"Quick Tips" is a place to share information on how to improve low-latency performance of UbuntuStudio and particularly JACK. Please report the steps you took to achieve your configuration, along with performance metrics: Your sampling rate, buffers/periods setting, and an estimate frequency of XRUNS. -- e.g. Added line "module foo" to /etc/foo/foo.conf and entered "/etc/init.d/foo restart" to reload foo. Achieved six hours of performance at 96kHz/3/128 with XRUNS only happening when starting applications. -- Setting and controling JACK is easy using '''JACK Control''' (''qjackctl''). For running JACK with ''Real-time Full-Duplex'' capabilities using Audio Card ''Intel Corporation (ICH6 Family) High Definition Audio Controller'', with ''ALSA ALC880 Analog Playback/Capture'', set JACK preferences on Setup.../Settings tab (''qjackctl'') to: * check Realtime, with prioity: 0 * check Force 16-bit * Frames/Period: 128 (lower this for reduce latency) * Sample Rate: 44100 * Periods/Buffer: 3 * Audio: Duplex (default) * Driver: alsa (default) * and leave the others to default. Using ''linux-lowlatency'' package is recommended for better performance. This setting will achieve, 44.1kHz/3/128. The number of XRUNS was not counted.
