Audio input everywhere

[vlazzarini]

It seems audio input is not working anymore

• on Desktop (Chrome/Safari): request for mic permissions appears, is given but no sound input takes place. Contrast this with the example https://vlazzarini.github.io/vanilla/7.0/11.Rubber/ where audio input works correctly.
• on iOS (Safari): I don't see a request for mic permissions appearing.

I'm going to test this with a generic RMS Logger.

Report so far is no audio in on Mac Os 26.3.1 with Chrome Versione 146.0.7680.80 (Build ufficiale) (arm64)

The auth pop-up for Mic. permission appears but is not working.

thanks for checking. Note that this is not a problem with Csound wasm as I have tested audio input elsewhere and it works (see for example https://vlazzarini.github.io/vanilla/7.0/11.Rubber/)

Thanks for the update. Agreed, Csound wasm is working. After a quick look at the code base i suspect that the problem originates at init. Csound seems like started in a out only mode, so it suppress inputs.
