2. At some point, the plugin starts detecting the serials for EVERY unit as 65535 (both in terms of what is displayed in the gui and in the directory structure). This is obviously a bug since (a) I don't own a unit with that serial and (b) this is the square of 256 -- I'm guessing it's the highest value that variable can contain and is the result of some failure in the plugin logic)

I had the identical issue with 2x 2x4HD and 2x Wi-DG. One of the Wi-DG is defective. I purchased another one from Deer Creek and thus far almost no issues. For some reason the Wi-DG corrupts the 2x4HD, wiping out the configuration.

I sent the defective Wi-DG back to miniDSP Hong Kong and they email saying I only included one. DO NOT BUY DIRECT FROM miniDSP. In the US, Deer Creek Audio is head and shoulders better.

It's a PITA switching USP cables, but they are the most reliable solution. For best longevity, I have 2 long A-B USB cables from the 2x4HD to my laptop and use 1 foot A-A extension from the laptop to reduce the number of USB connection cycles on the 2x4HD and laptop.

Compared to the network reliability of my TVs, phones, laptops, Fire sticks, etc. miniDSP products are circa 1985.
Functionally, they are the bees knees and no other solution is as simple.

> Pretty please, @devteam, respond with the serial restore process. I've already reached out to support but apparently it takes a long time to respond with a link or a document...

Contents of preferences.xml
<preferences>
  <write_sn_tool value="1"/>
  <auto_check_sn value="1"/>
  <sn value="0"/>
</preferences>

Hold Reset Switch while applying power for about 5 seconds

To update serial number:
    Exit miniDSP app
    COPY preferences.xml into user folder
    remove old serial number folder
    Start miniDSP app & Connect via USB
    set serial number
    Cancel to Config
    RESTORE Factory Default
    Reload configs
    REMOVE preferences.xml from user folder
    remove 65535 folder
    
The Wi-DG is defective. Don't use it.

I had a 10x10HD for 4 years (changed to a nanoDIGI about a year ago).  I was able to vary the volume either by using the knob on the front - or by using my remote; it worked fine.

Also, are you aware you can improve SQ by changing to the 2x10 plug-in ... which runs at 96kHz?

Did you monitor the levels in the plug-in?
I can vary the level, just not accurately.

The v2 remote is less prone to get the 2x 2x4HD out of sync wrt level. One click can still be between 0 and ±1.5dB.
In over 30 years of IR controlled devices, miniDSP products are the ONLY ones with inconsistent level steps. Heck, my clicker TV remote 40 years ago was more accurate!

are you aware you can improve SQ...

I r enginerr. I RTFM before I buy.
Regardless of plug-in the 4x10 is somewhat masked. The 2x4HD SQ is miles ahead

I have now 3 times written and accidentally lost a post longer than anyone wants to read on this. In summary, 

1. The plugin problem is really odd. The functionality to fix this already exists in the software -- you just check if the serial is in a bad state then throw up a modal dialogue prompting the user to re-enter it from the chassis if it is. This isn't a perfect fix but is user experience 10x better than having someone's hd fail over and over again and having to call support and hoping someone notices the corrupt serial. 

2. I suspect that the WiDg isn't so much defective as a very strange design. I have four connected to four 2x4HDs and this happens with all of them. TCPIP doesn't really allow you to end up with someone else's packets unless your ip address changes to theirs, so baring some catastrophically poor design decision (only thing I can think of is some kind of dependency on a broadcast protocol), I'm struggling to understand how having more than one on a network can result in the serials getting nuked (I asked support for clarification and they never responded)

The even stranger part is that I can't figure out why anyone would want just one of WiDgs. There are an overwhelming number of ways to access USB devices across a network, ranging from hacks to software to hardware. If someone needs a whole wireless bridge to manage a single usb device...it doesn't feel like that person is ready to manage the complex options that the minidsp exposes.

3. The history of computer science is pretty much the history of solving state problems. There are a lot of ways to improve on a fire and forget approach even given the limitations of hardware you've already shipped. All these gyrations with the config state being fragile feel to me like one of two things -- either the business feels this is not worth fixing (and doesn't want Devs using resources to do so) or the plugin code is so intensely hard to build and release that it's not a normal cost-benefit analysis (I've seen this happen to a number of companies)

That said, unless someone from the dev team or the business opts to chime in, we'll just have to keep guessing.

The Wi-DG are possibly corrupted or defective.

The response that I got from miniDSP Hong Kong is that the firmware became corrupted:

The test report just came back today and apparently, the firmware on the WI-DG was corrupted when you shipped it to us.

However, our engineers suspect that something might have gone wrong when you were first trying to set up the WI-DG in a dual units setup. We actually stated this as a limitation for the WI-DG in the user manual and using more than one unit is not recommended at this moment.

Which is why I did not purchase Wi-DG when I bought the 2x4HD

Two years later, the Wi-DG page  Using Android / IoS app to control your miniDSP

Linking units For customers wanting to remotely control multiple devices (e.g. control of multiple PWR-ICE/nanoAVR units or multiple USB processors), you can link them up to apply a change (E.g. master volume) on multiple units at once. In the event you're trying to control multiple USB processors (E.g. 2x4HD), you will require one WI-DG per miniDSP USB device. Here are the steps to enable linking from miniDSP's Controller.

It took 90 days to resolve and as yet I do not yet have back my Wi-DG. 

My original Wi-DG SN 180-2265 & 180-2220.
Third W-DG SN 180-1920 which thus far has no issues.

As of late, I have not been doing any configuration using the Wi-DG other than checking and setting plugin levels.

Under an abundance of caution, if using the Wi-DG to configure units, I exit the plugin and restart it prior to connecting the plugin to the Wi-DG.

Apologies, I should have been clearer. I understand that's what they told you. I'm just having trouble understanding how any of that is a sensible response. But I understand now (they said your firmware was corrupt).

Tbh the whole thing feels like a smokescreen. There's a known problem here. Lots of people can reproduce it. They've slapped a "not supported" label on it because they don't want to take the time to fix it. ACTUALLY, I understand that part. I've worked in software for a long time. It's something you have to do in some cases to survive. 

But I just wish we could get some transparency about what is going on. I'm extremely capable in this area, with an extensive background in network engineering, programming and low-level protocols. Chances are good I could engineer a network-level workaround if I understood what was going on. EVEN if there are some really unfortunate broadcast logic problems, I could fix that with old school network broadcast domain boundaries or l3-7 filtering. 

Problem is, without the code, I'll probably never been able to figure out what is going on (or at least it would take so much effort as to make it pretty unlikely). I just wish they'd be transparent about the root cause. I'm not asking them to fix it, just to tell me what is actually happening, because no combination of what support has said squares with the way network and embedded tech normally works.../

Edit: Didn't think of this before, but assuming it is some kind of broadcast confusion, putting them each in their own vlan might just fix it. I don't have any fancy switches at home anymore but I'll see if my router will let me rerejigger the lan side vlan tagging. But then I'm all the way back to "how the heck was this not fixed a long time ago..."
