Raw logs and full analysis

The full analysis is in the attached report-kernel-bugzilla.md; raw log
excerpts are in
report-bt-ax210-logs.tar.gz. In short:

Intel AX210 (USB 8087:0032) stops reporting HCI event 0x13 (Number Of Completed
Packets)
for the A2DP headset's ACL handle while the ACL link stays up. Audio goes
silent, BlueZ
still reports the device as connected, L2CAP echo keeps working, and only a
disconnect/reconnect restores playback. Happens 1-3 times per day, during
playback and
while the sink is idle, with SBC at short range. No USB errors and no kernel
warnings.
