If you use firefox for hamradio like openwebrx or kiwisdr the Sound will die after a Update!
That’s NO Driver or NO Linux or a WEBSDR Problem, The Problem is DISABLED AUDIO startup on Firefox
Fix:
- Enter at the URL-BAR „about:config“ search entry „media.
autoplay. block-webaudio“ to false - Restart Firefox and be happy..
- If you are a Security Nerd then use 2 Firefox Profiles for Web and different for SDR-Radio..
