Thanks for your response. I am on kernel version <a href="tel:3.10.7-100" value="+13107100">3.10.7-100</a> fc18 and my<br>
alsa lib is alsa-lib-1.0.26-2.fc18.x86_64. Do you have any idea if this<br>
is the offending lib version and if so what is the best way to replace<br>
it with a new one. I have even tried installing a stand alone PCI sound<br>
card just to make sure it was not in internal motherboard issue and<br>
still no success. I have basically tested with all available sound<br>
outputs that mythtv give me and found that only the HDMI and analog<br>
outputs work.<br>

</blockquote></div>From what I can tell, you would need to upgrade to alsa-lib 1.0.27 to get S/PDIF to work again, or downgrade your kernel to 3.7 (maybe--your distro might pull in patches early). Look at this changelog section: <a href="http://www.alsa-project.org/main/index.php/Detailed_changes_v1.0.26_v1.0.27#Control_API">http://www.alsa-project.org/main/index.php/Detailed_changes_v1.0.26_v1.0.27#Control_API</a><br>
