If you have "Headphone Jack Sense" mixer control, try to turn it off.

Check that the driver snd_i8x0m (for the modem) is not being loaded.
Although i don't think this is your problem because is broken too in
2.6.10...

Glad to hear that. What machine do you have?

Hi Takashi,
The same applies for IBM T40/T41/R50p I have tested so far.
I had to disable "Headphone Jack Sense" and "Line Jack Sense" too.
So, what's the deal with these ?
What are they supposed to do ?
Should we report this as bug on alsa lists ?
Thanks,
Paul

These switches enable the automatic mute when the corresponding jack
is plugged. On machines like HP and Fujitsu need this switch on to
avoid the sound from the internal speaker when you connect to HP
jack. AFAIK, Thinkpads conflict with them.

This was already fixed on ALSA tree.
