- Kali - 2009-11-04 @ylagace there is no free dts-hd codec, only True-HD track are comparable - pregi - 2009-11-04 how did you get true-hd working via hdmi with this guide? i just got stereo output on my denon 4308 - Ooblivion - 2009-11-05 I'm running my HTPC through hdmi directly to my TV. My HTPC setup is in my sig. Using the settings of "plugin:hdmi" and passthrough of "hdmi" I was able to get audio when I played a movie or a song. But nothing else. No gui sounds, no sound when running huludesktop, etc. So I thought I'd run though this tutorial since I'm not much of a linux guru and see if I could get that to work. First, I upgraded to the latest NVidia driver: 190.42. Then I followed the setup for the PulseAudio way (since I wanted gui sounds and sounds outside of xbmc). And now I don't have any sound at all. Maybe since I'm not needing multichannel, I shouldn't have tried this setup. Should I remove this setup, i.e: Code: rm ~/.pulse/default.pa ~/.pulse/daemon.conf /etc/asound.conf Any help would be greatly appreciated! Thank you! - alanwww1 - 2009-11-05 Hi Oblivion ! Are you using "default" in xbmc as audio device ? Disable passthrough there. Have you checked pavucontrol utility if pulseaudio is working properly ? What happens if you try Code: speaker-test -Dhw:0,3 -c2 in a terminal. You can revert the changes removing those files. Note that my guide is for Ubuntu Jaunty at this time. Have you upgraded Alsa ? What is the output of Code: aplay -l and Code: aplay -L - Ooblivion - 2009-11-05 Thank you for the very quick reply, alanwww1! Quote:Are you using "default" in xbmc as audio device ? Disable passthrough there.I am using default in xbmc and set passthrough as "custom", with nothing filled in. There is no audio when I run a windows manager, like gnome, either. Quote:What happens if you try: speaker-test -Dhw:0,3 -c2 in a terminal.Well, what do you know. That worked! At least I got the sound coming out of the right and left speakers of the TV while running gnome. Quote:Note that my guide is for Ubuntu Jaunty at this time. Have you upgraded Alsa ?I am using Ubuntu Jaunty and my Alsa version is current: Code: [color=blue]$ cat /proc/asound/version The outputs from a terminal are: Code: [color=blue]$ aplay -l and Code: [color=blue]$ aplay -L I setup gnome to use pulseaudio as you showed in your tutorial. But the "test" buttons on the audio setup didn't produce any sounds. You mentioned at the beginning of the pulseaudio setup: Quote:If you want to use Pulseaudio with dedicated htpc setup, like xbmcbuntu, you must install pulseaudio package first. Probably you also have to put pulseaudio -D in your xbmc startup script. Do I have to manually startup pulseaudio? Do I need to put "pulseaudio -D" in my xbmc setup script? When I run in a simple terminal, not in gnome, I get: Code: [color=blue]$ pulseaudio -D If I run with sudo: Code: [color=blue](T: XBMCLive)xbmc@XBMCLive:~$ sudo pulseaudio -D Sorry for the long post. And thank you again for the help, alan. - alanwww1 - 2009-11-05 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 - Ooblivion - 2009-11-05 I added myself to the pulse and pulse-rt groups. I then ran: Code: $ pulseaudio -D 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.... - ylagace - 2009-11-05 @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 - pregi - 2009-11-05 @ylagace thanks. ill try this - alanwww1 - 2009-11-05 pregi Wrote:@ylagace 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. - alanwww1 - 2009-11-05 @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 ? - Evanrich - 2009-11-06 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 - alanwww1 - 2009-11-06 Evanrich Wrote: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. - Evanrich - 2009-11-06 alanwww1 Wrote:I am pretty sure it works on Live. I'd go for the Alsa way.

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 - pbjr - 2009-11-06 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. |
