I spoke too soon. Sound was working the first time I switched from 4.9 to 4.4, though volume couldn't be changed in the UI.
However, after I rebooted again (4.4 -> 4.4) I never got sound to work again. I'm now returning the laptop (for this and other reasons - e.g. battery life sucks) so I can't be any further assistance on this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1649727 Title: No sound card detected with device: Intel Corporation Device 9d71 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649727/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
