That can work, but I'd rather check further why PA doesn't work with
Capture Source.  If it's something like an element that doesn't match
with the actual input, it's a driver's problem and we may work around
it somehow.  But before figuring it out, it's not wise to blindly
work around something just because it looks as if working.
