[Justin Sunseri (jmsunseri)]

after the update of the kernel today to 2.6.15-21.32 sound works properly without having to modprobe any extra modules. I would say this bug has been fixed.

[Alex (xp-newbie)]

Sorry to bring the bad news, but as of today (June 14, 2006), with kernel 2.6.15-23-386 installed on my Lenovo 3000 N100 (type 0768, model 36U), sound works only if I added to /etc/modprobe.d/options the following line:

  options snd-hda-intel model=laptop-eapd

[Daniel T Chen (crimsun)]

Using "laptop-eapd" is the known workaround (and the original "fix" applied in earlier Ubuntu kernels) while upstream addresses the issue.

[Tim Haughton (timhaughton)]

The "options snd-hda-intel model=laptop-eapd" workaround does not work for me on this laptop, is there anything else I can try?

Module loads OK, just no sound. Is there any way it isn't picking up the options?

[Daniel T Chen (crimsun)]

@Tim: Please reload the module without any additional parameters.

[Tim Haughton (timhaughton)]

Done, but still no sound.

[Tim Haughton (timhaughton)]

Please ignore previous. Kernel update fixed it - my mistake. Had specific 686SMP kernel selected rather than meta package.

[Daniel T Chen (crimsun)]

These models should have audible sound by default; see the reinstatement commit id f939a127702d733ca9e87cbed300cf33b875c3b3, http://www.kernel.org/git/?p=linux/kernel/git/bcollins/ubuntu-dapper.git;a=commitdiff;h=f939a127702d733ca9e87cbed300cf33b875c3b3;hp=9eb3ccc545428daf1bc741e6f08e5cd597e47dfc

[Denes Kiss (kiss-denes)]

No sound on Lenovo 3000 C200 either.
It has almost the same lspci output, and I have already tried options and new alsa compilation, but no result.

The interesting is, that the XP recognizes Realtek sound card, and uses Realtek driver.

[Daniel T Chen (crimsun)]

Denes, is the modem enabled or disabled in your bios?

Daniel,
The modem was enabled in the bios. I set it disabled, but no change.
I use Ubuntu 6.10, kernel 2.6.17. I compiled the new alsa 1.0.14rc2.
(The hardware should be good, because XP works.)
I can unload the driver by /etc/init.d/alsasound stop, and load it with
modprobe -v snd-hda-intel.
I do not find any fault. Alsamixer on the max. On board volume on.
With regards: Denes

Denes, please open a support ticket[0] instead of following up here. Thanks.
