HDMI Audio out fails on Geforce 8200 (MCP78)

[Kyle Echols]

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.

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)

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1264636/+editstatus and add the package name in the text box next to the word Package.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1264636

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Attaching output of alsa-info.sh while running the 3.11.10 kernel (alsa-info.txt.kernel_3.11.10_20131228), I can roll back to the release kernel and re-run the script if needed.

[penalvch (penalvch)]

Kyle Echols, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

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.

[Kyle Echols (kyleechols)]

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.

Kyle Echols, thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the original issue "HDMI Audio out fails" has been fixed in the latest development version of Ubuntu - Trusty Tahr as per as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1264636/comments/7 .

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.

Regarding the keyboard/mouse problem, so your hardware and issue may be tracked downstream as well, please feel free to file a new report with Ubuntu by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:
ubuntu-bug linux
