le_thaadikkaran 0 Posted May 6, 2018 I have this firehawk fx, it was working fine... But suddenly, the master volume knob stopped working. I can change the master volume from the phone using the app but the knob is not working. I need a solution. Quote Share this post Link to post Share on other sites
pipelineaudio1 13 Posted May 6, 2018 If you press it will it switch to the other volume modes and work? Quote Share this post Link to post Share on other sites
