[SOLVED] 3.15.5 Kernel No Sound

[shoober420]

Does OSS4.2 work with the 3.15 kernel? I recently updated my 3.14 kernel to 3.14.10, and my OSS stopped working.

Works for me.

Did you use the 2009 build from the website, or the package from Arch Linux? What if I compile the new 3.16 kernel, do you think it would run with OSS4.2 if I use the 3.14 compatibility patch?

[nuc]

Of course I use it with the 3.14 patch (it's integrated in the Arch package). I have no idea if it works for linux 3.16 (it's not even released yet...) that's a matter of luck.

I can't get any sound when using the 3.15.5 kernel. Strangely, my spdif-out.enable keeps reverting back to "ON." These are my results when running a osstest.

Code: Select all

I can't seem to disable SPDIF, everytime I turn it off, it turns back on.

Did you also update your kernel-headers to 3.15?

[shoober420]

Yes. I think the Arch packages differ from the ones available from the developers site. Thats why I asked you which ones you installed. I think the Arch packages might make new patches for each kernel release. Are you using the 3.15.5 kernel? I'm currently using 3.14 till I figure out why I have no sound.

[nuc]

No, arch doesn't use any additional patches apart from the 3.14 one. I use kernel 3.15 and it works just fine.
I have no idea why it doesn't work for you... you will probably need to wait for somebody else to help you.

What happens when you run "sudo soundon" (if already enabled run "soundoff" first)? Whats the output? You may need to wait a bit.

It tells me that OSS has started, or is already running. The funny thing is, I hear the destinctive clicking noise when the OSS module starts when I boot my machine (maybe it only does this for me). I think it might be a kernel patch that I'm compile with my kernel build. Its the BFS patch (Brain Fuck Schedualer). I'm going to compile the kernel without BFS and see if it fixes the problem. It also might be because I set buffer overflow detection to "strong" for one of the kernel options. I will have to test all these and find out.

Last time I looked threw the Arch packages, there was an option for OSS git builds. That's really cool. I was about to go with Arch Linux, but Steam was designed with a Debian based distro. Steam is just more compatible with Debain and Debian based distros. I would think there's a possibility that Arch compiles there own OSS builds and even includes there own patches with them.

EDIT:

I found out what it was. It was an option I chose during compile. Just so no one runs into this problem as well, I will mention what option it was. The "Stack Protector buffer overflow detection" setting is what did it. Its under "General setup." I'm not sure if setting it to "Regular" will do the same thing, but I wouldn't try it. Setting that option to "Strong" for sure will prevent OSS from playing back any sound and give errors. Just a heads up.
