I add the following line to the end of my modprobe.conf

<code>
options snd-hda-intel model="olpc-xo-1_5"
</code>

That worked for my Edge 13 amd (Arch Linux :)).

Thanks a lot for that tip, it worked perfectly for me on Ubuntu 10.04 on
my Edge Intel 13".

But the file on Ubuntu 10.04 is:

/etc/modprobe.conf/alsa-base.conf

chezka & Andrew, make sure you file new bugs against alsa-driver so
that your PCI SSID is included. We'll need to fix the driver.

chezka ~ $ lspci

...

chezka ~ $ cat /proc/asound/card0/codec#0 > proc.txt

p.s.: where i can get PCI SSID? :)

THANK YOU !!! I can also confirm chezka's solution works on my Intel Edge 13, running Ubuntu 10.04.

I have an identical problem with Lucid on my Toshiba Satellite Pro T130-15F Laptop.
Codec: Conexant CX20582 (Pebble)
Sound comes from speakers when headphones plugged in.
I have taken today's daily release 2.6.32-21-generic and run it in "live CD mode".
Everything else works fine btw.
Uploading:
dmesg, alsa-info lspci.
Many thanks.

Yes.

Status in “alsa-driver” package in Ubuntu: Incomplete

Bug description:
I installed Lucid beta on a new laptop, a Thinkpad Edge. It has one of those
duple...

Update - I have installed Lucid on my Toshiba Satellite Pro. And can get sound out of the headphone socket if I apply the above fix to alsa-base.conf:
options snd-hda-intel model="olpc-xo-1_5"

... but will file a bug report with PCI SSID details

Added bug report Bug #573493 for my SSID

This worked for me too on an AMD based Thinkpad Edge running ubuntu 10.04 x64. I didn't have a modprobe.conf and alsa-base.conf was in /etc/modprobe.d/alsa-base.conf

The trick adding the option for OLPC XO 1.5 worked for me as well on my Thinkpad Edge 13 with AMD after restarting Ubuntu 10.04. Thx. (o:

Hopefully noone has to do this manually again in the next alsa release.

The above fix by adding extra line in alsa-base.conf:
        options snd-hda-intel model="olpc-xo-1_5"
 also solved my problem (Lucid, Thinkpad X100e, pebble 20582).

Another issue arose after the fix though.
My internal mic simply didn't work then, sounds like a side effect, and I've no idea how to fix that. I tried to install the latest ALSA drivers (1.23 release), just in vain.
When I test the mic by "arecord -vv -fdat my.wav", that's indeed a file generated, but when playing back the generated file, nothing went out. Using audacity to open the my.wav showed no waves.

Before upgrading to Lucid, the mic used to work well.Hanging around the web for a while without any suggestion found yet.Hopes any one can figure out the root cause and suggest some workarounds.

Thanks!

I noticed the problem has returned. I double checked and the options snd-hda-intel model="olpc-xo-1_5" line is still in my /etc/modprobe.d/alsa-base.conf file but when I un-muted my sound it came out the speakers only again whether or not the headphones were plugged in. Nothing comes out of headphones. I will reboot and see if it works or not...

Hi,
I have AMD based Thinkpad x100e.
  options snd-hda-intel model="olpc-xo-1_5" in alsa-base.conf works for headphones. Bu microphones doesn't work (internal and external jack). i don't capture sound any way.

What should i send?
Thanks.

@Hakan
            Proper x100e support is already in upstream alsa project.
http://git.alsa-project.org/?p=alsa-kmirror.git;a=commit;h=86c65362321c5d5983645917760c150d289d163b

            This code is not in the lucid kernel. It should make alsa backports package soon (though I'm not sure on a data for it to land).

The workaround above fixed my headphone issue, but the problem now is that I cannot adjust headphone volume using general sound properties. It seems to be set at maximum level.

Mic does not work here either. Please let me know in case of any needed information.

the fix didn't work for me on a Toshiba T115D-S1125 running lucid.

Maybe, you must see "alsamixer" in terminal, then F4: the Capture option, and pulse the M key to active MIC (MM = Off, OO = On)

Thinkpad X100e - Ubuntu 10.4 - ATI Technologies Inc SBx00 Azalia (Intel HDA) - Chip : Conexant CX20582 (Pebble)

I don't have any sound in my headphones.They don't exist, I can't "see" them with PulseAudio controller.

Adding the options snd-hda-intel model="olpc-xo-1_5" line to the end of my modprobe.conf solved the problem for a short time, but it's no longer the case.

@iGor.m

at the moment the best way to go about the issue with thinkpad X100e is to install the conexant driver from www.linuxant.com. Use the driver the suites your OS ...
Here is the link http://www.linuxant.com/alsa-driver/

@juliobahar

thank you for the informations!

Adding options snd-hda-intel model="olpc-xo-1_5" to alsa-base.conf ALSO solves the problem for Ubuntu 10.10 Maverick Meerkat

oops, i take that back about the solution for 10.10RC on thinkpad edge.
the audio output seems to stick to the first option: if i turn on the computer with a jack plugged in, then only the external audio will work (irrespective if i unplug it or not). if i turn it on without anything plugged in, only the internal speakers work.

(muting works as it should)

Can someone please squash this bug or at least find a temporary workaround. My headphone jack won't work. I have a Toshiba Satellite T115D-S1125. Just like @sergio above...

Still doesn't work on Toshiba Satellite T115D-S1125 with ubuntu 10.10 / 2.6.35-23 with or without the above fix Headphones are ok, but no internal mic.

chezka's fix worked for me on an AMD Thinkpad Edge 11. But I also had to install the linux alsa driver modueles from this link,
https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules . After that headphones and speakers were fine, mic not tested yet.

Have thinkpad edge 11". Updated my ALSA drivers and added options snd-hda-intel model="olpc-xo-1_5" to alsa-base.conf. Headphones and speaker work. Internal mic does not work. Cant test external mic because I don't have the proper adapter
