Alternatively make myth use a mixed output (e.g.
alsa dmix or pulse-audio), and have the computer
"keep the audio circuit open" (for want of a better
term). The pop is from your computer's output
turning on. Again, your ears have the final say.<br>

<div>That's the sort of solution I’ve been searching
for. I am using pulse-audio and I’ve been playing
around with alsa-mixer but I don't really know where
to go from there. Any tips?</div>

<div>Trial and Error seemed to support that something was
turning the sound card off when not in use and the pop was
caused by the card being turned on again.</div>
<div><br>
</div>
<div>If I start playing a recording within 10s of stopping a
previous one then no 'Pop'. Wait longer than that and I
hear the pop.</div>

<p>I had a number of audio quality issue with Mythtv and Kodi on a
system that had to use the mini audio analog plug to get the
signal to an amp without digital connection. I found a number of
solutions like HDMI splitters that pass on the HDMI, but split out
the audio into mini plug, Optical, and Coaxial digital. I've
notice no noise or popping on that solution.</p>
