Help is on its way.
Try the following:
1. Mute and unmute device
2. Adjust the volume on the device
3. Close multitasking apps not in use

I hate bugs as much as you do. If you see one please email me, and let me know what device and OS you are running. email@example.com
I'm intrested in how you use my apps and for any improvments you would like to suggest. Send your requests to me at firstname.lastname@example.org
