yes, happens to me too, and it happend to alex also, but you don`t need to restart the phone just play a video or a track and the sound will come back

the app it`s quite buggy but hey, it`s soo cool and i`m sure they will fix it soon, but i also think it will be in the app store, and we will have to pay for it because i use to have it on my old nokia phone and i had to pay for it
