Does WD19TB dock exist, only see WD19TBS

@DylanMitchell  I forgot to add that if you need audio input and can’t get a non-S dock, you could get a simple USB audio interface like this instead. Plugable has a solid reputation for quality products and knowledgeable tech support personnel when needed.

Thanks, I did read in the guide that WD19 docks won't fully power some laptops and you still have to use the cord or on newer models two USB ports. The number of USB C ports is very limited you lose the USB C on the laptop to charging and have at most two USB C ports on the dock. 

3.5 mm jack would be very handy for speakers you want to leave plugged in all the time. Most new speakers do have Bluetooth but 3.5 mm can have better audio quality and speakers can keep trying to jump to other Bluetooth devices like a phone.

Parts are hard to get, nice Dell has an option available rather than just waiting around. WD19 docs aren't great I miss the old ones but work better with Dell than most of the other docs. I'm not a huge fan of USB C and USB C charging. Better speeds and more convenient but USB C connectors can bend easily and I prefer a good old power cord. At least many new laptops have 2 or more USB C ports, just wish they kept the old charging port, improved the docks, and stopped frying batteries. Swollen batteries are common with new docs and new chargers. 

@DylanMitchell  I agree with much of that.  I've found it frustrating that so many laptops seem to provide either only one USB-C/TB3 port or provide ONLY some USB-C ports and no "legacy" ports.  I want more than one modern port, but I also don't want to have to use dongles for every legacy device I might to use.  It's one of the reasons I switched to another vendor when I bought my latest personal laptop in late 2019.  I was replacing an old XPS 15, but the current XPS 15 at the time (the 7590) only had one USB-C/TB3 port, which I didn't consider acceptable in late 2019, and now their replacement XPS 15 (the 9500) switched to having only USB-C ports.

I use the 3.5mm jack for speakers myself, but if I needed a Dell dock asap, I'd just buy that USB audio interface adapter I mentioned.

As for dock design, I think USB-C/TB3 is overall a step forward, though I've definitely seen cable durability reported as an issue.  But on the plus side, the cable means you can now have your dock at the rear edge of your desk and keep your laptop closer to you rather than the previous design where you had to drag your dock around with your laptop.  And having an industry standard design means it's now possible to use Dell docks with non-Dell systems and non-Dell docks with Dell systems.  That has come in handy for me and my wife at home.  We each have Dell and Lenovo laptops.  She has a Dell dock, and I have a Lenovo dock.  All of our systems work with both docks.

I found this whilst researching differences between the WD19TB and WD19TBS (because quite a few 19TBs are now available on the used market at low prices).

In the end I personally confirmed (by opening a TBS up) that the WD19TBS has a space for the 3.5mm jack on the circuit board, but it's not populated.  From this I conclude that both models are near identical, except that the jack and sound chip have been deleted from the TBS model.

I don't know why they revised it, but I guess that it's one of the following reasons:

• The revision was made during the global chip shortage - possibly the sound chip was just unavailable.
• The 3.5mm jack didn't work with Apple Macs (no driver for the sound chip I assume?), and they deleted the jack to avoid warranty claims and support calls etc. by Apple users.
