Does the Mi Box support aptX Low Latency for bluetooth?
If not, how are your experiences with video/audio sync over bluetooth on the mibox?
It's my understanding that aptX Low Latency support is crucial for streaming tv audio over bluetooth without delay.
i don't notice any delay issues when using my bluetooth headsets without aptx on the mibox, phone or computer. Mibox probably don't support it otherwise it would be mentionned
Despite owning a Mi box, I never paired it with Bluetooth headphones. But I have with a nvidia shield tv 2015, and here's my experience:
It doesn't support AptX. I noticed a definite audio lag, which can be fixed from within Kodi by displacing audio by around 200 ms.
Also I must say that even without headphones the audio sync isn't perfect, I bet it would benefit from pushing audio ahead by 50 or 100 ms. I mean from regular tv. But as we're not looking for it we don't notice.
I'm not sure if it supports aptX (probably not because of licensing fees) but I have experienced zero audio / video sync issues with any app using my bluetooth headphones with the Mi Box. This definitely was not the case with my first generation Fire TV Stick.
FYI, aptX isn't crucial for anything. It's rebranded 35 year old technology that may or may not provide any quality improvement over SBC. The lossless spec added to aptX is something cool, but that is supported by almost no devices.
