Memory Allocation Claims
All profiled memory snapshot of the non-allocation calls are made in Deep Profile with a project having the Incremental GC disabled.

Enabling the Incremental GC might add entries of 32 bytes logged as such Object.wbarrier_conc(), which is not coming from the AudioSystem.

Note that we are using warmed up pools and respect that boundaries when profiling, you might get different results if you use lazy initialization or a higher amount of AudioSource. You can tweak those settings in AudioUtils.cs.
