FWIW this is the specific chipset: Realtek ALC3253 I grep'd through the source tree and didn't see any references to this chipset, I suspect this is a new driver/codec that needs to be created or imported? It looks like linux only added support with the 4.11 kernel... Cheers, -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
