Hello everyone!

I’ve used FarPlay with a Mac before and it’s always worked well.

Now I’m using Fedora Workstation 43, and the delay is very high. The delay is always more than 80 milliseconds (more than 100 in the attached picture).
I’ve set the buffer size to the smallest setting, but the changes are small.
Everything is updated as far as the operating system is concerned.
This happens when using the external mic and also when using Komplete Audio interface.

I followed the instructions in the “Getting Started” section. I couldn’t find anything for Linux, so I used the Windows section as a guide.

Is there anything else I need to do?

Dear José,

Thanks for your screenshot. In that Preferences > General Options page, please click the Microphone pull-down menu and choose the listing for your Komplete Audio interface in the ALSA devices sublist. Do the same for the Headphones pull-down menu.

Could you let us know whether the suggestions above reduce the local latency? If the local latency remains high, could you share screenshots of the options in the microphone pull-down menu and the options in the headphones pull-down menu?

Thank you,
David Liao

Hi David

By selecting the Komplete Audio in the ALSA devices, the latency skyrockets to 900, then comes crumbling down to 40, but the sound is terrible, completely distorted.
Please see the video in this link: https://drive.google.com/file/d/1X-4zgcIl9F1Rz91wEY0X8sgdXKfp6FdX/view?usp=drive_link (there is no sound, but you can see what I mean).

I’m sending the screenshots of both pull-down option.

Dear José,

Thanks for the update. Could you try the following? Screenshots below are adapted from QjackCtl’s documentation at Sourceforge.

• Quit FarPlay.
• Open QjackCtl. If the Stop button is red, click the Stop button. Click the Setup button (wrench).
  
• In Setup > Settings > Parameters, set the Driver to alsa, the Realtime option to checked ✓, the Interface to your Komplete Audio interface, the Sample Rate to 48000, the Frames/Period to 32 (you can try 16 for lower latency or 64 for higher stability later), and the Periods/Buffer to 2. Press OK.
  
• In the main QjackCtl window, press the green Play button (to the left of the stop button).
• Open FarPlay. In Preferences > General Options, choose the JACK listings for your Komplete Audio interface for Microphone and Headphones.
• Check whether local latency improved.

Thank you,
David Liao
