• AWS states that if the agent's audio device does not support up to 48 kHz while the browser asserts a 48 kHz sample rate, an audible humming sound might be present in the agent's outgoing audio, and that this has been seen with Firefox but not with Chrome. in context
• AWS's check for the humming symptom is to confirm, during a call, that input and output sample rates read 48000 under Media in Firefox about:support or on the Audio tab of chrome://media-internals, and to change the operating system sound settings or switch headsets if they do not. in context
