I have a Pi 3 B+ and overall it's really good but has one glaring defect: the audio from the audio jack with a set of (non-HDMI) external speakers is total and utter garbage, distorted almost beyond recognition. (I found a few software fixes but none were effective.) Would this inexpensive USB converter from Adafruit be adequate to solve my problem?

...or do I need something more complex and expensive?
