Hi all,<br><br>OK further testing...<br><br>I have tried adjusting the settings as per the below<br><br><div class="gmail_quote"><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<div class="gmail_quote"><div class="Ih2E3d"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div style="font-family: 'DejaVu Sans'; font-size: 10pt; font-weight: 400; font-style: normal;">
In your Frontend end setting what sound selections do you have? (Setup|General), around page 3<br><font color="#888888"><br>
</font></div></blockquote></div></div><div class="Ih2E3d"><br clear="all">Audio output device: ALSA:spdif<br>
Passthrough output device: ALSA:iec958:{AES0 0x02}<br>
Max Audio Channels: Stereo<br>
Upmix: Passive<br>
Enable AC3 to SPDIF passthrough (checked)<br>
Enable DTS to SPDIF passthrough (checked)<br>
Aggressive Sound card Buffering (UNchecked)<br>
User internal volume controls (UNchecked)<br><br></div></blockquote><div><br>And this has not improved the result. Still no audio. To ensure it is not a problem with the TV playing dolby digital sound, I have now routed the hdmi signal through my home theatre receiver. The result is the same.<br>
<br>I have also tried `alsa:device=hw=0,3` or `alsa:hw=0,3` but this also made no difference.<br><br>I am not sure if this provides any clues or not, but trying to play my mp3 collection through MythTV also fails with no sound, yet using vlc plays them without issue. Does mythtv share the same play mechanism for these two file types?<br>
<br>Also, I retried playing the original recordings via an NFS mount using aplay and they play without issue and with audio. I must be sending digital audio as I have no other audio cables between the two devices.<br><br>
I also downloaded a DD5.1 audio test clip and played that via aplay and my receiver picked it up correctly and played sound through each of the speakers in turn.<br><br>To me, this would indicate that my mythbuntu installation is working for hdmi digital audio without issue. MythTV however is not...<br>
<br>What further information should I provide to try and figure out why this is happening?<br><br>Cheers<br><br>Phil<br></div></div>
