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.
I will add the code to check. return 0 if no need to be changed return 1 if needs to be changed Thanks.

sampling_rate);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.
OK, will send the patch to fix.
