Speaker recording doesn't seem to work for me on macOS Sierra 10.12.6.

not only macOS Sierra 10.12.6.

Speaker recording doesn't work on all macOS
can you help me?

the same to me with macbook air.

I can record but the generated video has no sound although I am using a workaround to detect silience on the stream.

In fact, on first attempt the stream comes with no sound (it is silient), so I release the stream and try to get userMedia againg that comes with sounds, but even with it the result recording has no sound on mac air on Chrome.

With a macbook Pro the record works and also the strem come silent in the first attempt but comes with sound on the second.

Below follow my console about the test:
