If you don't want OSS (pure alsa) change your Myth audio device to ALSA: iec958.

I have the Chaintech AV710 soundcard which seems like a popular card due to its price/performance. How do I get this card’s optical out to work with my Surround Sound Amplifier? Does it output 5.1 Surround? If so, what do I need to do to get it to work? I’ve read the MythTV Fedora HowTO and the links off that page in attempt to get the sound to work. I’ve replaced a zillion alsa sound files, but still doesn’t work. If I route the sound to PCM out, I can hear it off the Line Out port.<O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt; font-family:Arial"><O:P> </O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt; font-family:Arial">Thanks for your help!<O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt; font-family:Arial">Brandon<O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt; font-family:Arial"><O:P> </O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt; font-family:Arial"><O:P> </O:P></SPAN></FONT></P> </DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">mythtv-users mailing list</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:mythtv-users@mythtv.org">mythtv-users@mythtv.org</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users">http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users</A></DIV> <BR class="Apple-interchange-newline"></BLOCKQUOTE></DIV><BR></DIV></BODY></HTML>
