I have been experiencing this problem for too long. My music plays fine in any app. I've played it through headphones and Bluetooth speakers. The only problem I have is when I connect my phone into an auxiliary speakers. Let's say I'm using our home stereo sound system. The music playback keeps pausing and pausing maybe after every second playback when it is connected to the amplifier. So I can't play my music smoothly on my home speakers as it keeps pausing. I have a CM flare X. Playing through headphones and Bluetooth speakers is perfectly fine, though.
