HDMI sound drops outs after recent Slackware64-current upgrade.

I normally use Slackware64-current for my computers for that bleeding-edge thrill. I recently installed S64-current on my Dell 7920 (dual Xeon 4114s) with an Intel ARC A770 GPU hooked up via HDMI to a 4K Hisense A6H. It was installed April 3rd. The system was running perfect, so I upgraded it on May 10th to the latest S64-current. Unfortunately, that broke some stuff... normally, I am pretty good at fixing any problems. In fact, since the 6.6.30 kernel broke gaming, I immediately regressed to 6.6.29 to fix that.
However, the upgrade also seems to have broken the sound over HDMI. Basically, the sound is cutting out... I only get about 10%-40% of the sound coming out the TV I am using as a monitor. I regressed back to the 6.6.24 kernel* packages that were originally working. Looking at the other packages that were upgraded in S64-current between Apr 3rd and May 10th, nothing else seems sound related, except pipewire (1.0.4->1.0.6) and wireplumber (0.5.1->0.5.2), but I'm still using pulseaudio.
Sound going out the 7920's motherboard's sound card is fine. I also have a laptop (Thinkpad P71 with a NVidia GPU), also running S64-current (May 10th)... also displaying on the same Hisense A6H via HDMI... that sound is fine.
While trying to figure out the problem, I inadvertently booted my Dell 7920 into Window 10 Pro... and surprisingly, the sound is also dropping out there over HDMI as well.
I immediately thought it must be a hardware problem... so I swapped out the ports, the HDMI cable and triple checked my settings. It just seems so strange that I would suddenly have a hardware problem right as I reboot for my upgraded Slackware.
I AM STUMPED. Bear with me, since I acknowledge that this sounds like a hardware issue, but I am posting here because I'm curious if there was any package that got upgraded between Apr 3rd and May 10th that would affect the sound using the A770's HDMI for sound.
I am open to any other suggestions.
