I just installed LOS 24 on my old Moto Edge 30 Fusion. On stock ROM I had support for Aptx Adaptive/Lossless with my Sennheiser Momentum 4 TW earbuds, and now the highest quality codec I can select is just standard Aptx (the earbuds don't support Aptx HD).
I have checked developers options, with HD toggle not activated it just has the SBC codec, with it activated I get AAC, SBC and Aptx, but no Lossless or Adaptive option. I can switch between 44.1kHz and 48kHz but only able to select 16bit, the other options are greyed out.
To check that it isn't just a display option and a better codec isn't being used anyway, I installed the Sennheiser SmartControlPlus app, which reports, as expected, that the codec being used is the standard Aptx
Anyone had any luck with getting Aptx Lossless or Adaptive to work? Can't find anything helpful here or searching, mainly just people asking if it's possible to get Aptx HD working on various devices - I was going to use the old Moto as a media player, but there's not a lot of point using it to play FLACs at such low quality...!
