Peter -- Please add the following Nvidia Shield Setting to your
Digital pass through documentation. You might label it as
optional if people have problems locking the correct codec. The
problem may be exclusive to older receivers.

<div>Michael, John, Tim, James - All of you have talked about
audio problems recently with the Nvidia Shield in this or
parallel threads. Investigate the feature below. It might
solve your problem.</div>
<div><br>
</div>
<div>I've solved my issue with my older receiver not locking on
to the correct audio codec when starting a new recording and
sometime after a commercial skip in the middle of a
recording. In these instances I get no audio other people
have report similar odd behavior. A pause/play or a skip
fixes the issue but its very annoying. After turning off the
following Nvidia Shield Setting (not in Mythtv) everything is
working correctly. Note that the very first time using
MythTV after the change I got odd behavior. You might need to
restart MythTV or even the Nvidia Shield. </div>

Not really sure what the setting does but turning it off fixed
my issue. There must be something non-standard with the way
MythTV integrates with Nvidia Shield audio that causes
issues. No other apps I've used have had issues. <br>

<p>Hi Jon,</p>
<p><br>
</p>
<p>Thanks for the note. This morning, I did turn off that feature
(without rebooting the shield ) and it DOES seem to have
eliminated the sound issues I have been seeing. This will
indeed raise the shield acceptance factor in my household a great
deal. That noise drove my wife/daughter crazy and they were
lobbying for me to bring back to old frontend and get rid of the
shield.</p>
<p><br>
</p>
<p>I am not sure when this feature was introduced. I didn't have
any sound issues on Shield 7.0, then it started in 7.1 and
continued into 7.2. <br>
