I can confirm the same behavior on a Lenovo ThinkPad X121e, which uses the same codec.

The left speaker works, the right one doesn't. Or maybe it does, but it's almost silent. If you pan the mixer to the right, sound is audible, but very, very quiet.

Headphones work like a charm.

Status changed to 'Confirmed' because the bug affects multiple users.

same issue for me... I have a Lenovo G570
