After more than a few attempts, I was able to get keyboard and mouse working on the 12/28 alpha build of 14.04 (kernel version 3.12.0-7-generic ), with this release, hdmi audio "just works" after un- muting the correct output in alsamixer. Since this is not an installed release, i couldn't install the nvidia drivers so can't confirm stability with them. My USB keyboard and mouse stopped responding entirely after be left alone for a few (<10 ) minutes.
So audio is fixed, but there is still an intermittent USB issue with this kernel release. I will be re-installing 12.04.3 tonight so that I can make sure I have not missed anything in the steps to get sound working and to try to get something resembling stability back to this machine. Once the install is complete, I'll update to the latest kernel, retest, and report back. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1264636 Title: HDMI Audio out fails on Geforce 8200 (MCP78) Status in “linux” package in Ubuntu: Incomplete Bug description: I have an XFX Geforce 8200 (MCP78) motherboard. 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.
