Configuring Audio Devices (view source)

However, if you configure the bluetooth device and get it working with Zynthian, I suspect that the latency will be too long for playing/sequencing in real-time. A wireless device like this normally needs a big buffer to avoid “cuts”. In my very first tests I used a BT speaker “just for fun”. Latency was a little less than 1 second, more than enough to make it completley unplayable.

===Using Raspberry Built-in audio 3.5mm jack===
The R-Pi built-in audio has previously been reported to have very poor audio quality.
Available in latest rpi-update firmware (Oct 2017) is a new PWM audio driver that significantly increases the audio quality available from the 3.5mm TRRS jack.
To enable the advanced audio driver, add '''audio_pwm_mode=2''' to '''/boot/config.txt''' and reboot.
