Running on Lucid and have HDA NVidia ALC662 chipset on mobo with 3 jacks (ECS GeForce 7050M-M also have a nVidia GeForce210 card added on it.

On Jaunty this worked fine, but when i installed lucid for some reason i can not get surround sound out on analog, i tried moving the cable to different jacks and each one played a different speaker - the sound all came from the front speakers - but from alsamixer they were outputting on different speakers - surround, LFE etc

How can i check / fix this jack sensing issue?
