Example:
Power on USB DAC or bluetooth headphone = No change in listed output devices
In Windows 11, DFX behaves as if it recvs the hardware definitions from Windows and only asks once. Once per what?
So, I use irzyxa’s Volume² [systray shown] to right click and directly select output device. This switches the output AND refreshes DFX output device list. Once per what engaged but not identified.
It is reasonable to conclude that others use DFX in conjunction with a separate audio control with systray support. Those qualified users who recognize this guidance may or may not report duplicated results.
Therefore, once per what remains elusive. What causes the hardware refresh that DFX recognizes and how is it scheduled?
On multiple Win11 desktops, 99.44% compliance is achieved. From time to time, the HTPC does not read/write a signal but this could be a usage error. For the most part, everything switches correctly and I have not taken any recognized action to facilitate this. It just works.
But, I know better. I know that it is the juxtaposition of settings across multiple interfaces. Over time, my muscle memory has adopted a certain configuration of settings in the OS, certain TSR programs, device manager, and fxsound.
