Everything seems to work fairly well with ALSA only.
The only way I can reproduce an identical crackle, and aside of the
re-setting of jackd buffer size (but that makes apps die as of jack
0.100.0), a way to try to restore a crackling jackd is to use the
"pound" script I posted before:
#!/bin/bash
# Pound on broken TV set
sudo jack_simple_client POUND! &
sudo kill -STOP `ps -el|grep simple|awk '{print $4}'`
sleep 0.2
sudo kill -CONT `ps -el|grep simple|awk '{print $4}'`
sleep 0.1
sudo kill -9 `ps -el|grep simple|awk '{print $4}'`
But this produces all sort of noises while operating (while kill
-STOPping jack_simple_client) and sometimes makes jackd die...
