Re: Lenovo 3000 V200 - no sound from internal speakers but OK on headphone jack

You mostly tried the wrong model options.

According to the diagnostic script your Lenovo has a CX20549. I believe that used to be known as a Conexant 5045 which means according to the HD-Audio-Models.txt file the options to try are laptop-hpsense, laptop-micsense, laptop-hpmicsense, benq, laptop-hp530.

This is from that referenced file:

Conexant 5045
=============
  laptop-hpsense    Laptop with HP sense (old model laptop)
  laptop-micsense   Laptop with Mic sense (old model fujitsu)
  laptop-hpmicsense Laptop with HP and Mic senses
  benq        Benq R55E
  laptop-hp530    HP 530 laptop
  test        for testing/debugging purpose, almost all controls
        can be adjusted.  Appearing only when compiled with
        $CONFIG_SND_DEBUG=y

Your alsa sound driver version, at version 1.0.21 is old.

I'm running Ubuntu 10.04, and sound plays fine to the headphone jack only - no sound from the internal speakers on this laptop.

I've tried following the normal diagnostic path, and tried model=lenovo, model=laptop, and model=test but none help.

Here is the output from alsa-info:



Any help would be greatly appreciated.
