Me too. :-) Once Timo has a finished build (and I've provided him with a version that actually compiles, *ahem*), could Anthony help assign people to help us test it? It would be very nice if we could have this tested on more than one of (Skylake / Broadwell / Haswell). @Anthony, if you look at the duplicates for bug 1490895 (e g, 1383997) I think you'll quickly understand what all of this is about. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1490895 Title: Skylake/Broadwell/Haswell: No HDMI audio jack detection in D3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
