Open Sound System

Hi!

I am trying to get the OSS soundsystem working for my nforce2 mainboard since
yesterday, but with mixed success. The OSS driver is generally setup
correctly and working, which means osstest outputs the demosound.

My problem now seems to be the devfs, because I am trying to apply the ruleset
to the audio devices in /dev, so that a normal user can access the sound in
KDE.

I used the following code for /etc/devfs.rules (which are given in this forum thread):



The ruleset should be processed by the oss.sh startscript by calling:



but this command only outputs:



and nothing happens to the device nodes in /dev. I already tried to play
around with devfs & devfs.rules, but whatever I tried, either it only gives
the above error message, or simply gives no feedback and does nothing.

If I run "/etc/rc.d/devfs restart", nothing happens.
If I run "devfs ruleset 200 && devfs rule applyset" no feedback, and no change
in /dev.

I tried a similar approach for changing ownership and perms for /dev/acd* with
another ruleset, I found on this mailinglist, but exactly the same result.

For some reason unknown to me, devfs seems not be working on my system. I did
nothing special on this installation. Installed from the 6.0-RELEASE
install-cd, updated world to 6.1-PRERELEASE, installed the latest OSS driver
package, configured it for nforce2, osstest OK, installed KDE by ports, and
now I am stuck to get sound working in KDE...

Any comments?

This is because after adding the rules to /etc/devfs.rules, devfs need to be restarted so that it reparses the rulesets. That error message is saying that it knows nothing of the ruleset (200) you specified. After adding the rules to /etc/devfs.rules you must run as root: It will not give any feedback when it is restarted, it will just reparse the rulesets, etc.

After devfs is restarted, the ruleset must be applied. This is done by the oss.sh script. The ruleset should only be applied after OSS is started because the device nodes need to exist before applying the rules.

Hopefully that helps.
