[ltp] T61: No sound from internal speakers

[Marcus Better]

Hi,

I get no sound from the internal speakers on my T61, but the headphone jack
works. I'm running kernel 2.6.25 (x86_64), ALSA userspace 1.0.16.

My R60 never had this problem. (Yes, I've pressed the "volume up" button to
unmute, and unmuted the master channel in alsamixer.)

Cheers,

Marcus
