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 Compl= eted 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. --=20 You may reply to this email to add a comment.
