Line 38: − Anyway, when you configure the bluetooth device and get it working with Zynthian, i suspect that latency will be too big for playing/sequencing in real-time. A wireless device like this normally need a big buffer to avoid “cuts”. In my very first tests I used a BT speaker “just for fun”.

A “Bluetooth speaker” is an audio device in its own. In order to get this device working with Zynthian you need to configure it with Jack Audio. See the “audio config” tab in the webconf tool.

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.
