Unexpected Xubuntu updates have broken my USB DAC for music playing. The DAC works with one computer having (uname -r) kernel 6.5.0-28_generic. I have two others with kernel 6.5.0-35 which report in dmesg:

All 3 computers have (lsb_release -a) Ubuntu 23.10 Mantic, but that is not true because they have been updated at different times.
