Windows can't connect to hosted jacktrip.org servers or stanford test servers

[vicwomg]

This seems windows-specific: getting this error connecting to jacktrip.org hosted servers:

When connecting to the stanford test servers, seeing this:

Some good info from the jacktrip group:

"This was somewhat instructive, in that it explains why I can hear myself but nobody else can. It's because I'm not actually connected! It looks like JamTrip doesn't detect when the connection fails, but goes ahead and connects the local capture ports to the local playback ports. I include a typical log below.

So I think it would reduce confusion a whole lot if JamTrip detected that the jacktrip process has already exited. Beyond that, I'd love to know why jacktrip isn't succeeding. I find when I run it at the command line, it fails as below with messages about mismatched buffer size/sampling rate in over 90% of my attempts.

This is all talking to servers at jacktrip.org."

Here's a Win 10 installer Chris Chafe made last June for v 1.2:
https://ccrma.stanford.edu/software/jacktrip/windows/jacktripInstaller.exe

If you could let us know whether you still see the problem after switching to this version, it would help us troubleshoot.

Thank you! That worked fine, in at least the simple tests I did.

It's a bit of a weird installer--it creates a folder with a jacktrip stub, unlike v 1.2.1, which comes all bundled into a single executable. That means I couldn't simply drop this jacktrip.exe into the JamTrip resources folder. However, I used an obscure feature of Windows to do something resembling a Unix symlink, and that allows me to run JamTrip with this version as well. Yeah!

cd C:\Users\Bill\AppData\Local\Programs\jamtrip\resources\resources\bin
ren win32 win32-1.2.1
mklink /d win32 C:\apps\jacktrip1.2IsHere
symbolic link created for win32 <<===>> C:\apps\jacktrip1.2IsHere
