When I try to play a movie with digital audio, it seems to want

Did you follow the instructions in the ticket?

<p>Hi Peter, I am finally updating to version 31 this week and had
saved this thread for when I was able to do the upgrade. In the
notes of the ticket you noted:</p>
<p><br>
</p>
<h2 id="TouseAudioTrackonAndroid">To use AudioTrack on Android</h2>
<p>
In the Android setup, choose "Automatic" or "Best Available".
There is no need to force Dolby Digital in Android, it will be
used automatically if your hardware supports it.
</p>
<p>
Select "AudioTrack:" audio device. Enable all entries under
"Digital Capabilities" and set the appropriate number of speakers.
Android will detect whether your TV or sound system supports the
audio format and will either pass it through or decode it within
android hardware. So for example you can select Dolby Digital even
if your sound system, TV or display monitor does not support it
and android will decode it. If you do not select the checkbox,
MythTV will decode it.
</p>
<p>
I have tested Dolby Digital (AC-3). I cannot test multi channel
LPCM, DTS, E-AC3, etc. If anybody can test these it would be
appreciated. In particular, testing multi-channel LPCM is needed
to make sure the channel mapping is correct.
</p>
<p>
Let me know if there is any feedback. <br>
</p>

<p>I configured my shield frontend to have all digital formats and
set the Shield to auto. It seemed like all was working until
today my wife reported a video that has AC-3 audio that wouldn't
play any sound. If I uncheck AC-3 in mythtvsetup, I get the
audio. Additionally, in leanfrontend it plays with audio just
fine.<br>
</p>
<p><br>
</p>
<p>According to the manual for my receiver, it does support all of
the digital audio formats in the mythtv screen.</p>
<p><br>
</p>
<p>Are these instructions still accurate? Any thoughts on debugging
further?</p>
