question about alsa driver

arkanoid · 2006-10-05 19:04:14

hi,

hope i post in the right place ..

i recently bought an acer laptop (aspire 1640z), which was fine, several hours later i got rid of the installed xp, having arch working perfectly on it. 8)

appart from the sound, the ACL883 chipset is bugged in alsa 1.0.12. it has been fixed in the 1.0.13 version, but the current arch kernel's still compiled with the older version.

my question is, can i make a PKGBUILD for the alsa-driver without recompiling the kernel ?
if not how can i do to compile the kernel with new alsa driver support ?

yes, i installed this package, then run

cat /proc/asound/version

but still the driver (it's a separate source from the lib) is in 1.0.12

so i deduced that alsa-driver is compiled within the kernel, am i wrong ?

you must run

alsaconf

after installing

alsa-libs

and

alsa-utils

did it

still the driver in 1.0.12 version

Somewhere in the back of my head I remember that you actually had to change a configuration setting to have alsa use the latest driver. This was some time ago though and I can't really remember. Anyway, you can always try to remove alsa entierly before reinstalling it. (pacman -Rs alsa-utils).

I checked the cat /proc/asound/version and you are correct it reports 1.0.12 rc1 .
However, if you check /usr/include/alsa/version.h it clearly shows 1.0.13 as version.

maybe there's someone who can tell why those numbers are different, but i think we should try to solve your problem with the sound.

Have you followed the instructions in the Alsa entry in Wiki ?

Do you get any error messages ?

arkanoid · 2006-10-05 20:24:20

i don't get any error message. in fact card is recognized by alsa conf and audio softwares actually run, but no sound

there was a bugtrack about my chipset in alsa cvs

https://bugtrack.alsa-project.org/alsa- … ttachments

so it seems to be fixed in 1.0.13 of the driver.

i checked http://www.alsa-project.org and they seems to have separate source for alsa-driver , alsa-utils, alsa-lib .

that's why i ask myself if alsa-driver is compiled within the kernel, after a read on a gentoo wiki that told that it can be either compiled within or outside the kernel. so i don't know the way it works in arch ?

Ok, that makes things a lot clearer.
I've found something on the alsa website Updating ALSA Kernel drivers that says you can find the alsa kernel driver version in linux/include/sound/version.h

For arch that would be in this folder /usr/src/linux-2.6.18-ARCH/include/sound , and the version.h gives 1.0.12rc1 as alsa kernel driver version.
It definitely looks as though we have the alsa kernel driver compiled in the kernel and it needs to be updated.

Please file a bug request on Flyspray.
