so here we go. a small how to enable sound on the efika on Gentoo.

1. I'm using patched vanilla-sources (in contrast to efika-sources from the efika overlay):
now you should have 2.6.20.1 (as of today) in /usr/src/linux-2.6.20.1.

2. Grab the kernel patches from here (thanks crux people ;-) ) and patch the kernel:
3. grab my config and make your changes to the kernel:
4. compile the kernel
5. install the kernel
6. reboot into your new kernel
7. now you should have something like:
8. install alsa-utils
9. edit /etc/modules.d/alsa:
10. update /etc/modules.conf and /etc/modprobe.conf:
11. start alsasound and add it to the default runrevel:
12. use alsasound to unmute your channels:
NOTE: if you want use the optical output then unmute IEC958 and set IEC958 Playback AC97-SPSA to 0. I'm currently having much noise on the optical output and am trying to find a solution. A small note from you, if you have also noise would be helpful :-)

13. use your favorite app to play sound files. For example:

Following this guide, i successfully managed to get sound out of my Debian Etch, running on my Efika.

But the sound gets distorted, has hickups and other bad(tm) things, when the Efika accesses the hard disk, or it's busy with other tasks. Is this a known problem of the current AC97 support? Or i did something wrong? (I used vanilla 2.6.20.1 kernel, and applied the sven+cruxppc patches).

nice :-)
no, I do have the same problem: http://www.powerdeveloper.org/forums/vi ... php?t=1194

I just installed Debian on my Efika, with the kernel and modules found in efika.info
I thought that it would come with precompiled modules for sound and all, but after reading this, I started to think that it doesn't... At first I tried 'modprobe snd-via82xx' but it doesn't work ... ^^;

I didn't install Gentoo because compiling takes long times, and setting a cross-compiler environment is tiresome. On the otherhand, in previous comment I read that sound in Debian is buggy? :(

Some hints here, please ^^

SuSE is all binary, but at the moment it's not yet completely user friendly to install :-) Sound works nicely, except during software compilations, but (not that often) I have the same problem on a 1.9Ghz Centrino notebook as well...
I expect full EFIKA support in the next alpha version of 10.3 (due in about three weeks). You should try that.

Debian: you should try the kernel from http://people.debian.org/~luther/efika/ as it has it has sound support, as far as I can remember.
Disclaimer: I tried it long time ago, and can't provide instructions to update to that kernel, as I don't use Debian regularly...

Here are a few addons to your efika audio mini-tuturial :

You can also use "alsaconf" which auto-configures sound stuff (/etc/init.d/alsa file)

Also don't forget to add root & all users to the audio group or some apps might not work.
gpasswd -a root audio

Pieter is working on a new image we will release here. It will work.

R&B :)

I am reminded of a small errata with the 9766 codec;

http://www.idt.com/products/getDoc.cfm?docID=11105830

It seems under certain circumstances if the codec cannot get data reliably, it will hiccup. I wonder, are you using 48KHz for the output, or 44.1KHz? Can you upsample/downsample with better results?

The audio codec is currently completely CPU-driven with the current patches, something which a custom BestComm task for driving audio would probably solve. However this is a little more difficult than it sounds.

If anyone is willing to sit down and work on this for Linux (there is an MPC52xx Ethernet driver has a nice example of loading BestComm tasks, and an example task) that would be great.

I am actually sitting down here with 2.6.21 having a play around with patches. There are some basic missing features across the board I think need resolving.. I'm going to make a "TODO" list and put it under Platform Support. If anyone's willing to take up the challenge, we can accept projects (if you have a board already we can add a new one or use your own) and link them from that page for blog entries. It's basically just silly things like ethtool support, DMA for sound, maybe port the MPC52xx AC97 support to the 2.6.21 ALSA SoC framework (turn off the AC97 clock when not in use, perhaps?), an irda driver, maybe GPIO support for PSC6, or the UART, hdparm support for the hard disk (just so it actually works - it doesn't have to change any features, the ATA controller is quite restrictive) and a little more efficiency involved.

If anyone has any ideas for features people want to see in Linux (with the possible disappointment that nobody agrees with you, or nobody cares :) feel free to maybe add a thread here and list them. It would be great to know what is expected of driver support.

Why can't we get the Efika.info site UP TO DATE???

I just got my Efika a month or so ago, and just installed Debian and it runs great(BUT NO SOUND)!!!! Files are from 2006! Id just like to install an OS without all this patch this and change that! I wasted hours installing different version of gentoo and debian ! still no audio!

Can someone pleassssse get a Debian or Gentoo or ANY linux install with sound support posted on Efika.info! Or do I need to just buy an VIA machine for my car audio and put the EFIKA on hold for MorphOS(next 5 years?)! gezzz

ZXoney

In about a month openSUSE 10.3 will be released, with full EFIKA hardware support. You can test beta2 right now, please take a look at the openSUSE topic of this forum.

You can also get sound on Gentoo any time, as it's a source based distribution :-) See http://dev.gentoo.org/~nixnut/efika/

check this thread :

Hi, can PLEASE anybody write down a step-by-step guide how to enable sound on Efika in Debian etch linux for novice users (like I am)?

I have got OpenFirmware updated and I read this topic and also that topic completely but there is still no progress.

If you are a novice you may not have the skill required to actually get it to work. Compiling kernels, modules and fiddling with alsa configurations is not exactly "point and click".

A how-to guide written step-by-step would not give you any better advise than the forum posts already here, although I'd welcome someone building a kernel and module set for Debian that integrated the latest patches, and even a new Debian Installer build, like Sven used to do..

OK but can´t somebody who already done this put alsa configuration and compilled kernel and modules somewhere for download? I just ask and it is not because of beying lazy.

Or you suggest me to use SuSE instead of Debian? Is it any easier?

One more thing - sorry for my poor English

Has Sven left the building?
