FLStudio was open. I noticed today that I couldn't "Fast Sample Preview" anything from the browser so I reinstalled FLstudio on my computer. Now I have both issues where I can't listen to YouTube ...
sure if its a glitch from upgrading to the latest flstudio or maybe a plugin crashed from the last session. now when i re open any session it still wont allow me to use the slider/knob on the mixer plugins. - @slayinnrecords ...
