iOS 9 has many problems with playing sounds and these have been reported in the last few days by many users, certain application developers confirming their existence and blaming Apple in certain cases.
All problems appeared after installation iOS 9 in iPhone, iPad or iPod Touch, they persist in iOS 9.0.1 or iOS 9.0.2, so you don't have to think that an update will bring things back to normal because it seems that an update is not the fastest solution in this situation.
The first major problem is in the center applications that are no longer able to play certain sounds for users, specifically various sounds used by developers to amplify parts of games or sounds for dialogues seem to have disappeared completely.
Moreover, certain applications that use sounds to "communicate" with users no longer play sounds, and the developers mainly blame Apple and recommend downgrade to iOS 8.4.1, but unfortunately it is no longer possible at the moment for users.
Continuing, we have applications specially created for musicians who play distorted sounds or they play a "fasait" when playing certain sounds, the problem seems to be from the changes made by Apple for the APIs that allow the use of the speaker to provide functionality.
Finally we have applications that do not play sounds for notifications, and here the problem is extremely widespread and random, the sounds being sometimes played or sometimes not without any apparently specific rule and without any clear or permanent solution apart from a good update from Apple.
In the face of all these problems, we can only hope that Apple will take the time to solve our problems and allow us to finally use iDevices with all the functions that were intended for them in various applications and in the system of operation.
