Re journal: haven't seen that. Since update uptime on my main device is ~40 hours and journal is working fine. So, something is off in your case. Try to check out state of systemd, maybe some service is crashing?

Re USB sound: never checked and cannot comment on it. Did it work earlier on Tama? XA2 version is the same - 3.4.0.24? Try to open a topic on the forum and I will ask for help - Jolla devs will probably prefer to help via official forum. Then you will be able to test their solutions.

USB to analog works for me, that I test.
