Hi,

i try to get the spdif out of my motherboard Biostar GF 6100-M7 to work with XBMC. I think the problem is alsa, my motherboard or the spdif bracket but not xbmc.
I hope you can help me anyway .

Heres my configuration:
- Ubuntu 11.04 (Natty)
- XBMC pvr-testing (opdenkamp) VNSI (VDR works on an other computer)
- Motherboard Biostar GF6100-M7
- Geforce GT210 (for VDPAU)
- SPDIF bracket from MSI (http://www.msi-shop.de/spdif-bracket-433.html) connected to AV Denon Receiver with coax cable.

After a while i figured out that the connector of the MSI bracket has an other assignment than the motherboard.

MSI..............Biostar
1 Ground.......1 VCC
2 SPDIF.........2 SPDIF
3 VCC...........3 Ground

I changed that.

Stereo out works fine, digital out don't.
If i start the computer and xbmc, the av receiver switched to "digital", so i think the bracket works fine.
I note that, when xbmc starts a movie, the control "S/PDIF Playback" switched from 100% to 0% in alsamixer.

I have made several tries:
- read tutorials and .asoundrc files, but no one works.
- reinstall alsa
- changed settings in alsamixer

Here are screenshots of my alsamixer and xbmc sound settings.

Please help me, i hit the end of the road .

In short since I sent it already via email
- post a debug log via pastebin
- look for a bios entry (if any) and switch it from hdmi to spdif
- test via aplay to check if it works
- try using a HDA Intel mixer instead of the realtek one

(loosely vdrfan words)

Do NOT trust Windows devs when it comes to troubleshooting Linux issues ;D

Thanks for your help,

1. no extra bios entry for spdif, only Sound (disabled/enabled)
2. Test with

Code:

aplay /usr/share/sounds/alsa/Front_Center.wav
or
aplay -D plughw:0,2 /usr/share/sounds/alsa/Front_Center.wav

--> nothing to hear

Code:

aplay -l

Hmz, sorry i am out of ideas. The HDA is HDMI only so nothing you should worry about at this point.

Thats all I found http://hardforum.com/showthread.php?t=1102718
I followed some guides to get rid of all devices seen with aplay -l but - in my case - the hdmi device. Maybe the same works for you?

After i had tried to install alsa from source, no sound is working.
My next step was to install Windows 7 to try if the digital sound works.
The digital out works fine! But only the s/pdif, not the coax.
But with windows i got the problem that i can't play 1080p movies, the movie judder. :-( With linux (vdpau) it works.

OK, at this point i know my hardware is working fine.
My next step will be try to get xbmc with 1080p movies and vnsi run like clockwork.

Did you enable dxva2 in xbmc for Windows? Not saying you should giving up on Linux

[piet]

Hi,

i don't enable anything. How can i do this?

Edit:
OK, google is my friend ;-)
Found it at http://wiki.xbmc.org/index.php?title=How...or_Windows

[piet]

I enable dxva2 and it works with 1080p movies, but fast-forward is smoother with linux
Next try is to reinstall ubuntu 11.04 desktop (parallel with windows 7). Before i installed ubuntu 11.04 server.
