This unconditionally returns 1 if the value written is in bounds which
means that an event will always be signalled. Please use mixer-test to
check for this and other issues.

This would be better written as a switch statement, there were some
other checks for variants that looked to have similar issues. It makes
it clearer that only one option can be selected and allows you to have a
default check that makes sure that any new variant with another AIF gets
handled.
