 Posted: Fri Dec 21, 2007 9:46 am Post subject: No more LFE with intel-hda and kernels 2.6.23-xxx [SOLVED] |
 |
|
Hi.
I didn't notice earlier but LFE slider has gone (once more) in ALSA settings. I've switched a couple of weeks ago to Gentoo Sources 2.6.23. LFE is also absent in Kamikaze sources 2.6.23-5. I'm sure I still had it with previous Gentoo Sources.
What's going on again with Intel HDA? Or is it my settings?

there is something wrong in your config.
Read | Code: | | /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt |
and try to add correct option to /etc/modules.d/alsa | Code: | | options snd-hda-intel model=6stack-dig |
That works for me (not as I want, but I'm happy with it) |

The options have always been the same
| /etc/modules.d/snd-hda-intel: | | options position_fix=1 model=ref |
Now I have edited the file
| /etc/modules.d/snd-hda-intel: | | options snd-hda-intel position_fix=1 model=ref |
and also tried
| /etc/modules.d/snd-hda-intel: | | options snd-hda-intel position_fix=1 model=dell-m27 |
but it doesn't change anything. Still no LFE slider in alsamixer... I've even run update-modules -f and rebooted, no change... 
My chipset is a STAC9200 (Dell Inspiron 9400). How can I make sure the options were passed to the module and the subwoofer was detected?
EDIT: Of course, now that I've rebooted with a 2.6.22-gentoo-r8 kernel, the problem still persists...

It looks like a bug in Alsa kernel module, which has some incorrect/missing pins setup for STAC9200 on some Dell models... Hmmm...

I have fixed the bug after reading this thread (it's Ubuntu but applies here too). Here's the full patch - note that you'll have to change the patch header as follows to patch your kernel sources directly:

To patch your kernel, run the following commands:
| Code: | cd /usr/src/linux
patch -p1 < /path/to/dell-lfe-alsa-1.0.14.patch |
Then I've had to change /etc/modules.d/snd-hda-intel parameter model=ref into model=dell-m27. Finally I've also had to upgrade alsa-libs, alsa-utils and alsa-headers all three to version 1.0.15 (currently ~masked) to get rid of the wierd debug message "XXX write TLV" after /etc/init.d/alsasound restores sound mixer levels.
