so are youre mixers unmuted?

schorsch79 · n00b Joined: 05 Jun 2003 Posts: 27

yes, they are unmuted. i did it like in the example. i checked this even with kmix.

when i try to play a sound with kaboodle it crashes, when i select the wav file and click ok.

no other ideas?

there's only one strange thing: when i open alsamixer, there is written:

after trying various things, i still can hear no sound from this speakers!

i checked:
- kernel config (soundcore is module, no kernel sound cards activated, APM disabled, ACPI activated)
- recompiled kernel
- rekompiled alsa-driver, alsa-lib, alsa-utils, alsa-oss, alsa-tools
- checked lsmod (the modules are loaded)
- checked dmesg (nothing unusual)
- kernel parameter pci=noacpi doesn't change anything
- everything is unmuted

if i do a

I have some bad news for you...

I have the same motherboard...

And I found out that the ALSA driver is most probably broken for it...

When I installed RedHat I found out that RedHat used the in kernel OSS driver and it worked like a charm!

When I enabled the OSS driver in my gentoo setup, it worked fine too.

Good luck,
drz

NOTE: The Sound chip on this board, doesn't seem to suffer from line-noise like many other onboard sound thingies...

thanks to Smoke2firE and drz for your hints. i too was about to buy a cheap sound card as a solution to my problem. i've tried with knoppix to make sure it's not a gentoo problem. then i changed the hard disk and installed win98 just to make sure that the sound works in windows. then i found - surprisingly - linux drivers on the install cd of the motherboard and as well on vias homepage. but they are all for redhats, suses or mandrakes... tomorrow i'll try to get the sound working with these drivers.

to drz: let me know how i could get the oss drivers, just in case. thanks!

uhm,

Well maybe I used the wrong term... (i think their officiaal called OSS Lite, though i'm not sure), anyway I ment the in kernel drivers...

If you compiled your own kernel you can enabled them in the "Sound Support" section. The Via chip is listed there somewhere...

L8er,

Hi,
I've got a laptop with this sound card, and after few months, (I tried on Knoppix with no success)
my sound card works fine now with alsa 0.9.8.
Have you tried this version???

schorsch79 · n00b Joined: 05 Jun 2003 Posts: 27

to drz:
ok, i'll try that, however i think there's only a via82cxx driver set (the "C" is the point). you mean that, right?

to PaRaNo:
yes, i tried the newest version from the alsa-project page without success.

i'll see what i can do later, because i can't access the computer right now. however, i'll let you know!

well, i'm not sure what the exact driver name is... but you could well be right about that...

regards,

to drz: kernel drivers are not working! there's only one via module and that's the via82cxxx driver. according to my informations, the c series and the 82xx merged (at least in alsa) and there's now only one driver, the via82xx. according to this the kernel driver is quite old and my board is new.

but finally: good news!

the via drivers viaudiocombo-2.3-1.tar.gz from www.viarena.com are working after some hick hack. by analyzing the src.rpm in the archive (with mc) i could extract files out of it, compile them and a file is created in /etc/init.d/viasound. i copied the viaudiocombo.o file in the modules directory /lib/modules/2.4.20-gentoo-r8/kernel/drivers/sound/ and removed the /etc/init.d/alsa file. i created a file /etc/modules.d/viaaudio with only one line inside

update: i found out, that the via 82cxxx kernel drivers are also required i.e. as modules.

So could someone make an ebuild to automate this?

or at least a step by step HOWTO?

I just had a similar experience with VIA VT8233 onboard sound. I was using the gentoo-source 2.4.20-r9 kernel, and I couldn't get sound with any module selections. I changed over to the gentoo-sources 2.4.22-r2 kernel and the sound worked without a problem. Must be a bug with the driver in the earlier version of the kernel.
