(in reponse t o#76) Raymond, the subwoofer signal is not a different output-bus on this laptop, it's something built into the sound card. There's no need to 'jack detect'. I have this laptop and applied the fix mentioned above. Still, my mixer only shows a stereo output (and the subwoofer works).
The hardware is connected via a proietary jack, not a 1/8" or RCA jack. What I believe the problem is, is that ALSA does not assign the right "model" according to the firmware ID on this laptop, or some other mumbo-jumbo that I am not familiar with. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871808 Title: Asus N55SF/N75SF - External subwoofer not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/871808/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
