The stock diagram shows muting transistors (Q1, Q2) that short the output to ground during startup. These cause distortion in UPD mode. Remove them and replace with a jumper wire.
Creative no longer hosts the service manual publicly, but verified copies exist in vintage audio archives and GitHub repositories. When you find the file (usually a PDF or high-res PNG), here’s how to read it efficiently:

Located on the right speaker, it controls the input signal levels before amplification.
The (part of the SBS series) is a popular 2.1 speaker system often sought after for repairs due to common issues like dead power transformers or broken Mini-DIN connectors. While a single "official" schematic is rare, the circuit is widely documented through community teardowns and repair guides.
