For me its more of "I can just use this dap for all my audio needs" rather than having to switch to my phone to use my BT iems. That was my biggest gripe with my Cayin n5ii, it only supported sbc and AAC and it had interference issues.
They never worked, because the device goes into sleep mode. It's hardware limitation, and can't be changed by firmware. The option is for volume control only, to block it during playback.
No it worked. I used it before the update.
It works on mine. It's all about the kernel and there shouldn't be such hardware limitation. I can use all the buttons when the screen is off or when I lock my device. On mango player, sometimes the first press doesn't do anything so I press again and I can use all functionalities.
Thanks for the advice. It’s going back. It is ridiculous that WiFi is so bad.
It is difficult with the way USB interacts differently. I have worked with different cable and some will work and some not. I think that there needs to be a real continuity in manufacturing but it hasn't happened. And wifi, I have found variables there with transmitters. Some work so much better than others. There isn't the continuity there either.
Only Power and Volume keys are connected to GPIO and can produce an interrupt to wake up CPU. Other keys are implemented via ADC which shall be polled to read their states, meaning, CPU must be active to sense them. So, once CPU goes to sleep, no a playback control key can wake it up.

};Yes I'm talking about screen off and music turning. I can't see the interest of using the buttons without music on. Maybe you can tell me...
To resume music playback after a pause, without a need to take the player off the pocket and turn screen on. It's an often complain.
Magisk developer said, he dropped support for Rockchip SoCs. But I didn't check myself what does he mean exactly. There is a little demand, but I can't say neither "yes" neither "no" for sure.
Just for the purpose to temporarily stop GMS, you can use System settings of my USB Audio application.
Ok I see and yes it could be helpful but understood it won't be possible...
