Isn't it anymore possible to use multiple notification sounds if firebase remote notification where used? Or do I have to create a NotificationChannel for each notification sound?
You have to create a NotificationChannel for each nofitication sound.
Notification sound can't be changed beacuse it's determined when creating the NotificationChannel. The properties you can update are the channel name and description.
@taito According to your business logic you can change notification sound.
Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notificationsound);
and then call to setSound(uri) in notificationbuilder.
