The only difference between direct out (set to post preamp) and using Input sockets for record is the Surface Trim. If the trim is set to 0 there should be no difference.

The issue with using direct outs in the explained manner when you punch the recorded channels back through the GLD for a virtual sound check is that the surface trim is potentially applied twice to the signal.

This may not apply if not using the surface trim at all, but using the sockets for recording in this manner is more correct for virtual sound check. As the audio is coming from for recording and returning to for playback to the exact same position in the signal chain.

I use a very large dante system for live use (6 or more devices with 70+ channels and multiple hops per signal path) and there is no lack of documentation available. If you read the Audinate documentation thoroughly as well as the documentation for the devices it is clear and easy.

But if you are trying to run 2 clocks on one system (where point 1 is valid) by telling the dante card to be the master of the dante network (or to be slaved from the network) and the GLD to master the dante card you will cause pops and crackles. But this has been a consideration since the beginnings of combining digital audio devices together.
If you want to use the GLD as master, you can change the option in the dante controller to slave the dante card to the GLD (‘Enable Sync To External’). Either this or slaving the GLD to the dante card as suggested in this thread solves the issue of having 2 clocks trying to get along.

Furthermore, the Allen Heath manual for the M-DANTE suggests to set it up in this manner, from the manual:

Dante cards Use Dante Controller to tick ‘Preferred master’ and ‘Slave
to external wordclock’ for the Master MixRack/console card only.

For some reason you have copied only a portion of this sentence from the manual and turned it on its head, saying the console should be slaved to the Dante card, however the sentence is suggesting the card (and hence the dante network) should be salved to the console. Either way though will work. The manual is not an ILive manual, but the manual for the M-Dante card and it encompasses the I-LIVE, GLD and MEU.

For point 3, the virtual soundcard will show the green speaker in the receive tab of its device view when receiving above -61dbFS, as stated in the manual. There has been an issue with macbooks and the use of thunderbolt ethernet adapters that has been resolved, this may have prevented this from working, as stated in the dante controller change log.

All documentation always suggest keeping firmware and software up to date.

Signal will still pass despite version differences with Dante, there has never been a version incompatibility that will stop audio. Wrong versions in the past would only limit information in the device view window and newly added features, however you can still subscribe to channels. It is more likely there was a setting incorrect to prevent signal from passing.

I think the statement that there is a lack of documentation is unfair, nor is it hard to find, as it comes with the M-Dante card, and with the Dante controller/virtual sound card.

Nothing suggested here is unavailable in the manuals. Even the fact that the ‘input socket’ are the preamp output is clear when you hit the help (?) on the i/o page of the GLD.

Its unfair to manufacturers to claim there is a lack of documentation, when its more clearly a lack of thorough reading.
