Ok, so the actual frequency is close enough to the nominal one. Please
also do the tests wit aplay to see whether your issue can be recovered
by chosing larger buffer sizes. Do you see any messages in dmesg when
these 'clicks and pop' occur?

Also, please try this one:

  (while sleep 0.123; do grep 'Momentary freq' /proc/asound/xxx/stream0;
done) | uniq
