Getting closer! Mainline kernel 4.2.0-rc5 shows the rt286 audio just like 4.1.3 did, and the touchscreen is back! However, there's still no sound. :-( It behaves like it's playing, tho. I've checked and pavucontrol shows everything is there and the sound is showing on the audiometer. Nothing appears to be muted. I've muted and unmuted things a few times but no go.
I also tried with and without acpi_osi="Windows 2013". No effect. I understand, tho, that from 4.2.0 onwards, this flag is no longer required? ** Tags added: kernel-bug-exists-upstream-4.2-rc5 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1477859 Title: Onboard Audio not working on Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1477859/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
