Yes that would. Apple still have to follow global supply and demand even if they do a lot of demanding. If there was a shortage of an audio interface, DAC or filter IC then it's inevitable that an alternative will be sourced to avoid final product shortages which would impact the bottom line.

There basically isn't a standard.
