I ended up buying a new HDMI amp.. Now fully supports all sound
codecs..
I think i need to disable pulseaudio as it does not support
passthrough.
Thanks for your help!

Hi All,
Hello,
I've been trying to configure my Shuttle
XS35GT (ION2 HDMI) with ALSA (without pulse as I want
pass-through) for the past 2 days. I'm using Ubuntu 10.10 and
have now compiled nvidia drivers and alsa from source code on
kernel 2.6.35-24-generic.
I too have got an XS35GT, and I have sound over HDMI working
satisfactory (for my purposes, at least).
Running Debian unstable, I have compiled my own kernel (2.6.35.4)
and I use the latest Nvidia drivers (260.19.29) which I
re-installed yesterday.
It's connected via HDMI to my Philips 47PFL7404H/12 TV. Philips
seems to be making the only TVs on earth that can take 5.1 audio
from HDMI and pass it on to my 5.1 receiver, using a coaxial
S/PDIF cable. All other TVs seem to be downmixing to 2.1 or 2.0
before sending audio on to a receiver through (optical) S/PDIF.
I cannot for the life of me get it
working... I can play standard sound like "speaker-test -c 2 -D
plughw:1,7" but when it comes to speaker-test -c 5 -d plughw:1,7
it throws "xrun_recovery failed: -5,Input/output error"
Same thing for me, which surprises me since I do have 5.1 sound
working when playing DVDs etc. through mplayer.
Also, when testing mplayer with an AC3
encoded sound file it throws

I too get similar error output, but I still get 5.1 audio (just
tried with my Bjork "Volta" 5.1 DVD). My mplayer command, as
you'll see in the attached mplayer_tv_real.sh, is basically this:
$ mplayer -ac hwac3,a52, -ao alsa:device=hw=1.7 dvdnav://
and I just discovered that hw=1.3 and hw=1.8 works just as well,
but for some reason hw=1.9 is mute. I see you use hw=0.7, try 1.7
instead.
I've attached aplay -l and aplay -L output
in the aplay.txt file.
Driver is loaded with options snd-hda-intel enable_msi=0
Same thing here, according to my /etc/modprobe.d/alsa-base.conf .
I've read 1000's and 1000's of posts and
tried alot of "fixes" but nothing has worked.
Any help would be much appreciated!
I have attached output from "aplay -l", "aplay -L", "dpkg -l"
(gzipped), and "zcat /proc/config.gz > config" (gzipped), as
well as my $HOME/.alsactl.store (generated with "/usr/sbin/alsactl
-F -f $HOME/.alsactl.store store"), /etc/X11/xorg.conf, and
/etc/modprobe.d/alsa-base.conf, plus two scripts I use to run
mplayer (mplayer_tv.sh calls mplayer_tv_real.sh, as you will see).
Hopefully looking through my working config will help you come
closer to audio working the way you want.
The XS35 is a really nice piece of hardware, but DVDs do tend to
get hot when played, and the LEDs on the XS35GT are annoying. And
I really think Shuttle should have included an optical or coax
S/PDIF output, but since they didn't I have bought a Sweex SC016
USB 7.1 soundcard, to be able to listen to stuff in 5.1 without
having to go through my TV. Haven't hooked it up and configured it
yet, though...
