[PROBLEM] Airplay stuttering since moOde 9

[cramcram]

I wanted to give a quick update on the testing I did related to this issue:

• First, I swapped the SD card to rule out a faulty card as the source of the problem - the issue persisted.
  
• Then, I downgraded from a Raspberry Pi 3B+ to a Raspberry Pi 3B - the issue persisted.
  
• Finally, I upgraded to a Raspberry Pi 4 that I still had lying around - voilà, the issue is gone, and Airplay works flawlessly.
  

So, it seems the problem is related to the Raspberry Pi 3B and 3B+ models. For each of the steps above, I performed a fresh installation of Moode 9.2.0. The issue, at least in my setup, is reproducible.
