Belkin TB3 Pro Dock issues with Sonoma

[seggy]

The saga of trying to get my '19 iMac back up and running but with an upgrade to Sonoma continues...

When I use the TB3 Pro dock, I have a few problems with it. I know it was (mostly) flawless with Monterey and I've since used the dock with other Macbooks with no issues.

- Front USB-C port is weirdly finicky, C peripherals that will show up when plugged directly into the Mac don't
- Displayport to a 1440p monitor disconnects sometimes (three times so far, and I've had it attached less than three hours)
- Dock audio isn't recognised at all

I've yet to stick more stuff on it that I want to (awaiting accessories) so I'm not sure if this will be the end of it, but the above list is already enough for a crappy experience. Is there a reason / fix?

I’ve been using the OWC dock and it’s been rock solid. It powers the computer and drives my 4K monitor, 4K webcam, gig Ethernet, SSD drive, wireless keyboard/mouse and some card readers.

All no problem. Once in a rare while, it doesn’t seem to detect the monitor when I plug it into the MacBook. Sometimes waiting fixes it and sometimes I unplug it from the MacBook and plug it back in. That’s the worst of it.

First thing to check is always the cables.

It's fine on an Air (on Monterey).
