Description Casual J. Programmer 2007-01-28 18:27:20 UTC

+++ This bug was initially created as a copy of Bug #138434 +++

The soundcard is detected and installed correctly during the installation, playback and system audio is fine with gnome. However, microphone gives no input at all with any application (audacity, krecord, skype, etc.)

Alsamixer: all channels to maximum volume

Output of hwinfo --sound:

Copy, compile and install of alsa-driver-hg20070127.tar.bz2 from ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver/ does not better anything.
The Alsa Mixer Gui shows additional information:
Card: HDA Intel
Chip: Conexant CXT5045

Comment 4 Takashi Iwai 2007-01-29 14:51:46 UTC

Unfortunately, this hardware is _not_ supported by 2.6.18 kernel on openSUSE 10.2 kernel.  It's still not supported on 2.6.20, but will be better on 2.6.21 kernel.  Since we want to keep the kernel as close as vanilla, this will be unlikely fixed in openSUSE 10.2 updates.

You can try alsa-driver-1.0.14rc2 release from www.alsa-project.org, which has most of recent fixes.

Comment 5 Casual J. Programmer 2007-01-31 09:07:20 UTC

Can you devise a proper procedure for replacing the driver ?

Is it enough to just "make install" the driver only, or would I rpm -e alsa --nodeps to remove any leftovers ?

I actually completely removed all alsa components with rpm -e, and compiled / installed everything as per http://alsa-project.org/alsa-doc/doc-php/template.php?company=Intel&card=ICH+southbridge+HD-audio+and+modem.&chip=ICH6%2C+ICH6M%2C+ICH7%2C+ESB2&module=hda-intel
It seems to work ( alas not the line in yet ), but the alsa service is no longer starting automatcally, the devices need to be created and given proper rights by hand.

There must be some easier way :-(

btw. the Linuxant modem drivers fromhttp://www.linuxant.com/drivers/hsf/full/downloads.php work perfectly with alsa.

Comment 6 Casual J. Programmer 2007-01-31 11:32:05 UTC

After receiving information from https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2477, indicating that the exact same hardware is working with vanilla kernel 2.6.19 and vanilla alsa drivers, I installed kernel-default-2.6.20_rc6-2.i586.rpm from factory.

Apart from the fact, that "Line In" and "Ext Mic" are gone now ???, I can record from source "Capture", although volume is low and there is some hum in the background. This seems to indicate rather a kernel issue than a driver issue.

Comment 7 Takashi Iwai 2007-02-16 17:57:59 UTC

Merged to 10.2 report.
