Check the alsa ucm profiles under /usr/share/alsa/ucm2/ to see if it matches the change you're seeing. If so you can edit the profile to something that suits you, but it'll get reverted the next time there's an update to the package that installed it.

Thank you.  I adjusted the capture in the alsa ucm and that solved it; until as you say, a package update sets it wrong. 
But now I know where to configure it.
