Mon March 1, 2:30 pm PST JACK clinic, JackTrip meeting, OS X JACK uninstaller

by tersewings

There will be a JackTrip meeting on Mon March 1 at 2:30 pm PST. We'll start by presenting the jitter buffer, a new JackTrip feature. Around 3:30, we'll invite people to present any issues they've had running JACK and ask engineers who are present for advice. If you'd like to volunteer to work on JACK or present any questions or issues, join us here: https://meet.jit.si/jacktrip. An engineer in the JackTrip community has developed a beta uninstaller for JACK on OS X. Feel free to message me if you'd like to use or test it. Bonnie

Mon Feb 8, 2:30 pm PST Meeting on JACK in the JackTrip Community

by tersewings

On Mon Feb 8, 2:30 pm PST, Stéphane Letz will lead a Q & A session on JACK in the JackTrip community. There are developers in our community who are currently looking into tasks such as uninstalling JACK and bringing back Jack Router. Those who are interested in volunteering in documentation, support or coding, as well as those who are leading parallel efforts to revive Jack Router are especially encouraged to attend. Message me privately for the Zoom link. Bonnie

Assistance w/ Win10->Raspberry Pi

by lists＠lizardhill.com

I stumbled across Jack recently, and have been having issues getting it working. I'm looking for a straightforward guide on how to configure Jack as a network receiver on multiple Raspberry Pi's, and Jack as a network sender on Windows.... so I can broadcast from Windows to multiple Pi's over LAN/Wifi. I'm planning on using this for distributing audio to speakers from a live playback and mixing system, so latency is critical. The audio should come from the Windows system playback (a virtual audio cable, or just capturing system audio is fine). It should transport over the LAN/Wifi to the Pi, and then playback through the Pi's built in audio jack/HDMI/HAT DAC. There seem to be various solutions doing this with RTSP or Pulse, but none are low latency, they all have 2-3 seconds of delay. I've got it working fairly well with TuneBlade and Shairport-Sync, but the delay is still in the 1/2 second range. I've tried Max2Play, Volumio, etc... and they all have the same latency issues. This is where Jack seems to be the be the best solution, since it's synchronous. I've seen various articles where others have done this, but I'm unable to recreate their success (most articles are many years old). Can anyone assist? Thanks!
