func NewAAudioClientStub 

func NewAAudioClientStub(
	impl IAAudioClientServer,
) IAAudioClient

NewAAudioClientStub creates a server-side IAAudioClient wrapping the given server implementation. The returned value satisfies IAAudioClient and can be passed to proxy methods; its AsBinder() returns a *binder.StubBinder that is auto-registered with the binder driver on first use.

IAAudioClientServer is the server-side interface that user implementations provide to NewAAudioClientStub. It contains only the business methods, without AsBinder (which is provided by the stub itself).
