As a quick and easy solution -- quite likely yes.

Proper general solution for all of those laptops, and not only, would be
to rewrite the concept of default unit in sound(4) to allow it be
switched during playback/record, and separately for playback/record
paths. HDA driver is already able to provide all information about
connected devices, number of their channels, etc, but there is just
nothing above it to use that information. :(
