http://www.uwsg.iu.edu/hypermail/lin...03.1/0808.html

I take it of course that sndconfig hiccups on this one?

Cheers,

Finegan

Hi, I tried what you suggested finegan, below are my commands

after rebooting it goes back to the original. Did I misinterpret what you said or is my sound card just screwed?

thanks kwigibo

finegan · 07-27-2002, 10:19 PM

No it loaded alright, loaded cleanly from what I can tell too if it grabbed the codec module as a dependancy. Most importantly, with the kernel (NOT the alsa) modules, did you get sound? The via82cxxx whatever module will always read as un-used until you pipe something into the device... anything quick and dirty, probably the best test is a regular music CD and the command line player workbone, or just as good is whatever GUI CD player you have, probably KsCD.

Convincing Mandrake to stop loading the alsa modules at boot is step 2, and I'll have to figure that out again myself, its been a while since I went 4 rounds with Mandy.

Cheers,

Finegan

kwigibo · 07-28-2002, 03:01 AM

No I get no sound, the lsmod says that the via82cxxx_audio is still unused

thanks

finegan · 07-28-2002, 03:16 AM

Check /etc/modules and /etc/modules.conf and comment out all of the ALSA goop, then drop in the lines for the via82cxxx adapter. Pulling an rmmod followed by a modprobe at every boot is begging for an oops. I'm pretty sure that's how mandy handles it, I've got 9.0 beta1 on another partition, but my card is so wiggy that there are no alsa mods so Mandy installed kernel mods.

Cheers,

Finegan

kwigibo · 07-29-2002, 05:03 AM

Hey finegan, this is my modules and modules.conf files.
I added the line at the bottom of the modules.conf as you suggested, is this right? and also do add the same line to the modules file?

Code:

[root@localhost etc]# cat modules
# /etc/modules: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line.  Comments begin with
# a `#', and everything on the line after them are ignored.

[root@localhost etc]# cat modules.conf

alias usb-interface usb-uhci
#alias sound-slot-0 viaudio
alias sound-slot-0 via82cxxx_audio
[root@localhost etc]#

Thank you very much

Okay, just logged into my slack machine at home and mounted the Mandrake drive so I could take a look at this mysterious /etc/modules file that my Slackware trained brain ceased to understand. It seems that the only line you add there is the name of the module:

via82cxxx_audio

Post back if it still tries to forcefeed you some alsa.

Cheers,

Finegan

kwigibo · 08-02-2002, 10:09 PM

No it doesn't appear to but the sound card still isn't working. I only use it to play CD's when Im on the computer anyway, and that works if I plug the speakers into the headphone jack so I can live with that.

I really ... really appreciate all the help you have given me, I have learnt a lot. Thankyou
