I recently purchased a used Droid Turbo to replace my old one with a cracked screen. After getting the apps and everything set up the same as my old one, I noticed the sounds worked but were quiet. I assumed it was a phone problem and sent it back for another one. After getting this second one and getting to the same point, some sounds don't work at all. It plays the music when it boots up, and my ringtones, texts, e-mail work. However media sounds do not work at all (i.e. YouTube videos). I tried clearing the cache and rebooting, no luck. Does anyone know what I can check to see what's going on? I've checked all the obvious stuff. This is a Droid Turbo XT1254 running Marshmallow 24.91.5. My old phone is identical and running the same settings and apps and works fine. Thanks for any help.
