do not blame the cat!

i have same setup:  
-a- RPI Raspbian  
-b- HDMI TV/Monitor with sound  
-c- processing 3.5.3

* * *

now that funny noise from the speaker i also have!  
but only when i play  
[p5js.org](http://p5js.org) like sketch  
[p5.js Web Editor](https://editor.p5js.org/kll/sketches/rkIQz9LhQ)  
! and only as long i am LOGIN!!! ( very spooky )  
pls listen in:

the noise seems related to drop in FPS ( that’s why i choose this example )

if login i hear that noise!

@kjhollen any idea why login lets the FPS drop like that? server communication would be only required on menu operation??

* * *

with that in mind i open processing 3.5.3  
in p5.js Mode  
copy paste same sketch and run it,  
but not hear anything.

* * *

in both that is not a sketch what use any sound lib.

when i use processing 3.5.3 in Mode p5js  
and test any “p5js example sound” it works.  
but i see the red warning

> no content type found for .mp3

* * *

when i use processing 3.5.3 in Mode Java  
and test example from Minim ( all P3D )  
there is a 5 sec start delay for the sketch but  
then the sound play fine.

* * *

oh yes, RPI settings!!!

- i use the GLdriver Legacy / not KMS
- memory split is on 128
