This could happen if you ever change the main audio device assigned as the Windows default.
Try rekordbox 6.6.6 and don't change any audio settings elsewhere, see if the preferences are retained.
Hello pioneer friends,
I use a rekordbox professional installation on my master pc to manage and sync my audio files.
In this installation on a Lenovo P50 Windows 10 64 Bit i am using my laptop audio drivers, with my USB interfaces from native instrument Komplete Audio 6 and another Alto live 1202 besides my usual DJ hardware.
I have a very annoying little probem with this installation.
After each program start I have to set the audio again. After starting the program it looks like the picture and I get no sound. Until I just set the setting new then it works again. Unfortunately, I have to do it all over again. The setting is not saved. What is the reason, how can I fix the Probelem.

After setting everything runs but I always have to set it again at every program start.

I hope that someone can help me with my other installations everything works but not with this one. And I do not know what the reason is.
Kind Regards David
