This is probably related to https://bugs.webkit.org/show_bug.cgi?id=284075 

But with the update of the WPT that added lots of PCM decoding tests, they intermittently fail on Ventura

for mp3 and Mac, a run in a Ventura VM showed that the AudioToolbox didn't support resampling content.

Those PCM tests are attempting to decode a single audio sample, and that seems to trigger an issue with our AudioSampleBufferConverter but only on Ventura

This bug aims at tracking on why.
