As I have mentioned, this is an MSI GX 720 laptop. By default it is equipped with 4.1 internal sound speakers. There are four jacks at the right side. I think, by reading the manual, that is the default setup and the 4 jacks can be used for 5.1 and 7.1 sound as well. The windows driver automatically detects if something is plugged to the jacks and based on the order it start to use it. The manual gives the following order (from left to right order): 1 - green jack plug - FR/FL 2 - empty - N/A 3 - black jack plug - RR/RL 4 - yellow jack plug - SUB/CEN It is OK, that did not use 5.1 by default, but why the 4.1 is not detected? Big question. I might need to update the BIOS to get it. (I would hate to do that.) By the way, it was correctly detected before 9.10. Since that, I always had a problem.
