It’s much better on ARM. And their external monitor support is so much faster and reliable now. Having control over all their hardware has made a noticeable improvement.

This is not my experience. My M1 Pro MacBook has very strange issues with sound over HDMI. I usually need to reboot it when I connect it to my TV or media won't play if the sound is output over HDMI.

Same here on an M1. If you find a solution…

Every time I turn on my M1 Max Mac I have to unplug and replug the HDMI but other than that the machine is a dream to use.

That's annoying but could also be caused by the monitor or TV HDMI implementation.

I don't think so. In that state, video will jump and stutter wildly, run very fast, and audio will be very broken. It's not just the sound that's affected.

Which all could be caused by a broken HDMI implementation (refresh, synchronization and audio are all encoded and synchronized). But of course I could be wrong and every M1 Mac has severe issues connecting to HDMI TV's.

Or it could be the cable.

For me, I have an M2 and no issues. Was worried about v1 issues (same for VisionPro—will wait until v2)

Tried a bunch of cables, including expensive ones. The only thing that solves this is rebooting the laptop.

I've tried a recent LG OLED, and a bunch of other TVs at friends and it happens every time if the laptop has been sleeping previously. If it's a fresh boot it never happens. That leads me to believe it's something on the laptop side.
