And my final comment on documenting this issue. It is completely solved in the current version of LineageOS, 20-20230803-NIGHTLY. Issues discussed above were in respect of a much earlier unofficial version of LOS, and version 2.1.5 GMS-less Android from Fx Tec. The current official LOS permits three codecs with these headphones, SBC, AAC and Qualcomm aptX, and they all work just fine, no sudden "suspend" disconnects. So thank you very much LOS devs, and mystery solved!

Playing with this a bit more, I see when I switch to HD Audio, two codecs are permitted with this combination of HyperX headphones and Pro 1x. They are SBC and Qualcomm aptX. By default, enabling HD Audio triggers the Qualcomm aptX codec, and that kills the headphone sound and starts the "suspend" problem. But it is possible to select the SBC codec instead of Qualcomm aptX when HD Audio is enabled, and that reconnects the sound. Interesting. Some kind of failure related specifically to the Qualcomm aptX codec. Anyone else have a Bluetooth device working properly, using that
