Hi, this is my first post so excuse me if this has been posted before but i just couldn't find the answer on the net.
I have an on board sis 7012 sound card, i can make it work with alsa and oss, and both drivers worked, but the problem is I cant control the volume, either is 0% or 100% no mather what i do. alsamixer wont let me increase or decrease the PCM, only on/off functions work. When i try OSS(i810_audio module) the same problem occurs.
Anyone has any hints to try?
Thanks in advance.

can you adjust volume in any other mixer? how about from other programs? what distro are you running? kernel? have you run the alsa config ..alsaconf.. and configured the card?

I tried other mixers(kmix,gamix,etc) but all do the same(either 0% or 100%). After compiling alsa, i run ./snddevices , alsaconfig and alsamixer to get the pcm up and down. Im running slackware 9.1, kernel 2.4.22. And i don't know want configuration to make, thats why i asked . I don't know why it doesn't work with alsa not OSS, I'm sure its my fault some how but i cant find out what I'm doing wrong here.

have a look at this

http://www.alsa-project.org/alsa-doc...odule=intel8x0

i noticed at the bottom of the page, in the tips section, that you may need the cvs version, for unknown reasons, to get the mixer working. there are several good tips at the bottom of the page.
good luck.

I feel you mate, I have the same problem with my SiS 7012 card. I went through the trouble of installing ALSA, and then running alsaconf, and the alsamixer. Both ran along great, and even set up my OSS Emulation. The result is that I can play xine, xmms or any other software that uses sound, but I can't change the damn volume!

I tried to download and install the "original" driver from SiS, but it didn't do me any good at all, i.e. no change in my situation. The funny thing is, I didn't need ALSA or anyhting else. Ever since I installed Redhat 9, the soundcard detected fine, the test sound played magnificently, but there's no way I can adjust the volume, and it's not mixer specific either (in other words, not one mixer works). Admittedly, however, the ALSA drivers are better. By the way, I used CVS to download and install ALSA, so it's pretty much the latest software.

It's a pity because the card works great on my Win 2K partition. Just happens to give me this nightmare in linux.

So if anyone can help, please, please, please!!!

Yes that is right, the cvs didn't do the trick either. Having the volume so loud is really starting to piss me off a little bit. By the way, using alsa and the eSound plugin in xmms the volume works fine but the sound if awful, sounds really really bad. but then again if that plugin made the pcm work maybe there is a hope.

Hello from Santiago de Chile!

I have the same card and i installed ALSA without problem. May be this little guide can i help you :

Step 1.
- First download alsa sources from http://www.alsa-project.org (alsa-driver, alsa-lib, alsa-utils, alsa-oss)

Step 2.
- unpack alsa-lib and compile. (./configure && make && make install)
- Compile alsa-oss (./configure && make && make install)

Step 3.
- Unpack alsa-driver
- ./configure --with-isapnp=no --with-sequencer=yes --with-oss=yes
- touch include/linux/workqueue.h
- make install
- run the ./snddevices script

Step 4.
-- Check if you have unresolved simbols with depmod -ae. If you get errors repeat step 3.

Step 5
-- run ldconfig

Step 6.
- unpack alsa-utils and compile. (./configure && make && make install)

Step 7
- run alsaconf ( here this must be configure your modules.conf )
- run alsamixer ( your channels are muted by default )
- run alsactl store

Step 8
- reboot
- cd /etc/init.d/alsasound start
- startx

Here my ALSA configuration in modules.conf

alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0
options snd-intel8x0 snd_ac97_clock=0 snd_enable=1 snd_index=0

Enjoy!
