Hello everyone,
I hope you are all doing well. I am reaching out to get some technical advice regarding an audio driver issue we are experiencing while integrating a Mackie DLZ Creator mixer into a 24/7 online radio station setup.
The station runs 24/7 on a dedicated Windows 10 PC running RadioBOSS (active license). Since live hosts are only on the air during specific time slots, the studio requires the Mackie DLZ Creator to be turned on only during live shows and powered off afterward to prevent unnecessary wear and energy consumption.
Whenever the mixer is powered off and turned back on, RadioBOSS (and Windows itself) completely loses the audio endpoint from the console's USB interface. The sound does not return under any circumstances.
Best regards,

Since live hosts are only on the air during specific time slots, the studio requires the Mackie DLZ Creator to be turned on only during live shows and powered off afterward to prevent unnecessary wear and energy consumption.
Whenever the mixer is powered off and turned back on, RadioBOSS (and Windows itself) completely loses the audio endpoint from the console's USB interface. The sound does not return under any circumstances.
- Closing and reopening RadioBOSS during a brief pause does not restore the audio.
- Restarting the computer fixes the issue and restores the sound, but rebooting the entire system is not a viable option for a continuous 24/7 broadcast operation.
- Windows USB Power Settings: We have already disabled USB selective suspend in the Windows advanced power options to ensure the OS isn't putting the USB ports into an unrecoverable low-power state.
- Audio Driver Modes: We suspect this is related to how WASAPI handles endpoint persistence. We tried switching to ASIO, but it did not prevent the disconnection issue. Furthermore, using ASIO prevents us from utilizing the RadioBOSS PFL (Pre-fader listening / CUE) output, which is an essential feature for our workflow.
- System Audio Behavior: We noticed that when the mixer is power-cycled, Windows 10 system audio itself fails to recover on that device. This suggests that the Mackie DLZ Creator driver does not reinitialize properly within the OS after a physical/electrical disconnection.
- Virtual Audio Cables: We attempted to route the audio using VoiceMeeter and Virtual Audio Cable (VAC) as a bridge so RadioBOSS would never "see" the hardware disconnect. However, the issue persists at the physical endpoint level.
- Windows 11 Behavior: Interestingly, we tested this setup on a Windows 11 machine. On Win11, if we power-cycle the mixer and then restart RadioBOSS, the sound does come back. However, restarting the automation software at every shift change is still not an ideal solution for a seamless broadcast.
