This may sound stupid but I have a bunch of downloaded sounds from Zedge. I had them on my last phone and was able to control the volumes. Ex. I have a Super Mario coin sound for my received text messages. I cannot lower the sound no matter how low I have the volume of my media, notifications/ringtone settings. I have even edited the sound using an app that allowed me to save it as a lower volume than origianlly downloaded. Am I doing something wrong or missing something?
