<p dir="ltr">I used to have a similar issue to what you are describing. I had to keep adjusting the sound synchronization. Then on a seemingly unrelated issue I came across this link:</p>
<p dir="ltr"><a href="http://www.mythtv.org/wiki/Frame_display_timing">http://www.mythtv.org/wiki/Frame_display_timing</a></p>
<p dir="ltr">My frontend was using usleep for its timing during playback but then I got the real time clock (RTC) device configured so Myth could run with it and now the playback is fully synchronized.</p>
<p dir="ltr"> Hope it helps.</p>
