Hi there,
My macbook pro 14 in m1 makes cracking sound while music is playing when the memory pressure is yellow (shown in activity monitor). However, when I reduce the memory pressure to green, the cracking sound goes away.
Is this a hardware issue that I need to return my mac? Or, this is a software issue that can be fixed after the next update?
Thanks a lot.
MacBook Pro 14″, macOS 12.4
It is Prudent to run the diagnostic as suggested.
If no faults are found, remember that Smooth sound generation requires the continuous attention of the processor, which cannot occur when you allow your memory situation to deteriorate into the yellow Zone. Your Mac is busily shuffling stuff in and out of RAM memory, and compressing and de-compressing blocks of memory, and can not provide the complete processor attention required for smooth sounds.
Quit unused Applications and avoid so many memory-intensive tasks if you want smooth sounds.

Hi ColleenD1,
I tried the diagnostics steps you suggested. No issue was found. Is this some unknown hardware issue or it's a software issue?Any further advice? Thanks.
Hi Grant Bennet-Alder,
When I tried it with my bluetooth speaker, no such issue was found thought. Any advice? Thanks.
