Emu10k1 & Kernel 2.5.47

frenion · n00b Joined: 25 Nov 2002 Posts: 26

I am trying to get sound on kernel 2.4.47. It works beatilfully and all, with nvidia drivers, no problems there. I tried emerging emu10k1, but it gives me errors about the missing header emu_wrapper.h. Seems like kernel 2.5.47 doesn't have where it should be. Oh well.
Then I try to build OSS as a module in the kernel menuconfig. It compiles great, I load the module soundcore, works fine; then I load the module sound, works fine. ac97_codec works fine too. But then I try to load the emu10k1 module. Then it gives me an error:
/dev/mixer not found. Eh... Pretty strange. Building it into kernel didn't work for me either.
Then I try the ALSA emu10k1 drivers included in kernel 2.5.47. They install fine, and loads fine: But! I don't get any sound from my rear speakers, and I can't turn them up in the mixer. I have no Ogain. :(

I would like to hear from anyone using emu10k1 drivers on kernel 2.5, and how they made it work, and if they have any idea to how I can make it work, either by using OSS, ALSA or whatever. Or changing to another version of 2.5.

Thank you very much. :o)

[Disclaimer: Yes, I am aware that this is a development kernel, and things might not work. Please don't tell me again. You'd be person number foobar to do it. :P But I want to run it, don't try to talk me out of it, and if my computer explodes into 10000 tiny peices, it is my own bloody fault. :)]

Yeah Im running 2.5.47 at the moment and have seen on the mailing lists someone had a patch to get rivafb working again in the 2.5* series kernel but I havent been able to find it

, would be quite nice being able to make use of hardware accleration on the GF4 running directfb

,

Cheers

I don't know if the causes are comparable, but somewhere in the 2.5.30-2.5.50 line there seem to have been structural changes to the kernel-headers hierarchy.... I've read somewhere that this makes it impossible to use 3rd-party kernel drivers with them.

Indeed I can't have Alsa on 2.5.50, it won't compile because of some missing kernel headers (irq_vectors.h, etc).

Figured out how to make 4.1 speakers/EMU10k1 work with ALSA and kernel 2.5.x! Well, problem is, the ALSA/EMU10k1 volume control is too fucked up for general use. Anyone got a fix? :o(

How do you setup alsa when the alsa-modules are in the kernel anyway?
Do you still emerge alsa-driver / tools/ utils etc ?
How does one do this in general?

Usually if you can't get sound working in 2.5 after building and loading all the alsa-style modules, you need to build the oss compatibility modules as well (snd-oss-mixer and snd-oss-pcm).

My only problem with alsa/emu10k1 under 2.5 series kernels is volume appears to be totally forked. I can run say aumix (which I believe is calling the oss layer) but changes to it do not affect the actual volume.
