alsa-info from 5.19.7

After upgrading the kernel to 5.19.8, my HDMI sound devices have disappeared.  I don't see any .config changes between .7 and .8.

The card is:

 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfcaa0000 irq 75

0d:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 HDMI Audio [1002:ab38]
	Subsystem: Micro-Star International Co., Ltd. [MSI] Navi 10 HDMI Audio [1462:3822]

I'm attaching alsa-info output from 5.19.7.  Will boot back to 5.19.8 and investigate further.

Curious enough, on the second boot it appeared but dmesg is full of "spurious response" errors like:

Can you do a bisect ?

This patch fixed it for me on similar hardware:
