Hello,
this is not a problem in mAirList, but in all probability Windows / driver related isuue, which affects my mAirList and other audio SW configuration though.
My config: Windows 10 Pro 64bit CZech, Behringer UMC 1820 soundcard (driver 4.38.0.0, the latest at the moment), Logitech C270 webcam, mAirList 6.1 + some other audio SW
I use Direct Sound / WASAPI sound drivers in mAirList and the other audio apps, which performs very well for me, no problem as far. Each input / output pair of the UMC 1820 is displayed as separate audio device in the Windows Sound Manager and in all audio apps I use (some of them are not capable of using ASIO drivers, that is one reason I use the DS/WASAPI, the other is that I run Thimeo StereoTool in ASIO mode on one I/O pair for some realtime processing, so I cannot use the ASIO mode in other apps, even if they are capable of it) . I have configured different ins/outs in each app as well as for individual players etc. in mAirList.
The problem is, that nearly each time I turn on or restart the computer, the Windows audio devices (i.e. in/out pairs) are in different order, as they were before the restart / power cycle. It means, that all the apps and players in mAirList are routed to different inputs/outputs than intended and configured before, so I have to reconfigure them all again after (nearly) each system start, which is pretty frustrating. The problem does not affect StereoTool, running in ASIO mode, as mentioned above. Aside that, the whole system works fine, stable, no exclamation marks in the Device Manager etc., using the latest drivers.
It seems, like the UMC is detected with a different GUID (or what, sorry, here my knowlege ends) sometimes, despite it is connected to the very same USB port and I do not make any changes in the PC’s configuration, nor connecting / disconnecting any devices etc., and the soundcard is powered on before the computer starts. (I anticipate that also from the fact, that in the Audio Devices Control Panel in mAirList the device is labeled differently from time to time, like (7 - BEHRINGER UMC 1820) one day and (2 - BEHRINGER UMC 1820) when I turn the computer on the other day. That is also probably the reason, that despite I save the Audio Devices configuration in mAirList, it cannot be correctly reloaded later after system restart, when the audio devices mess-up occures.).
Any help is appreciated, thank you very much.
P.S. I dont know if it helps, but these messages appear in the Windows Device Manager / Properties / Events dialog (sorry if the terms are not precise, it is labelled in czech on my system):
