@waldi@steph@mia@ShadowJonathan I know but it's really not the same kind of deal. Like unlike with a laptop where few adapters can be fine (though we've probably all seen Apple users getting frustrated by needing those), with a smartphone it's really annoying to carry with you.
And I guess having to also carry a Y cable so you can charge + listen to music at the same time.
@waldi@lanodan@steph@mia@ShadowJonathan That really depends on the flavour of passive or active audio throughput and the phone manufacturer. I've got a blackview phone with passive audio output (DAC on phone) that works well with their own headphones but the passive adaptors I've tried failed (there's no agreed standard). If I use an active adaptor the signal to noise ratio at low volumes is terrible and the USB output gets shut off after 15 minutes bacause the phone thinks it's inactive.
@waldi@Doomed_Daniel@Nibor4000@steph@mia@ShadowJonathan Oh wow that reminds me of how iPod shuffle and some other smol devices would have an audio jack that could also work as USB. (Or some smartphones where the headphone jack can also go in UART mode)
@Doomed_Daniel They do, or did in the past. See "Analog Audio Adapter Accessory" (Appendix A of the USB Type-C spec before revision 2.3). They connect the raw analog lines through D+ and D- (and some sensing stuff on CC, VConn or so).
But it got removed, so on newer devices this might not longer work.
