USB audio interface - how to setup correctly?

Patchbox OS
1

Hi there,

i am trying to use my tascam dr40x as a sound card with patchbox os.

I installed the patchbox os ( [Beta] Patchbox OS image 2020-11-23) on my rpi4.

Connected the usb audio interface and chose the following settings in the jack config:

default soundcard - USB
samplerate - 48khz (this is also setup for the dr40x)
buffer size - 128
period - 2

The audio interface is connected and powered via the USB port of the rpi4.

When I test run in supercollider on the rpi4 I can hear something but very distorted.
Any hint?

Thanks in advance,
best regards,
Sebastian

… or has anyone a working audio interface together with patchbox and rpi?

Could you share the model, your settings and how you power it?

Thanks in advance,
Sebastian

Try using 512 or 1024 buffer size for USB audio cards.
