Arch Linux

note that audio playback works fine.

I was very hopeful when reading this mailing list thread:

http://archlinux.org/pipermail/arch-dev-public/2008-April/005902.html

But nothing has happened so far. I am pretty sure that the 1.0.16 ALSA driver fixes this, but when trying to compile the alsa-project.org driver, it fails for my kernel 2.6.25. Searching the internet shows that this is a known problem, supposedly not fixed yet.

Cheers,
Martin

Doesn't 2.6.25 already have alsa 1.0.16rc2 ? (cat /proc/asound/version)
Though there are still several changes between rc2 and final :
http://www.alsa-project.org/main/index.php/Changes_v1.0.16rc2_v1.0.16#Changelog_between_1.0.16rc2_and_1.0.16_releases

But otherwise, I always had the same problem with my laptop, mic not working. The trick for me was to use model=hp option, but maybe other models could work too.
So my suggestion would be to experiment with several other models.
You can have a short list here : http://alsa.opensrc.org/index.php/Hda
more complete (maybe full) list for 2.6.24 :
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/sound/alsa/ALSA-Configuration.txt;h=4b48c2e82c3c1f340cf4cd7b4247d6d58941d162;hb=49914084e797530d9baaf51df9eda77babc98fa8
and for current git kernel version :
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/sound/alsa/ALSA-Configuration.txt;hb=HEAD

depends on the codec chip.
Xavier, i'm assuming you have a ALC260 codec chip because that chip supports "model=hp".

my codec chip is STAC9228.
these are the only supported model, none of which work.

STAC9227/9228/9229/927x
ref Reference board
3stack D965 3stack
5stack D965 5stack + SPDIF
dell-3stack Dell Dimension E520

Of course, I didn't want you to try hp, just the possible models for your chipset. (hp supports several chipsets btw, mine is AD1981)
But if you already did, fine.
I guess you should indeed try to build the alsa 1.0.16 driver then.
Or try 2.6.25 kernel which has 1.0.16rc2, as I said. 2.6.25 is in testing for a while already, but I am not sure what its status is and when it will be moved.

Yeah, I am using 2.6.25 right now to no avail:

Dunno, have been giving up on this - it used to work before on 2.6.23. Ever since .24 this has been been defunct. Sad.
BTW, I have tried all kinds of drivers for this chipset. All not working.

Here in my Vostro 1400 i have the same problem. Mic never works, with any version of alsa of kernel. What i have now:

Ok,
I have found out that this might be a xfce-mixer bug for me.
If any of you is using XFCE, you might want to try a different mixer. For me, everything works fine now with gnome.
If it doesn't work for others, I am sorry for my added noise.
Cheers,
Martin

Oh, if anyone is interested, I have a PKGBUILD for alsa-drivers 1.0.16 mercurial that uses /lib/modules/$(uname -r)/updates.
Send me an email...

I alsa tryed with alsa-driver .16. Not work too.

I found a "fix" for this bug :
- install gnome-alsamixer
- set the internal volume at 0
- check the Rec checkbox
- modify mic-boost, digital and capture volume

It seems to work with an Intel IHC7 rev 01, haven't tested with a rev 02, but may work too.

For any reason of unknown, mic works now. I dont now what happens, but works after 2.6.25 kernel.

Should this be closed then?

Yes, sure.
