Please try to install pulseaudio manager. I don't remember the package name. Try synaptic.
Run it and check if pulseaudio runs.
From your output i see that somehow you are not in pulse-rt group. So the system does not allow you to use pulseaudio. I don't know why.
Try to add yourself to the pulse audio group
Code:
sudo adduser your-username pulse
sudo adduser your-username pulse-rt- Ooblivion - 2009-11-05 22:09
I added myself to the pulse and pulse-rt groups.
I then ran:
Code:
$ pulseaudio -D
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
E: main.c: Daemon startup failed.
$ pulseaudio --start
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.The pulseaudio manager was already installed on my system. I'm not sure what I'm supposed to do with it, though. I opened it and everything seemed to be working ok - but still no sound.
The speaker-test command still gives me sound output, but I can't any other way.
Maybe I should try the ALSA way in your tutorial instead....

@pregi
I got true-hd in stereo at first on my Onkyo after following the guide (no other mods) and then I had to select the LPCM multichannel mode on the Onkyo to get the full audio.
Hope it helps

As Ylagace wrote, you have to look for "multichannel lpcm" text on your receiver. Currently this is the way. You won't get dts-hd light up, cause your receiver gets the decoded stream.

@Ooblivion
Sure you have these custom files ?
~/.pulse/default.pa ~/.pulse/daemon.conf /etc/asound.conf
In PA manager could you please check the sink device pulseaudio uses ?

this guide looks seriously SERIOUSLY complex. will this work for a Live install? I'd like to get TrueHD audio off some of my rips, instead of DTS or AC3

I am pretty sure it works on Live. I'd go for the Alsa way. It could be good to make a backup of your system before try it. I recommend acronis true image home for this. But norton ghost is also good. This way you can freely make any experimentations.

Thanks for the info. I didn't really mean that it looks difficult to do, its just i don't know that much about linux, so it looks really daunting. I'll try doing a backup and then testing this when I get some free time

Hi alanwww1,
Just wanted to say my thank you's for this great guide you put together. My Onkyo TX-NR1007 just came in this week and I followed your ALSA steps with no installation issues on ubuntu 9.04.
I do have a small issue playing back mkv's with 7.1 flac audio created with eac3to. Center channel audio is coming out of the Side Left.
Any ideas? Have you tried any 7.1 source material?
Thanks again,
PBjr.
