I managed to get passed the stage above by copying and pasting the pastebin.
However I have now go to here:
Quote:We will unmute the needed channels and store these settings:
Code:
/usr/bin/amixer -q -c 0 sset 'Master',0 unmute && /usr/bin/amixer -q -c 0 sset 'Master',0 100
/usr/bin/amixer -q -c 0 sset 'IEC958 Default PCM',0 unmute
/usr/bin/amixer -q -c 0 sset 'IEC958',0 unmute && /usr/bin/amixer -q -c 0 sset 'IEC958',1 unmute
sudo alsactl store
and I get an error "Invalid Card Number"
Can anyone help?

Great guide! Helped me plenty!
Until now that i made a fresh install of lucid lynx minimal.
Seems impossible to install old Nvidia drivers anymore, it keeps installing nvidia-current that is 195.36.15 =(
Anyone able to help me? Uninstalling and running NVIDIA-Linux-x86-185.18.36-pkg1.run doesn't give me any luck anymore.

The end of the month and XBMC 10.05 is coming, Im planning to upgrade (or fresh install) to 10.04 LTS...
Any joy with the new Nvidia 195.36.24 drivers?
Still breaks Multi Channel LPCM output?

hey, i would like to link another post/question of mine if thats ok

Quote:Hey guys,
i am wonderung if someone got a, lets say more up-to-date solution for the HDMI Problem with Lucid and 10.04.
I am using an acer revo 3610 and after a fresh install there is until now no chance of having any sound with that system. i searched a lot, tried a lot and reinstalled often... My guess is that the guide from the first post is a bit out of date, e.g. that the default alsa version is 1.0.21. or am i wrong with that?
what is the problem with the 195ers drivers and HDMI sound? is it just to tell alsa which is the default sound output device? or is it still about rebuilding alsa? or is there something deeper not working?
One hope was this here: http://bbs.archlinux.org/viewtopic.php?pid=702657
but i think u can guess...
edit: whats about downgrading to nvidia 185 drivers? i didn't managed to get this working by now (maybe because i don't know how...)

So what I surmise here is that the HD blue ray audio streams DTS- Master, True-HD, etc. Can not be handled yet. Is That correct or did I misunderstand?
If there is any hardware/software combo (Linux or windows) that will handle the new HD streams, not decode them, just pass them on over HDMI 1.3, I would like to undertsand what they are and where to get them.
Thanks.

Is That correct or did I misunderstand?Hi Barry, nice to see you on another forum aswell. HD audio passthrough (bitstream) is possible when protective audio path is supported. As far as I've seen this means Windows + Ati/Intel/Cmedia/Auzentech + Arcsoft/PowerDVD/FFDShow.

Windows isn't really suitable for playing video (directsound is the reference clock which will give you framedrops, besides that there are to many different hwclocks), and those suites aren't capable of remote control or GUI like XBMC. So if you want to do what I think (kaliedescape like) they will not do great. MediaPortal does have an option to start an external player, but the TCP/IP options are to limited for me (besides the fact that it runs on Windows). And make no mistake a very pro Microsoft, but as a videoplayer it just won't do. But here is a MP thread about bitstream: http://forum.team-mediaportal.com/codecs-external-players-55/how-bitstream-dolby-truehd-dts-ma-within-mp-75571/#post555310
I do have another option, it's really easy and fast to decode DTS-MA and TrueHD to LPCM from script. And there isn't a bit that's different then when a receiver decodes it. I've got BD's with LPCM and DTS-MA, when I compare the original LPCM track with DTS-MA->LPCM they are bit for bit identical, as suspected because it's lossless. Downside is that you do need to rip when you want to watch a BD. But if you download movies, almost all BD's are also available as remuxes, most with LPCM track. If it's the increase in size that worries you, you can save them as lossless FLAC.
If you're going down this route maybe you'd be willing to work on an XBMC module together, you can have my current sources.
So everything short:
Windows isn't suitable for video with audio. Maybe some manufacturer will make a HW decoder like the old MPEG(2) decoders with audio.
Linux isn't suitable for protected audio/video content. Maybe someone will build something for it or you need to rip and remove protections.
MediaPlayers aren't suitable for nice GUI's and most aren't suitable for TCP/IP advanced control. Maybe the YUIXX or a future xstreamer product will.

You guy's are awesome! Can't wait to learn from this and try it out!

I had the same problem even with 1.0.22 I'm getting this Syntax error.
