I see a lot of people complaining that the Fairphone 6 doesn’t have an Aux jack.

Just use an adapter cable.

A 3.5mm Aux jack takes up a significant amount of space just to connect a few wires that could be connected through USB-C anyway, that space could be used for a bigger battery.

Even if there was a good enough reason to keep Aux it should be 2.5mm Aux and not the usual 3.5 as it does exactly the same thing but uses less space

    I also did some searching again and came across the usb-c alternate modes. There is an alternate mode for “Audio Adapter Accessory Mode” and this needs certain architecture of the adapter you are connecting to be automatically detected.

    From the spec: "The analog audio adapter shall identify itself by presenting a resistance to GND of ≤ Ra on both A5 (CC) and B5 (VCONN) of the USB Type-C plug. If pins A5 and B5 are shorted together, the effective resistance to GND shall be less than Ra/2.

    A DFP that supports analog audio adapters shall detect the presence of an analog audio adapter by detecting a resistance to GND of less than Ra on both A5 (CC) and B5 (VCONN)."

    So the host has to support it, and the adapter needs to be manufactured so that it turns this feature on.

    But i find it difficult to find firstly if my phone supports it, and if the jack is designed with it in mind.

    And after that we apply the complexity of also charging in this mode, and chespest possible manufacturing of these things, or they just throw their own DAC in the adapter and call it a day so from phones dac -> usb-c alternate audio mode -> adapters dac -> headphones.

    And nowhere have i ever seen the manufacturer of these dongles say how its constructed.

    But i will stop here and forget about this because it is way outta my league.

    I also have absolutely no idea about if anything i say is correct so readers beware feel free to correct me on all thing usbc!
