It seems to be non-obvious how the ASIO SDK and its license integrates with Jamulus. We should do everything to make the situation more clear.

• Add a clause on the Windows ASIO client download page saying "Please note that you are not permitted to redistribute this binary without acquiring a licence agreement from Steinberg" (and in the About box)
• Make a Windows server download using "nosound" which doesn't touch ASIO SDK
• Verify that JACK Windows builds don't touch ASIO SDK Improve build logic for JACK-related builds & warn about ASIO #2443
• Check/update ASIO mentions regarding license requirements in
  • Installer Startup/Splash-screen ("ASIO" + copyrights notice - see 3.b in their Terms, logo is optional)
  • About dialog ("ASIO" + copyrights notice)
  • README.md (copyrights notice only)
  • Website ("ASIO" + copyrights notice, logo is optional).
• Sign the agreement and send it to Steinberg to cover jamulus.io's distribution of ASIO-enabled Windows binaries (we can't cover other usages, sadly) will be done post-3.9.0 as part of Sign Steinberg agreement #2687
  • Who from the team would be available to do that? @gilgongo + @pljones for deeper technical stuff
• Agree approach re. system GPL library exception vs additional terms notice
• Document that users who self-compile and distribute the result should check this for themselves (README.md as well?)
• Add pointers to the code to be careful about this topic, i.e. "never copy from ASIO SDK as it makes the situation more complicated"
  • windows/deploy_windows.ps1 Improve build logic for JACK-related builds & warn about ASIO #2443
  • windows/sound.h Improve build logic for JACK-related builds & warn about ASIO #2443

I'm currently don't plan to work on this myself, but I do think that we should move this forward for the next release and have added it to 3.9.0 therefore.
