trying to fix sound onboard system
Hi,
Still have not found any solution to my sound problem !! The onboard via 8233 a sound system is mute except for cd ( i can have sound from kscd ) the bell is ok too, but anything else is not. Alsa came with mdk 9.2 and i changed modules to match my soundcard requirements ( via82xx ). Soundcard is detected, i have no strange messages and i even have a loud sound from the speackers at boot. Every mixer is 100 %. I chmod /dev/dsp .... and add myself to the audio group. I use Kde and disabled arts ,as this one was not happy and send me error messages. I cannot play any wav sound with Totem or Xmms ( and yes, files are associated !! ) Can anybody with the same problem ( if somebody solved the problem it will be great !! ) give me a reply. |
One thing comes to mind:
XMMS or Totem may still be trying to output sound to arts, which you've disabled. Check the output preferences for them, and change them to OSS/ALSA (whichever you're using). Might help.... might have already done that... Are you getting any error messages at all? Check dmesg? --Rounan |
Thanks Rounan for the reply,
I only have OSS as output, cannot select anything else !! I suppose Alsa can emulate Oss, so i also suppose sound should be there... but maybe i'm wrong. No strange messages dmesg ok too. |
Check mixer channels, make sure they're not muted?
Sorry man, I'm at a loss. If there aren't any error messages, outputs are OK, and still no sound.... no idea. :( |
Thanks Rounan for your reply,
Taking the problem back to the root, i discovered a problem. Alsa ask to chmod /dev/dsp /dev/mixer ... etc I discovered that those were only links to /dev/sound/dsp ... /dev/sound/mixer and so on !!! So i tried to chmod the above to 777 to be sure, the thing works but if i log in and out... things get back to the previous information!!! Can i store chmod information and how ?? ( i use Mdk 9.2 and i used mdk control panel to change things but i discovered this was not changing much ). I have used command line to chmod with the above result. Also do you know if i should change group ( from users to audio maybe ?? ) Thanks |
Yeah, something must be resetting permissions at reboot, likely an alsa script.
The permissions should be rw for group audio, though, so if you do: adduser (you) audio it should give you access all the time. And to clarify: you're not "changing" group - one user can be a member of multiple permission groups at the same time. you're just adding yourself to the audio group as well. --Rounan |
thanks again for all the information.
I know about permissions, the only think is not clear enough is : If i use" ls" command for /dev/sound/dsp i have the following information ( more or less ) crw------- 1 myself audio ... The thing is ... should i change audio to users, or keep it as it is? Any idea where that script can be ( i have had a look but cannot find it ) Also, even when chmoding the sound was not there anyway ( the idea is should i have permissions right away after chmoding, or after a log in/ log out ? in that case as permissions are back to rw only for owner i cannot have sound anyway ? ) Thanks again |
You may be able to keep your settings by doing the chmod in etc/rcd/rclocal .this may run the chmod script after everything else initialises . Ihave not tried this with chmod but it works for my joystick . best of luck

Thanks both of you !
i changed modules and now everything works ( don't ask how i did it ) |
Hi,
I'm a complete newbie (Linux installed a week ago), and had exactly the same problem with my system which is VIA8233. I had CD playing, and the line input worked. All inputs were set to max and un-muted. As the CD, line, and speakers worked, I figured that this meant the sound card and its driver were sort of OK, but it wouldn't play anything from xmms, and although I had enabled all sounds, they didn't work either. I tried playing a wav file in xmms (I used startup.wav) and set it to 'repeat'. At first it wouldn't even play the file until I fiddled about with the device it used which was 'PCM'. Then it was playing but still no output. I then realised that in my troubleshooting I now had 3 mixers installed - alsamix, aumix, and KMix. As I am using KDE I decided to keep KMix and get rid of the other 2. After a restart (sorry - old Windoze habits die hard), it all came up and worked OK. Arts still seems to be starting and is also OK. I didn't need to fiddle with any permissions etc, and don't understand what went on yet, but I'm still learning! :scratch: Hope this may help others. |
hello, I have the same problem with via8233, I'm not a total newbie, but I have never configured a sound card, so it is a problem for me.
Bravofoxtoruk, I will try your advise. What do you mean with the PCM device? What should I set there? bibilit, how did you changed the modules? Is there some generous way how to configure via8233 sound codecs? Does someone in Mandrake team know about this problem? Thanks |
Hi,
Sorry to keep you waiting, quite busy!! Try first MDK control center and try to change from via module (via-82xx), to oss one (82cxxx) don't quite sure but similar. Log out and in and try again. You probably will have to change modules.conf file ( /etc/modules.conf ) to get things working. I explain recently how i did it in another thread ( seek for bibilit on this forum ) i hope you will get your answers. |
Something I came across while researching a totally unrelated topic:
Apparently, support for the VIA8233 was working in kernel 2.4.16, then "disappeared" until 2.4.20, when it came back. Check your kernel versions with: uname -r I'd suggest upgrading to the latest 2.4 kernel, or the 2.6 series if you feel ambitious. --Rounan |
