Hmm. Unfortunately, I have no way of reproducing this at the moment.

@max-vogler @mzgoddard Do we have any M1 machines to test this?

Is there some additional logging I can enable to provide you with more details?

This might be helpful.

I built the extension locally and loaded the unpacked version. I had the Web Audio panel open while viewing a page that uses web audio API. In the extensions window I clicked on the red Errors button, and this is what I saw:

Then, I tried again just to be sure, and this time I did see a graph of audio nodes in the Web Audio panel. It doesn't look quite right, because there are no lines connecting the nodes:

While the page was running, I also noticed a lot of extension errors. I made a short screen recording, to capture them:

Perhaps there is an npm package being installed for the production build that is not compatible with Apple Silicon, but when I install (with npm ci) locally, it works. Sort of (missing lines, errors).

Thank you so much for the detailed reporting. We'll take a look at soon.

The dev team currently can't reproduce the issue. We'll take this on when we get M1 devices.
