This is driving me crazy and YES I should know better. No sound in Kodi (15 beta downloaded from minix site) on Z64 Android. Red mute in upper right hand corner during video. NO SOUND on any video file. I DO NOT KNOW what I did to mute video. HONEST. Audio goes through HDMI and is sent via optical to Vizio amplifier. But, it doesn't matter if I activate TV speakers still no sound. So.... I've tried everything to fix. Turned up volume in the devices, in KODI and pressed the A2 Mouse remote mute on and off. Go out to android in settings etc where volume is set and it is set to out HDMI for audio out. I go to Kodi turn passthrough on and off (I like passthrough)... COMPLETELY FRUSTRATED. Is this in the BIOS somewhere? How would the BIOS have changed and how do I get in there (if I should). FM on the z64 is current. Please help, where is it to restore sound. It does not matter how the sound is encoded. Thanks.
