I don't know if there are any prior forums about this, but my eris does not play any sounds. It is supposed to play a notification tone, ringtone, a sound when choosing different pages and a sound when it turns off and on. It also doesn't play any multimedia sounds. Ive checked multiple times, and my silent mode is off and vibration mode is off. My ringer volume is also as high as possible, as well as my multimedia volume but my phone will still not play any sounds. Does anyone out there have any suggestions as to what I can do? Or is my phone defective?
