I more or less recently changed the alsa part of the jackd incantation
to have larger 'frames' (sorry if that's not the proper term) and a
larger number of them, which is now:

/usr/bin/jackd --sync -T -P80 -ndefault -dalsa -dhw:M1010LT -r44100
-p256 -n4

It was: -p128 -n2

Since then there are much less happenings/events of crackling. Which
would perhaps make sense since 'these' are larger and have more of them.
It still looks like a combination of user actions between using for
example firefox audio (youtube clips) while Bitwig is running (but
not playing audio) can throw the system in crackling audio mode at which
point a reboot is needed to straighten things back.

In this case, the problem is not constant and is created at the
software level. There is probably no relation between software actions
and pushing weak capacitors beyond their weakened limits.
