So I had a similar issue with the same machine a couple of days ago. I was in a Zoom call and the other person's voice started sounding tinny and robotic. I was using the 6.4.8 kernel at the time, but this time I wasn't using HDMI audio, just the laptop's speakers. In this case, I just rebooted into the 6.1 kernel and carried on my call and unfortunately didn't have a chance to grab my dmesg log or anything.
