I am having issues with my sound under Red Hat 7.3. KDE or GNOME

Intel MB with Yamaha Sound built in ( OPL3-SA3 ) Which is on the supported list. I get the error when it boots up that the device is null. I went in chmod to 777 just to be sure. Sound works just fine when I put Windows back in. I have used sndconfig but that has not helped. I have read a bunch of other threads but nothing so far has helped out my issue.

Please help....Linux Newbie

what is the error?

did you try to set the volume with aumix

Here is the info you requested.

Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device.


[root@localhost root]# aumix
aumix: error opening mixer

[root@localhost root]# cd /
[root@localhost /]# aumix
aumix: error opening mixer
[root@localhost /]#

Thanks

the problem / answer is more than likely going to be in modules.conf / kernel params

try this

http://www.linuxvalley.it/encycloped...sound/OPL3-SA2

I'll look at it & try it out....

I will let you know the outcome.

Thanks

Well I have messed around with that doc but a little over my head. I disabled the built in sound in the bios & restarted the machine. It reconfigured with out the sound. Then I went back in and enabled the sound & restarted the machine & still get the same error....

Here is an excerpt from var/log/messages

I have gone in to sndconfig & set it to the paramerters that I see in the messages. That did not help either.


Unable To Play Audio

I hope that this may give more light on my prob & help with some more advice.

Now lsmod looks diff...

Thanks

Well the update on my prob....

I did not have the patience to work thru the issue so I went & bought a SoundBlaster card, disabled my onboard sound and bingo it works like it is supposed to.

Thanks for the effort.

please help me out!!
i have the same problem!!!


thanx!

I was not able to make any dents in the progress of trying to get the onboard sound(The motherboard is from 1997 & we know that is about 20 computer years old) to work. I went and bought a Soundbblaster 128 pci. I disabled my onboard sound in the bios. Loaded up Redhat 7.3 & disconfigured the bad sound card. Shut down the machine & installed the new card. When RH7.3 started up it detected the new card & set it up. No problems!

I do not know if this is the help you were looking for but this is all I did.

With RH 7.3 all the systems I installed came up with sound working.

If your card is supported in Linux then it may require a kernel patch or rebuild.

I went and looked at that link you sent & messed around a bit but was a little more then I felt comfortable doing at this time. I am just inthe stage of trying Linux out to see if I can get over my MS dependancy. So I wanted it to be more of an easy process. In the future I may go back & see if I can get the onboard sound to work, but for now i just wanted it to be "easy". And it was.

Thank you.

how to disconfigure!??

When I went into the bios I disabled the sound & I left the new one out. I booted up RH 7.3 and when it came to the point of detecting new hardware it told me that the onboard sound was gone & if I wanted to unconfigure the changes...I did so & then let the machine go all the way to KDE. Then I shut the machine down & installed the new card.

I did not have to go in & monkey with anything on a command line or anything. It was all automated.

I hope that helps. If you need more explanation on a specific step that I did then let me know.
