Bluetooth Audio works fine while using Apps over internet. It could be your internet issue. I have a 100 Mbps connection and I can stream 4K Video on YouTube while playing audio from Bluetooth speaker without any problem. |
But yes, with HDMI it's a disaster. I have been complaining about it from day one. HDMI Input > Mi TV > Bluetooth Audio is a disaster, crackling sounds, audio lags. Great TV with horrible software.
