[Bug 611810] [NEW] [PATCH] NVIDIA GPU audio-over-HDMI: Patch required to support recent GPUs

[Stephen Warren]

Public bug reported:

The kernel ALSA driver needs a patch applied to make audio-over-HDMI
operate correctly on most supported GPUs.

The exact patch is available at http://git.alsa-project.org/?p=alsa-
kernel.git;a=commitdiff;h=4289bc9c818ece46f8034616b232caaef4622984

It'd be great if this patch could be included in the standard Ubuntu
kernel(s) for any/all recent or supported distro versions.

Note 1: I believe only the nvidia driver (not nv nor nouveau) support
setting up audio-over-HDMI.

Note 2: Very recent GPUs (Fermi class) are not yet supported by the
driver. A second patch will be forthcoming for this at some point in
time, but we have to validate operation under Linux before releasing
this.
