Hi, when using aptX Adaptive compatible TWS, randomly, sometimes after one minute of playback, sometimes longer, the quality starts degrading to the point of ending up with 1 channel mono sound that's heavily compressed.
If I switch codecs to regular aptX, SBC or AAC in developer options, the sound is perfectly okay. Also when I switch to aptX Adaptive, the Bluetooth sound - sampling frequency disappear and just display the "(default)" setting and there are nothing else options. I tried the WiFi and Bluetooth reset then restart my phone. I also tried to soft and hard reset the TWS device but nothing worked. I tried to turn off the TWS' high res audio mode too but the results are the same. I also tried different Bluetooth AVRCP and MAP-versions.
The TWS I use here is Sennheiser's Momentum True Wireless 3. I don't have any other item or phone that is aptX Adaptive compatible so can't really check on a different device.
I saw in some forums that it's not the TWS audio player device's problem but it's the phone's fault most of the time.

In the last pic I tried to turn the high res audio off too.
