Hi Guys , I have been using Apple TV 4K for all the video and audio playback from my Plex server . Recently I have been collecting some Hi RES music and I became aware that the ATV only does 48 kHz Audio . So I used one of my Mac mini to listen to the Hi Res music , the Mac mini was handling every audio formats all the way to 24/192 KHz . But I realised the audio output volume of the Mac mini was lower than the audio output of the Apple TV . Both the ATV and the Mac mini is connected the the AV receiver via HDMI . So do you guys know why there is a volume difference?. Any kind of suggestions and help would be appreciated . Cheers. Emmany
