Actually whenever in my z1, a notification appears like Facebook msg, WhatsApp, Gmail,etc. The sound of them comes like stucked sound, I am on latest fmw. 757.. I installed it freshly.
I hope you understand my bad description..
Edit. The speakers are fine, can test notification sound(from sound settings) and music no distortion,
But when I receive real notification then sounds like stucked sound..
