<div>I was also missing the DMX controls (yes, four of them) until I installed the latest version of alsa. I'm running Fedora so I did the following:</div>
<div> </div>
<div># yum install alsa-kmdl-$KVER --KVER is the output of uname -r<br># yum install alsa-driver <br> </div>
<div>The four DMX controls showed up in alsamixer after this install.<br> </div>

<br><br>I have now looked things up a bit. I have S/PDIF (coaxial) connected<br>to my Harman/Kardon AVR-65, 5.1 receiver. Using Xine as player.<br><br>When configuring Xine's audio as "Surround 5.1" I looses the speach
<br>(center), all other sound works fine. Switching Xine's config to "Pass<br>through" I get a heavy cracking sound and no normal sound. Since I<br>want a pure digital signal to my receiver I think I should use "Pass
<br>Through", or?<br><br>One other thing I can see is that in alsamixer I don't have any DMX<br>controls. I have had them (4 of them I think) in a previous<br>installation. Shouldn't they be here?<br><br>What can be wrong?
