Hi

I use Opensuse 11.1 64bit with alsa 1.0.18. I use a svn version of xbmc (SVN:19672).

I have huge trouble to get my onboard sound work with 5.1 analog output. When I run "speaker-test -c6" from console, right front channel is outputed to right front and left rear channel and left front channel is outputed to left front and LFE channel. When I run "speaker-test -c6 -Dsurround51" it hand when trying to play the first sound. When I try to play a file with 5.1 sound xbmc crashes 5seconds later. When I activate the option "downsample mutlichannel to stereo" it wont crash but there is no surround sound.

I now I had the card working but I don't know how. It is an onboard 5.1 soundchip (ALC662). I use the option "model=3stack-6ch-dig". I had it working with that model before.

I googled a while and I found a lot of people with similar problems but none solution is working for me.

Someone here can give me a hint how to solve this problem?

I'm having a similar problem (trying to setup XBMC to output 7.1 analog through my X-Meridian). If someone could write a guide for setting up XBMC with analog multichannel output it would be great.

I have done on e little step. When I play a mp3 with amarok (gstreamer output plugin) 5.1 output works!. I can mute single channels in kmix and the correct chennel gets muted. I can't understand why this works and xbmc or speaker-tes doesn't work.

For me this sounds alittle bit wired and I don't know where to look ...

I have an X-Meridian as well using 7.1 analog and 2nd the guide/faq request.

Thanks

My X-Meridian will output 7.1 analog witch perfect channel mapping using
speaker-test -Dsurround71 -c8 -twav

But no luck with XBMC

How do you guys see which devices you have?

[Katagia]

I take a look at kernel messages and alsaconf. Somewhere bewteen the messages you can see the device. Afaik its also shown in alsamixer.

I've updated to alsa 1.0.19 with no better result

/EDIT:

I was able to get the ac5.1 encoder from alsa working. With digital output I some nearly working sound, unfortunatly there are some glitches which sounds like buffer underruns ...

Statusupdate:
I've just compiled r20114. The sound issue is still there. Analog 5.1 output works well in KDE. In xbmc I'm only able to playback 2.0 sound. As soon as I want to play a file with 5.1 audio, xbmc tries to play a while (but there is no sound output) and than crashes after 5sec. It doesn't crash with digital output.

This is the debug output: http://pastebin.com/m602f8791
Unfrotunatly I doesn't have a backtrace because xbmc freezes.

With digital output I can playback the file. How should I proceed?

Cheers,

Just updated to alsa 1.0.20 and it is working again
