Is there a way to choose what PC Audio source you wish to use in SmartSDR? I feel you should be able to accomplish this by selecting it in Smart SDR instead of having to set the device as your default audio device in Windows.
Am I missing something, isn't this a DAX question?
AFAIK you select audio in and out to a given slice in DAX, for example, see see instructions for working FT8 with WSJT-X software. From memory (I'm two hours from my flex) in SSDR you connect your slice to a DAX 'channel' then you direct your software to connect to the correct DAX 'channel'.
When im in SmartSDR operating remote I select PC for the mic source as I am using a USB audio device. The only way I can determine what the PC source is, is to set the device as your default in Windows. If you have multiple sound devices this gets to be a bit cumbersome. Very well could be operator error. I thought this would be a function of DAX too but really can see how you would configure it there.
