Purchased a Waveshare USB to Audio device...

It worked without any issues 🙂

Additionally, just letting you know, Waveshare device fits perfectly to my cabinet setup since it can drive the speakers directly and the audio quality is clean and loud.

Reminder, do not connect the output of that device directly to SCART or head-phone jacks since its amplifier chip is, by default, configured in "bridge-tied load" mode. Which mean its output level is too high for devices accepting line-in level audio.

So anyone looking for an "line-out" level USB audio, that device is not the right thing for you (unless you open it up and hack the PCB to change the operation mode of the APA2068KAI-TRG chip to SE (single-end) and accomodate a line-out jack.
