I checked the DSDT tables and couldn't see anything blatantl= y wrong. If there was a problem with the compress DAI it would show on other platfor= ms as well. It could also be a configuration issue with bad controls, I put my UCM conf= iguration on github plbosssart/UCM/, you may want to look into this as well. -Pierre
