Does not being allowed to give the adhaan over loudspeakers mean that the ritual of the adhaan is not being established?

If the Muslims are prevented from giving the adhaan over loudspeakers,
is this considered as being unable to manifest the symbols of Islam
and are they therefore obliged to migrate (make hijrah)and not remain
in that land?
Praise be to Allaah.
We put this question to Shaykh 'Abd-Allaah ibn Jibreen (may Allaah
preserve him), and he answered as follows:
This is not regarded as coming under that heading, because the use of
loudspeakers is a new thing. They can still give the adhaan with their
own voices and establish the symbols of their religion. And
Allaahknows best.And Allah knows best.
