You probably need to unmute that with amixer (amixer set IEC958 100%<br>
unmute) or through the gui in mythbuntu.. There is a select controls<br>
tick box under audio properties, select iec958, and it will just start<br>
working.. No need to restart anything.<br></blockquote><div><br><br>alsamixer (a console gui) might also do it. <br></div></div>
