Running Remote-SDR on RPI 4 with Bullseye distro, running Debian Bullseye on PC.

Receive works, but when trying to transmit:

• No errors from nodejs console
• Latest Firefox (102.9.0esr) shows "SDR TX On" with green, microphone is selected, clicking on "TX audio on" makes button red, but no TX signal is shown on spectrogram. Firerefox does not pick any mic audio, there is error on console

  Uncaught DOMException: AudioContext.createMediaStreamSource: Connecting AudioNodes from AudioContexts with different sample-rate is currently not supported.
  Micro Stream not ready

  Changing sample rate from 10000 to 44100 in public/JS/remote_TX_audio.js solves this issue and transmission is performing, but with very noticeable delay and high CPU usage by python running gnuradio blocks.

• Trying with latest Chrome (112.0.5615.165), "SDR TX On" is shown with blue, clicking on "TX audio" button does not turn it red, mic signal is visible on spectrogram, so it picks up mic audio, but cannot start transmission
• Also in chrome "select frequency band" does not work, old band selections is selected back when trying to select new band
• Transmit works on RPI4 with, e.g. SDRAngel, GNURadio and command line tools

Google Chrome works fine for transmit. Haven't realized that pin code should be set in settings to enable transmit. Thank you.
