I was able to fix this by adding "options snd-hda-intel model=dell-m6 enable_msi=1" to the end of "/etc/modprobe.d/alsa-base.conf", as per http://www.linlap.com/wiki/dell+studio+xps+16. Just "options snd-hda- intel model = dell-m6" doesn't work.
There's still no sound from speakers, but since I have the same problem in Windows, I suspect this is a hardware problem. -- No sound on Dell Studio XPS 16 https://bugs.launchpad.net/bugs/610932 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
