Razer Seiren X - USB advanced audio device

Hello! I have been using the microphone for 1.5 years A week ago, when connecting, I decided not as usual - "Seiren X", but how - "USB advanced audio device" The sound quality became terrible, many settings in the drivers from Windows became unavailable Having looked for a solution to the problem, I realized, using the example of the same situation with microphones of other manufacturers, that the problem is in flown firmware, and you can solve this by flashing the microphone. How do I get software and firmware file? Thanks in advance! Text translated from Russian through google translate (I apologize for the errors)
