New Runtastic six pax no sound in 4.4.4 (xiaomi mi3 wcdma)

[xirixx]

I have a xiaomi mi3 wcdma, and I´m in 4.4.4. I´ve installed runtastic six pax and I don´t know how, but I can´t hear anything in this aplication, but when my phone was in 4.2.8 this aplication worked nicely and I can hear the explication and other sounds, but now I don´t know, why not. Can´t someone help me?Thanks
