Hi,

For what it's worth, here is what I got when running the new AE trying to get HD sound.

Hardware:
- A75M-UD2H Mobo with 8 GB
- AMD A6-3500 APU
- GT 630 with 2GB (Replaced my HD6870-based as per first post)
- Marantz SR6005 connected via HDMI

Software:
- Ubuntu 12.04. Boots directly into XBMC, no display manager, no pulse audio
- XBMC Frodo alphas 3 (wsnipex ppa)
- ALSA: kernel reports 1.0.24. utilities 1.0.25
- nvidia driver 295.49-0ubuntu0.1

AV material: (Accessed over NFSv4)
- Chicago V, 2 ch 192kHz 24 DVD-A rip FLAC
- Chicago V, 5.1 ch 96Khz DVD-A rip FLAC
- Various Ogg, FLAC
- In the line of fire BD rip, TrueHD and AC3 audio, mkv container

Initially, all my HD sounds were down-mixed to 48kHz, as it turned out I MUST boot my XBMC box when the receiver is on and XBMC box is the active input. Here is what I got when booting with the XBMC box not the selected channel on the receiver

Code:

john@Hollywood:~# cat /proc/asound/card1/eld#3.0
monitor_present         1
eld_valid               1
monitor_name            marantz-AVR

connection_type         HDMI
eld_version             [0x2] CEA-861D or below

support_hdcp            0
support_ai              0
audio_sync_delay        0
speakers                [0x1] FL/FR
sad_count               1
sad0_coding_type        [0x1] LPCM
sad0_channels           2
sad0_rates              [0xe0] 32000 44100 48000
sad0_bits               [0xe0000] 16 20 24

As you can see:
- The receiver is detected and the brand recognized (Great!)
- The maximum sampling rate is 48 kHz (oops)


With the XBMC box booted whilst the selected input of the receiver I got:

Code:

john@Hollywood:~# cat /proc/asound/card1/eld#3.0

sad6_channels           8
sad6_rates              [0x6c0] 44100 48000 88200 96000

Much better.

Result:

Various OGG,Flac: No problem
2 ch 192kHz: No problem
5.1 ch 96kHz: Worked good but XBMC frozen during one of the track change (system OK can ssh into it).
I saw that problem before, it is probably not an HD sound issue
AC3 : No problem
True HD : Does not work. The sound and image alternate between too slow and too fast. Changing the audio stream
to AC-3 solves the issues

I need to do some more testing: upgrade ALSA, downgrade NVidia

Anyway thanks guys, we are almost there.
