[SOLVED] Recent kernel upgrade breaks snd-hda-intel digital audio (0810)

[chrisbirkinshaw]

UPDATE: I changed the title of this thread as it now affects my other non-ION system, also with a hda intel chip. This is related to the kernel upgrade - see here:

http://bbs.archlinux.org/viewtopic.php?id=69658

and here for some assistance:

http://wiki.sabayonlinux.org/index.php?title=HOWTO:_Resolve_Problems_with_HDA-Intel_Sound_Cards

SOLUTION: The only solution I found was to compile alsa .22 drivers from source:

1. wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.22.1.tar.bz2
2. tar xjf alsa-driver-1.0.22.1.tar.bz2
3. cd alsa-driver-1.0.22.1
4. ./configure
5. make && make install

Be sure to reboot afterwards


------------------------------------------








After the recent alsa upgrade my nvidia ION based system no longer shows any digital devices. I have tried adding options in the /etc/modules.d/alsa-base.conf files as follows:

options snd-hda-intel model=3stack-6ch-dig enable=1 index=0

I also tried 6-stack-dig, and a bunch of other combos based on blog posts I found on the net. Any ideas?

NB it was working up until yesterday.

Thanks. Tried it but sadly did not work...

The following packages have unmet dependencies.
  libavcodec-dev: Depends: libavcodec51 (= 3:0.svn20080206-12ubuntu3.1) but it is not going to be installed
  libavformat-dev: Depends: libavformat52 (= 3:0.svn20080206-12ubuntu3.1) but it is not going to be installed


Seems to be a bit of a mess. Any clue why this is happening? Sound worked fine until I ran apt-get dist-upgrade yesterday...

hmm, I don't know...I have a asrock ion 330 and I also did apt-get dist-upgrade yesterday, but mine is still working.
Why don't you pop by the irc, I guess the guys there can help

[chrisbirkinshaw]

Hmmm. Just wondered - what do you have in your alsa-base.conf and what does dpkg show for the version of alsa-base? Also, what about lspci?

Thanks,

Chris

here is my alsa-base.conf

# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2

install sound-slot-4 /sbin/modprobe snd-card-4

install sound-slot-7 /sbin/modprobe snd-card-7
# Cause optional modules to be loaded above generic modules
install snd /sbin/modprobe --ignore-install snd && { /sbin/modprobe --quiet snd-ioctl32 ; /sbin/modprobe --quiet snd-seq ; }
install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi && { /sbin/modprobe --quiet snd-seq-midi ; : ; }

# Prevent abnormal drivers from grabbing index 0

options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2

this is what lspci says:

Description: ALSA driver configuration files
 This package contains various configuration files for
 the ALSA drivers.
 .
 For ALSA to work on a system with a given sound card,
 there must be an ALSA driver for that card in the kernel.
 Linux 2.6 as shipped in linux-image packages contains
 ALSA drivers for all supported sound cards in the form
 of loadable modules. A custom alsa-modules package can
 be built from the sources in the alsa-source package
 using the m-a utility (included in the module-assistant
 package). Please read the README.Debian file for more
 information about loading and building modules.
 .
 ALSA is the Advanced Linux Sound Architecture.

In the end I upgraded to alsa .21. It seems that somewhere between .18 and .19 something odd happened breaking support for a some chipsets. With the .21 driver the cards on my ION and also my other motherboard are properly recognised now.
