Comment 11 for bug 683487

Yes, I've finally had a chance to check the model=thinkpad option and can confirm it works (obvious, really, given this is a thinkpad model :-).

Testing w/ sound recorder: without external phones plugged in, inbuilt audio output and input works. With a combo headphone/mic phones plugged in, inbuilt mic+speakers are muted and the external phones/mic work.

Thanks Daniel, William, Benjamin, Peter.

BTW, the "mic mute" / F4 key does not function but I expect that's not an audio driver issue (ditto camera mute for that matter).
