Do you have any updates on this issue? I think, i have the same or a similar issue. I have a Thinkpad X1 6th Gen. upgraded with a Intel AX200NGW Wireless Adapter and after about 20-40 minutes the audio stops playing while the speakers appear to be still connected. Trying to dis- and reconnect them renders the complete system unusable, i.e. requiring a hard reset to poweroff. This only started happening after i switched to original Intel 8265 card with the Intel AX200 one. Inital connection Apr 27 23:39:12 x1 systemd[1354]: Started Sound Service.

I can confirm that disabling the wifi removes those errors and stops my machine from crashing. |
