there. I'm using Genymotion for test. I'm developing an android application. This application can make a sound. then I tried to test my android application. But,it would not make a sound.
My environment is Macbook. and Virtual box is 5.1. and VMDevice is Google Nexus 4 with API level 22. this would not make any sound even if i could change the volume of sound on genymotion.
And my virtual device setting is here.
