Yeah, I know.  But the speaker-muting should work even without
hp_detect=1 hints.  The IRQ thingy was only about the auto-muting.

Also, with the latest version, the device might work even without the 
extra model option (as the auto-parser got improved).  I'd like to
avoid unneeded quirk lines as much as possible, so that's why I asked
to check the latest one.

Thanks!
