Show dependency between 'Also switch default device' and 'Communication' in profile dialog

[FireEmerald]

Describe the bug
If the user selects "Also switch default device" in profile without a device selected in "Communication" none error is shown.

Version
SoundSwitch v5.5.2

Expected behavior
A error message should be shown, as the Default device can't be switched without a actual selected one.
The dropdown should be only enabled if the checkbox is checked.

Screenshots

Additional Context
Seems like this configuration does not lead to a crash but the user may wonder why his configuration does not work.

That configuration works.  If you select nothing, the global device will be used for everything.  Setting the communication device is only useful if you want a different one than the global one.  Sent from Nine

I assume you mean with "global device" = "Playback". (-> yep)

I got your point but I think it would be a waaay better to say if the user wants to switch the default device he must define it. The current solution is to much "magic" in the background. At the moment you assume that the user knows what you know: If there's nothing selected in Communication the Playback device is used.

In addition, the dropdown field can still be edited, although the corresponding checkbox is not active - that's horrible. The dropdown field does not have any effect if the checkbox is not checked.

I'm not assuming anything, this is the way Windows works.  If you don't manually set a device as communication, it uses the default playback device. I reproduce the same feature.  For this one, I'm not going to change the way it works as this is already an advanced feature where you're supposed to know what it does already since you used in Windows.  Sent from Nine
