I have several meta-strips with lots of sound strips in each. I want to edit one of these meta-strips, but when I playback the meta-strip from inside, Blender still plays all sounds from all other meta-strips. I decided to mute all meta-strips except from the current, but it did't help. Sounds are playing from all strips, even from muted off. Even if I mute all of the strips, sound is still playing (video behaves as expected, though). In 2.79 it works just fine. What happened in 2.80? Is it a bug or I missed some tiny option?
