There's only three reviews in the App Store in regard to this app -- Sochi 2014 On Ten [URL="https://itunes.apple.com/au/app/sochi-2014-on-ten/id797283307?mt=&at=10l3Vy]https://itunes.apple.com/au/app/sochi-2014-on-ten/id797283307?mt=&at=10l3Vy&ct=vb_im[/URL], and going to the developer's site from within the App Store yielded a page 404 error. Having said that, I recommend that you uninstall and then reinstall the app. After that, go to through the iOS settings to find a way to set or adjust the sound for the app, if present. I also recommend that you go through the app's settings/options, if applicable and do the same. I do NOT have the app installed so I'm just offering blind suggestions.
