How do you ask for low latency with aptX Adaptive?

How do any given headphones know if I'm gaming or listening to music, and therefore what latency/quality ratio might be best? Can I specify somehow? Thanks

aptX adaptive has a latency of about  80 ms according to Qualcomm.
This latency is fixed.
The adaptive part is the bit rate (279-480kbs) but this is about the stability of the connection, not about latency.

Ah you're right.

I also just read that aptX Adaptive isn't really compatible with LL either, as it reverts to regular aptX mode when connected to a LL device. Does that mean that Adaptive (80ms) isn't as good as LL (40ms) for latency or is there more to it? It seems strange that Qualcomm would retire a technology that they haven't full replaced.

AFAIK, that's that. If you want that low latency you need to have LL-capable hardware, on both the PC and the headphones.

Things should improve in the future with Bluetooth 5.2, which uses a lower latency codec by default.
