USB audio cuts out randomly on Librem 5
I'm not sure where else to put this issue, there doesn't seem to be a general repository for posting 'PureOS issues', and it's possible this might be a hardware issue. Apologies if this is in the wrong place, I'm happy to repost elsewhere.
When my L5 is actively using a USB audio device (Tested with Lollypop and Gnome Podcasts), audio will periodically cut out and move to the internal speaker. This happens with multiple unrelated USB audio devices (a Kensington phone dock, a Jabra headset's 2.4 GHz dongle, and a cheap USB-A audio in/out plug).
Each time the audio cuts out, dmesg
shows connection events for all of my USB devices, as if I had just plugged them in. I note that it does not show any disconnect messages, just connects. It does not seem to have anything else helpful (just a warning about the touch screen turning on.
This problem seems to be limited to USB audio. The internal speakers, and external bluetooth devices work correctly.
