Hi, I'm using a dual USB iBook running Gentoo w/2.4.24-benh0. I cannot, for life of me, get sound running on my computer. Well, not when I want to (more on that later).

I have PowerMac DMA support built-in, OSS built-in, and I2C built-in. I have pbbuttonsd configured with my mixer as /dev/mixer which exists.

I've followed the FAQ and searched and followed things that are pertinent. I'm a complete sound noob so if I haven't posted the right things, let me know and I will gladly get them.

Oh, for the sound when I don't want it. At random intervals, I get blasted with loud static that will not go away unless I put the iBook to sleep.

I really need help as nothing I've tried works.

<edit>I also have /dev/dsp: No such device or address when running quake2 and a similar error when running XMMS</edit>

I have dmsound_pmac compiled in the kernel not as a module, so when I run modprobe it can't locate the module. Should it be a module instead of compiled in?

Well, it should work compiled in too...
Do you have aumix in /etc/init.d/ ?
It's a good thing to emerge and add to your default runlevel.

Did you edit your kernel config much, remove stuff you didn't think you'd need etc? If so, you could try to compile a kernel with the default config.

And btw, ppc-development-sources are great!

I do not have aumix, I am emerging that right now and I will add it to my default run-level. I have edited my kern config quite a bit but I read the help on everything I wasn't sure on. Could there be a problem there? Potentially, but everything is in that the documentation said should be in from where I sit.

I will edit this post with my results once emerge aumix completes. Thanks for your help.

---
Results: failure to configure aumix at boot. I do not know where to find that particular error. The pertinent portion of the dmesg is as follows:
...

Audio jack unplugged, enabling speakers
BA-Init tumber mixer
PowerMac Tumbler DMA sound driver rev 016 installed
Core driver edition 01.06 : PowerMac Built-in Sound drive
Write will use 4 framgents of 32768 bytes as default
...

It goes into APM information after than and so and so forth.

No ideas? I'm perfectly willing to provide the required information if I haven't included it.

try dmasound_pmac as a module. Works fine here. Never tried to get it working compiled in.
[edit] or try 2.6.x kernel.
Alsa is a bit buggy with me. But dmasound_pmac works great. Even the mic-in works. If you want to use with arts you have to configure the server to run with "low sound quality" to have it working, though.

I don't think you need to build OSS into your kernel for this driver. It works for me fine without it, anyway :)
