[Solved] I hope. I swapped out audio drivers. But trying to connect to a video meeting in Firefox I get this error: "unable to subscribe to stream in a reasonable amount of time". It works in Vivaldi though. Anybody know why is that and how I can fix this in Firefox? ___________________________________________________________________ PC integrated mic: silent, intermittent, screeching or sharp feedback. Posted in software because I'm hoping it's a software not a hardware problem. Lenovo e540 W7P64 I must add the microphone worked up until 2-4 weeks ago. So if more details are needed please let me know.
