[BUG] multiple-pause-resume.sh should be deterministic

[lyakh]

Describe the bug
multiple-pause-resume.sh runs audio playback and capture while pausing and releasing streams at random times. This makes testing less reproducible.

Expected behavior
Random times should be replaced with deterministic ones.

Proposed fix
I propose to replace random times with a list of "pseudo-random" but fixed intervals. We could either use the pseudo-random number generator but with a fixed seed, or we can have a file with a list of "randomly picked up" prime numbers to be used as those pause-resume delays.

I'm assuming this is a duplicate of #694, explain and re-open if not.
