Bug 151761 – alsa-driver patch for Conexant sound cards

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Scott Van Der Wall 2006-10-17 16:39:56 UTC]

There is a patch for Conexant devices that is eventually going to be incorporated into the alsa-driver, however at the moment is not.  I believe it works with 1.0.12 and greater.  It would be nice if it was incorporated into the ebuild for the alsa-driver.  I'll post the patch up here.

patch for low sound output

This patch is for conexant devices (mainly hp laptops) that are experiencing low sound output.

[Comment 2 Jakub Moc (RETIRED) 2006-10-17 22:52:24 UTC]

Did you send this upstream?

[Comment 3 Scott Van Der Wall 2006-10-18 00:42:51 UTC]

This was a patch created by someone else and has been submitted to the people at alsa.  However they are taking their sweet time implementing it.  I believe it was submitted at the end of august.

[Comment 4 Scott Van Der Wall 2006-10-22 23:49:15 UTC]

So there are two almost offical patches now from alsa.  They are in the testing phase, but they work.  I'm using them now and they work well.  I'll post them up here.  It seems that it will be included in 1.0.14-rc1, so whether or not they are included in portage's patches for 1.0.13 or not is up to you guys.

[Comment 7 Scott Van Der Wall 2006-10-22 23:52:27 UTC]

Here's the directions from the discussion about these patches from the creator:

Ok, I have a couple of test patches to try. They are separated for integration into the HG repository, so to add them to alsa-driver-1.0.13.tar.bz2 (downloaded from the main page), follow these steps:

tar -jxvf alsa-driver-1.0.13.tar.bz2
cd alsa-driver
patch -p1 < conexant-driver-test1.patch
cd alsa-kernel
patch -p1 < conexant-kernel-test1.patch
cd ..
./configure --with-cards=hda-intel --with-debug=detect ; make ; make install


After compiling and loading the drivers, send me the output from dmesg. Run dmesg -c before loading to get a clean, short output. Also, please post the output from "cat /proc/asound/card0/codec*".

Let me know if this works or not. If it compiles and works, even marginally better, I'll get it into the tree and we can fix it from there.

I've got HP Compaq V3000Z with this Connexant HDA. I've got problems with alsa-driver-1.0.13. When i try to unload and load again this module freezes whole system (look at #153771 bug), but at init (alsasound) loads without errors. When trying to play some music it fall in infinite loop (first second of mp3) and player (amarok) hangs up.

I tried alsa from gentoo-sources 2.6.18-r2 kernel, and there sound works fine (but only on speakers - no headphone out there).

Everything ok, after adding disable_msi=1 parameter to modprobe. AFAIK model recognition is good.

[Comment 10 Diego Elio Pettenò (RETIRED) 2007-02-17 02:31:29 UTC]

Leaving this for upstream, I try not to patch the drivers.
