Good, but troubleshooting.... – Police Siren & Lights Pt. Review

So I got this app and bought the extra pack or whatever a few months ago, and I like the app, the lights work well and all, but just recently, my sound hasn’t been working. Everything else works but when I play any siren it doesn’t make any sound. I have my volume and sound effects all the way up on my iPad, but still nothing. Can you please tell me what’s wrong? If you get back to me and can get the sound fixed than I will definitely increase my rating of the app. Thanks!
