As far as I followed upstream, work is being done on this matter in the Linux kernel, not really in Ubuntu. (Since it is not a packaging bug, but rather a development task)
Current focus seems to be to make sure audio works in HDA mode. I2S mode is apparently improved in kernel versions 4.0 and 4.1, but it is still rather new and not as mature as the HDA code. There is definitely effort in progress on making this work out of the box with the Linux kernel. For the moment I can just advise to update to the most recent firmware version (A03 at the time of this writing). This gives you working audio in HDA mode. I2S mode audio will be enabled when the code for it is ready in terms of code quality and feature completeness. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1413446 Title: Audio broken on 2015 XPS 13 (9343) in I2S mode in Ubuntu 14.10/15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1413446/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
