There are a lot of different devices that run Android, with their own hardware configuration. This means sound loops may be handled differently from one device to another. If you hear sounds skipping periodically, or if they stop at times, you can fix this by changing the loop correction in Profile/Settings (More/Settings if you're on Amazon). Tap Loop Correction Mode and then select one from the available modes. You may have to try several modes before you find the right one for your device. Note that choosing None will deactivate sound looping.
If you continue experiencing issues with sounds, email us at firstname.lastname@example.org and describe in details the situation you're facing, so we can help you sort this out in no time.
