Well, that.
What i need to install?
I have a DAC connected to my pc, and want to use it to receive from the cellphone to the pc (im using a bluetooth usb dongle).
In the pc i just use ALSA.

You need your PC to act in HFP mode for the phone. I'd generally reccommend you use pipewire or pulseaudio(-bluetooth) here, and neither should need much configuring for exposing a HFP device, but if you're dead set on "ALSA only" you still need something to implement the BT side of things, Which would mean bluez-alsa from the AUR https://wiki.archlinux.org/title/Bluetooth#ALSA and the documentation for HFP here: https://github.com/arkq/bluez-alsa/wiki … evices#hfp
