        Hmm, probably a Linux kernel driver issue? Does the usb soundcard work with Desktop Linux?

        Fairphone 5 (waiting for port)

          Do you have a pine phone? It has a modern kernel. I'm curious how far we'll be able to get with it with respect to external hardware.

            @KrishneshG Please tell us which device. With an Android-based phone things are already supercomplicated regarding the audio routing so it will be hard getting this done. On top the USB port configuration is a separate topic and as far as I know we only support adb and mtp protocol and I am not sure what happens if you connect usb slave devices to that port.

              @poVoq Plugging USB-C earphones into a computer, will reroute automatically.

              I dont think this is an Ubuntu Touch core issue, but a Ubuntu Touch porting issue, so it'll be from device to device, I'd assume?

                @Flohack USB OTG works fine, as long as the drivers are there for the thing you're plugging in. USB pro audio drivers are probably not built by Android kernels and so this won't work.

                  @dobey this is correct my current device is a one plus 3 to monitor the progress of ubports before I decide to go all in on a all Linux device. If my hardware is the limit that's fair.

                    @KrishneshG Does your USB DAC work on the device with Android running on it?

                        @PhoenixLandPirat No. Headphones and a DAC are not the same thing. And the question wasn't for you, it's about a gadget the OP owns.

                          @dobey "The OnePlus Type C Bullets headphones will include a high-end, professional DAC by Ciruss Logic and come with a higher dynamic range, higher signal-to-noise ratio, and low noise floor than the predecessor", I'd feel bad not answering a question that I know the answer to, because it's not asked directly to me, sometimes, its good to help even when you're not asked to. πŸ™‚

                            @PhoenixLandPirat That is a specific set of headphones. Just because they also have a DAC included, does not mean the OP is asking about that.

                            How about we clarify from the OP exactly what they are asking about first, hmm?

                              @PhoenixLandPirat Its all about how the device identifies itself on the USB bus. If it identifies as headphones it doe snot matter how it is internally working. If it identifies itself as soundcard for example thats another story.
