1) When you say without any patch means without any change through hdajackretask ?
2) With connecting the pins through hdajackretask ? Anyway, the first question that would be good to solve is to know how many loudspeakers are effectively in that box because I don't realy understand what front and surround speakers are in this situation. As far as I know they are 3 : R/L front speakers and the subwoofer. So where is that "surround" coming from in alsa ? I will try to find a schemes of that setup to know exactly how is that box configured. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1302090 Title: Dell Alienware 14, Speaker sound output is mono until a headphone jack is plugged To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1302090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
