I have the LE model and have had no issues with wired audio. I mostly use Bluetooth though. But I checked for this very issue.

I’m sure they will swap them back for free. It sucks, but it’s really not a big deal.

One thing that seems to be a lot better for me is using moonlight. Not only can I now run it at 90 fps, it does seem much smoother with less dips. Probably from the wifi 6 upgrade.

Where did you sell yours at? I have a 1 TB in mine and having trouble selling it.
