Oh damn I'm just a bit to late for that Wink

But the Alsamixer was looking good with those S/PDIF channel's? If I'm only using HDMI?

harryzimm · 2010-05-29 15:37

Yep. Its exactly the same as mine.

Great going to install it again

I'd like to keep me busy haha.

ps. your Avatar make me thinking of this song Shed my Skin

Harryzimm thanks so much again Wink

It's stable and working great.

I assume you noticed that if you config it like this the receiver will no longer show PCM Multi Channel but Dolby Digital 5.1 if you play FLAC.

Can you clear this out for me please? I think it's all fine if it isn't down streaming the bit rate.

harryzimm · 2010-05-29 17:22

no problem.

I dont have any FLAC files to test unfortunately. Do you have a sample? Also try disabling dolby digital capable reciever in audio settings. My reciever accepts dolby and dts but i disable them anyway so xbmc sends pcm instead. The reason bieng i need xbmc to resample the audio so it can sync playback to display. (my plasma wont do 24hz).

cheers

I'm so happy !! I'm so happy Tralala lalala lalaaaaaaaaa Big Grin

I'm turning it off for sure. PCM Multi is working and the sound it much better then when I let my receiver do the work Eek

And for the final even Avatar (40GB) on the space part doesn't give any juddering no more Shocked

Thanks you so much for your time and help!

harryzimm · 2010-05-29 17:45

No problem i'm glad its working Smile

PCM Multichannel on Lucid with Nvidia 256.25 (Judder proof)

With special thanks to Harryzimm!

First I'd like to thank everyone here for there work.
Took me a bit of reading but I now have full Multichannel PCM from my Revo Big Grin

Now to my question, and I appologies if this has been covered before but its a rather big thread.
Is there any way to push Stereo content as 2 channel and not Multi so my amp does the PLII upmixing?
