Thanks in advance for any insight or suggestions. My preferred browser is Firefox. In Chrome, I can easily use a voice search from www.google.com. In Firefox, the permissions show my preferred mic as enabled and selected for that webpage -- but no sound is detected. (Using Firefox. mic works fine at https://www.onlinemictest.com.) (BTW, speaker output is Realtek motherboard audio and mic input is a Shure X2U USB interface. This mic works just fine in zoom, whereby, audition, etc. as well as working google.com using chrome) Have worked through various settings in the SOUND panel and SITE PERMISSIONS with no luck. Any ideas about this problem -- or what other settings to trouble shoot? Thanks!
