(S2S sample-codes/websocket-nodejs) different sample-rate is currently not supported

[athewsey]

When trying to "Start streaming" in sample-codes/websocket-nodejs, I get the following banner error in the browser:

Error: AudioContext.createMediaStreamSource: Connecting AudioNodes from AudioContexts with different sample-rate is currently not supported.

In the terminal, messages do suggest a stream is set up... But there's no audio interaction and after a little while I also see terminal log errors like the below:

Initial events setup complete for session {...}
Stream established for session {...}, processing responses...
...
Error processing response stream for session {...}:  ValidationException: Timed out waiting for input events

I was just trying to run the quick-start as per the README, and couldn't see any documented troubleshooting for this kind of issue? Observed with Firefox 137.0 on MacOS 15.3 (M2 Pro chip)
