Hello Raymond,
thanks for your answer.
I checked the Dell thread and the Realtek datasheet. I see it's possible to connect to external 5.1 (or 2.1) sound system.
However I want to make it work with the *internal *2 speakers + *internal * subwoofer.
I've read tons of links and similar threas, it seems it is not possible under linux :-(
Regards,
Tomas Black

Dear friends,
I have a Dell L702X laptop which comes with a 2.1 sound configuration - 2 speakers + subwoofer from JBL. Sound is suberb in Windows, but I can't get the subwoofer to work in Linux!

Take a look at datasheet,
ALC655 is a 5.1 codec and a MONO out
either the subwoofer is at the MONO node 0x17 or the right or left channels of the other unconnected stereo nodes
try hdajackretask to change the pin default of node 0x17 to [Fixed] Speaker at Int

seem support 5.1 using two headphone jacks and mic jack
