Another thing that would be nice to try would be:

try with one of the pipelines above the have crackling to
set the buffer-time and latency-time properties of alsasink.

You can do so by writing instead of "alsasink"
"alsasink buffer-time=200000 latency-time=10000"

Try using higher values than these and please report if this makes
any difference.

Thanks
