Please help take a look at my issue.

“In macOS, when starting SPL measurement, the speaker cannot produce any signal sound.”

My REW,version is V5.31.3

The SPL meter shows sound levels captured by the selected audio input. It doesn't generate anything. You can use the signal generator to produce output signals.
