No Sound w/o Headphones – LinguPinguin English Chinese Review

The app looks great, and seems great with headphones. There is no sound without headphones. Other game/video apps on my phone work just fine without headphones and I’ve closed all apps and rebooted my phone with no change. So, I’ve pretty much ruled out a problem with my phone. Please fix the app!
