Tytung, When i connect the bluetooth to my Blue&Me system (FIAT car bluetooth system), the notification sound volume goes down, and also the TTS volume; I can't do nothing, the only way to recover the volume is do a call with bluetooth and than end the call, in this way your LowSoundFixer app restores the correct volume, otherwise i must restart the phone.
Can you please add to your LowSoundFixer also the following events?
- connect Bluetooth headset
- connect Bluetooth SCO audio
I found other users in other 4.2.2 thread that have the same problem.
