The only thing really missing from this install is this issue with the sound. I've searched all over the forums and i found one thing where you get the model and codecs and write them to a file, however, I can't seem to find what my "model" is because none of the postings have anything about Lenovo laptops. Here is the command they all asked for: Code:

cat /proc/asound/card0/codec#* | grep Codec
Codec: Realtek ALC269
Codec: Intel G45 DEVIBX

With that info, how do I get the model, and how do I get my speakers to stop playing when headphones are plugged in. Also, if i manually change the output device to headphones itll play just headphones in the sys prefs... so it CAN work, but it doesn't.

I have a Lenovo ThinkPad L512 as well.

Thanks so much to whoever can answer this...

The Ubuntu forums are nearly useless... ive never gotten a correct answer back on that site.

Also, i've filed a bug report and i know it's the ALSA plugin, i don't know how to fix it though.

  • What are your alsamixers like? Run "alsamixer -c0" (no quotes) in a terminal. – NightwishFan Sep 25 '10 at 00:03

  • All you can really do is wait for the bug to be fixed. I'm assuming you either included alsa-info.sh output or used ubuntu-bug linux or ubuntu-bug -s audio to include debugging info – maco Sep 28 '10 at 00:44
  • The mixer channel to do so is usually called front. It might be pulse restricting it. EDIT: I see you have no front. You can use the M key to mute a channel. Try playing with the mixers. – NightwishFan Sep 28 '10 at 00:52

This is a workaround:

Go to "sound preferences" and select the "Output" tab. There select "Analog Output" in the connector option.

Where is your LP bug? I don't see it listed anywhere.

I wonder if we're setting a quirk incorrectly in /sbin/alsa-utils. That gets fired off on hotplug events.

As a quick test, you could comment out this line:

    exec /sbin/alsa-utils start $N

which can be found in /lib/udev/alsa-utils. Commenting it out will prevent the hotplug script from firing. Reboot after you comment it out, and see if that improves behavior any.
