That is simply false. Without the ferite layer there would be no resonance cavity to work with. Period. The fact helioseismology works at all SUPPORTS this model, it does not falsify it.
This is simply wrong. You stipulate you need a resonance cavity to get sound waves to pass through the Sun, and that is simply wrong. Sound waves will happily travel through a gas, even a relatively thin one (take a look at any supernova remnant filament for proof of that).

Your basis for this argument is incorrect. Helioseismology starts with the Sun being a gas, and shows that this can be used to "see" the far side of the Sun. You don't need a solid for sound waves to travel. You don't even need resonance of any kind. Just a medium that can conduct sound waves.
