Thanks Jassi.... I'm going to set this to wishlist on our side then.  I
don't know if the hardware can do 5.1 but this starts to become an R&D
effort rather than a bug.  I realize it might be important for Ubuntu TV
but if we will work on it we need some steer that TI would like us to do
that (and that we're not wasting our time vs the hardware capability).

Title:
  Panda: hdmi audio only on 2 channels

Status in Linaro Texas Instruments Landing Team:
  Won't Fix
Status in Linaro Multimedia WG project:
  Confirmed
Status in Linaro Ubuntu Evaluation Builds:
  Confirmed

Bug description:
  Installed the linarotv image 20120114-2 and hwpack_linaro-lt-panda-x11-base_20120106-1 on a Pandaboard ES with linaro-media-create.
  After boot installed ubuntu-omap4-extras-multimedia.

  HDMI connected to a Yamaha RX-V1800 audio-video-receiver and from
  there to a 1080p plasma.

  Verified multichannel audio with xbmc.

  xbmc settings:

  Audio output: HDMI
  Speaker Configuration: 5.1
  Audio output device: Defaults (ALSA)
  Passthrough output devive: hdmi (ALSA)

  1. when passthrough is enabled AC3 sound in videos does not work

  2. when passthrough is disabled only 2 audio channels are transmitted
  to the AVR (AVR display has indicators showing which channels are in
  use)

  Crosschecked with alsa speaker-test (speaker-test -c6 -t wav) with
  same result:

  Output correct for front left, front right and center (the latter only
  because the pro-logic decoder in the AVR puts sound equal to left and
  right onto the center) but rear sound is played with low volume on the
  front speakers.

  Situation remains after update/dist-upgrade on Jan 21. 20:45CET.

  Attaching the EDID sent by the AVR in case the audio capabilities are
  used by the driver (EDID is recorded with SwitchResX on a MacBook).
