I've tested with the ubuntu 14.04 Alpha (12/28 build) and ubuntu 13.10 and was unable to use my keyboard or mouse, this appears to be due to an upstream kernel bug, https://bugzilla.kernel.org/show_bug.cgi?id=60507. This problem also exists for 12.04.3 with the 3.11 kernel, however, it is intermittent and a reboot will usually clear it up. I will test 12.04 with the latest kernel either later today or in the next couple of days and update further.

While HDMI video out works fine, HDMI audio doesn't work with the 3.8 kernel (3.8.0-29 or 3.8.0-34), I've tried with both the nouveau and nvidia binary drivers. The analog outputs work with either driver. WORKAROUND: After upgrading to kernel 3.11.10-031110-generic, from the kernel mainline PPA, and using the nouveau drivers I'm able to get audio out over HDMI, using the following options in /etc/modprobe.d/alsa-base.conf: options snd-hda-intel single_cmd=1 probe_mask=-1,0x8 unmute iec958 While using this configuration, I have audio and it's mostly stable, however, I'm unable to take advantage of 3d acceleration and HD video playback is choppy. If I then use the any of the nvidia drivers (304, 319, 331, or current) I get frequent crashes, including system lockups. I have confirmed with VLC, mplayer2, and speaker-test that no audio comes out through HDMI until the 3.11 kernel, nouveau drivers, and the modprobe options mentioned are all in place. I'm attaching 20131228_logs.zip containing the output of: aplay -lL (aplay_out) lspci -k (lspci_out) and the following additional files: dmesg dmesg.0 lsb-release uname -a returns: Linux DVR 3.11.10-031110-generic #201311291453 SMP Fri Nov 29 19:54:20 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux This is the kernel that has working audio but is unstable with the nvidia binary in use (and choppy hd playback with nouveau) --- ApportVersion: 2.0.1-0ubuntu17.6 Architecture: amd64 DistroRelease: Ubuntu 12.04 InstallationMedia: Mythbuntu 12.04.3 "Precise Pangolin" - Release amd64 (20130820) MarkForUpload: True Package: linux (not installed) ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash Tags: precise Uname: Linux 3.11.10-031110-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm audio cdrom dip lpadmin mythtv plugdev sambashare sudo video To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1264636/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
