Why is audio recording using WebAudio API not working in Firefox using a 22kHz USB audio device?

USB audio devices with 22kHz sampling rate don´t work as audio recording devices in Firefox using WebAudio API (e.g. https://webaudiodemos.appspot.com/AudioRecorder/index.html). 16kHz and 44kHz devices work fine. However, in Chrome, all of them work fine, regardless of the sampling rate. Can this be fixed?

Do know that Microsoft can and will change your hardware drivers. (happened to me 5mins after updating my sound card drivers.) Check in Device Manager to see if any changes have been made. https://www.howtogeek.com/302595/how-to-stop-windows-10-from-automatically-updating-hardware-drivers/

Thanks for having a look into my issue. However, none of your suggestions solved it. Microsoft provides hardware drivers for my USB Audio device (it´s a Philips SpeechMike) anyway, so it can´t change drivers I have installed (because I never did that). It´s just, WebAudio in Firefox works with 44kHz and 16kHz devices, but it does not work with 22kHz devices. Chrome works with all of them.
