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>
<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 never had a pop, but I missed the beginning of things like "You
have mail" (I would hear "ave mail"). Maybe my driver/audio
system has something on startup/resume to suppress the pop?
Anyway, that suspend-on-idle module is more for battery-operated
devices (laptops) and not real significant in a media center, so I
commented out the load line and I no longer miss the beginnings of
sounds.</p>
