rock64 Tvheadend problem with Kernel 5.15.y current

[hhill]

I installed tvheadend on Armbian 22.08 Jammy and Bullseye using the 5.15 kernel.  Tvheadend runs fine for a while and then freezes and disconnects filling the log file with the following message:

 

rock64 kernel : au0828: recv_control_msg() Failed receiving control message, error -71.

 

At first I thought it was a problem with Jammy, but I still had the same problem on Bullseye.  So I switched to the legacy kernel 4.4.213-rockchip64  and  I do not have the problem. 

 

I am using a Rock64 Ver. 2 with usb dvb tuner for tvheadend and it is stable running Bullseye with kernel 4.4.213.

 

I am not sure what changed between these kernel versions, but it seems to cause this problem.
