I can get it to work if i unplug the Mac from the docking station. Once replugged no issues till next time the computer switches off the displays. The computer is able to access external disk drives when woken up before i disconnect/reconnect. Removing the ethernet did not help (likely not surprisingly) with the displays. I am on Monterey 12.0.1 on a M1 Mackbook pro with Dell D6000

I noticed that I was on DisplayLink version 1.4. With version 1.5 I can replicate the same problem as mentioned in previous posts: with no Ethernet cable i get the docking station and Mac behave correctly.

i'm noticing an additional issue, even with the ethernet cable removed.
the selected sound source is not respected. eg when plugging the dock back in and selecting it as sound source, i have to restart applications which produce audio output (browser/spotify, etc) in order for my sound to be played over the dock.

Can you elaborate please im trying to reproduce this

So basically you select "Dell USB Audio " and then you restart your browser?

## it does not work for me I think

Edit: It does work

to reproduce
1) play sound over dock
2) unplug the dock
3) take your mac for a walk, play sound, do whatever
4) replug the dock
5) sound source switches back to the dock (automatically)
6) play sound -> NO SOUND
7) restart application that plays sound (eg spotify, browser, teams, mail, etc)
8) back to normal

at step 6 you can switch output to mac speakers and the sound is playing, switch back to the dock => still no sound

Also having the exact same sound issues. I hadn't tried closing/reopening the app, I had just completely reverted to rebooting. Glad to know there's an easier workaround!

So I have never used the ethernet port on my docking station and was having these same issues listed here (display is an ASUS). I unplugged power to the docking station and everything came back; monitor detection, sound, external HDD.

Hope this helps.

Removing the ethernet cable from my dock fixed my issue of multiple displays not working on wake. I too had to remove USB-C cable and reinsert every time the machine was woken from sleep. Removing the ethernet cable has fixed this issue.

Macbook Pro Monterey 12.0.1 (21A559)
DisplayLink Manager 1.3.0 (Build 56.111)

What dock are you using? I have an issue with this with my Dell D6000 - I previously upgraded the firmware to overcome this issue, but it has come back with the 1.6 beta. I powercycle the dock to get the screen to come back on.

MacOS 12.1 seems to fix the screen not waking from sleep with the D6000 (latest firmware) and the 1.6 beta.

I can confirm the above as well. Monterey 12.1 seems to fix the issue.
