Okay I found someone on Linux has the same (functional) problem, using Bluez stack, but it turns out PulseAudio has this "set-card-profile" option that can be used to switch between HFP and A2DP. https://ansonvandoren.com/posts/pulseaudio-auto-bluetooth-hfp-profile/ Do we have something like this at sysctl level in the audio stack? Can this be set to auto-switch to HFP whenever microphone is opened and then reverted to default A2DP? -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
