How to start Jack Server for Pisound?

In case you don't have qjackctl installed, run:

To start the server, configured to use Pisound, follow these steps:

  1. Run QJackCtl (either from the Applications->Sound & Video menu or executing 'qjackctl' in a terminal.
  2. Click Setup...
  3. Make sure that the following settings are set correctly:
  4. Sample Rate is one of '48000', '96000' or '192000'. (The higher the sample rate, the more there is data to process for software. However, higher sample rate has slightly less latency, if software is fast enough to keep up!)
  5. Input Device and Output Device both are set to 'hw:pisound'.
  6. MIDI Driver is set to 'seq'
  7. Close the Setup window.
  8. Click Start.
  9. If everything is fine, you should see 'Started' text written at the top left corner of the status area.

Note: If something goes wrong, try different settings in Setup, and make sure that the sound card is not being exclusively used by some other software.
