</div>If the sound is being carried VIA the graphics cable, then most likely<br>
you have two sound devices in your system. One is probably a standard<br>
Intel or Realtek HDA hosting your spdif. The other is likely<br>
associated with your video card. In mythtv's playback menus, make<br>
sure that your explicitly telling it to use the standard sound card,<br>
not the video card.<br></blockquote></div><br>There was also a change to ALSA in kernel 3.8 which broke S/PDIF. It was
about device numbering or something. It was broken in favor of fixing
HDMI sound, but I think a newer version of alsa-lib can fix it, but
you'd need to re-scan in myth. It may not solve your problem, but it
might be something worth exploring.<br><br></div><div class="gmail_extra">Karl<br></div></div>
