@kugiigi I have a Google Pixel 3a.

Ok, I'll try to set up SSH, and then report back.

In any case, switching audio sinks doesn't appear to be a fully supported feature at this time, correct? Can I place it on a "feature-wishlish", if there is such a thing? I'm probably not the only one

@kugiigi said in USB audio devices don't provide any output:

pactl load-module module-udev-detect

Ok, I tried that, and got the following error message:

phablet@ubuntu-phablet:~$ sudo pactl load-module module-udev-detect
[sudo] password for phablet: 
Connection failure: Connection refused
pa_context_connect() failed: Connection refused

Hi everyone,

I'm new here, and to UT, but so far, I quite like it. I hope UT will continue to improve.

Anyway, I have a Pixel 3a with UT 20.04 on it, and I tried connecting a Samsung USB-C headset to it - did not work. Same thing with a different USB audio adapter (IcyBox IB-AC527, connected through a USB-C to USB-A adapter).

The devices are recognised by the OS (listed in lsusb), but no audio is played through them. They work fine on my main smartphone (Samsung S24) as well as my Linux x64 laptop (running Xubuntu 24.04). Audio continues to be played through the phone speaker, as if the USB audio adapters weren't even there.

lsusb output (for the Samsung USB-C headset):

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 04e8:a051 Samsung Electronics Co., Ltd USBC Headset
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Is there anything I can do to route audio to the headset? Or is this feature simply not supported yet?
Thanks!
Ben
