Physical Durability: The most frequent "fail point" is the thin C-to-C cable. For a DIY project or product, replacing this with a high-purity copper or silver-plated cable is a recommended modification to prevent core breakage. The Conexant is a popular, high-performance USB-C DAC

to understand its Class G architecture and power constraints. Pin 5 is actually HP_DET, not GPIO2 (verified

• Pin 5 is actually HP_DET, not GPIO2 (verified by removing R7 → headphone mute).
• USB suspend current is 2 mA (not 0.5 mA as stated).
• Minimum VBUS rise time must be <10 ms, else chip locks up – add soft-start circuit.
• I²S slave mode requires MCLK even if datasheet says “optional”.

Alternative: Keep a "silence" track playing in the background or use an app that keeps the USB bus active. 3. Troubleshooting Connection Issues
