HI,I have about the same type of problem,went into device manager and it said
it could tell if this port was working it came up with CODE34,what ever is this.
IT has question mark over the the port which i assume means it is not working
have looked all over a reason,but have come up empty so far,when i go into MASTER VOLUME
there 4 mute squares faded out one of them is the rear speaker which is where i have my speakers hooked up at
