Problems with Version 2.502

I’m having problems with Volumio version 2.502. Using RPI3, IQaudio Amp+ with Spotify and Airplay iPhone client. No sound at all. The volume scroll bar not working in web interface and Volumio 2 app on iOS and Android.

When I ssh into rpi and do a mpc volume the volume shows 87%.

Solved. Reset I2S device and reboot.
