| Driver setting issues | Disable front panel detection | 85% |
4. Expert advice and precautions
1. Anti-interference tips: Avoid arranging audio cables and power cables in parallel. Cross routing is recommended.
2. Wire selection: According to the 2023 Audio Association test, oxygen-free copper wire core loss is 27% lower than ordinary copper wire.
3. Interface maintenance: Complete plugging and unplugging at least once a month can prevent oxidation (more frequent in particularly humid areas)
4. Safety warning: Be sure to ensure good grounding before connecting professional equipment to prevent static electricity from damaging the circuit.
5. Observation of future trends
According to recent industry trends, the usage of USB-C audio interfaces has increased by 210% year-on-year, but the traditional 3.5mm interface still accounts for 72% of the market share. It is recommended that users choose composite wires with transfer functions to meet the needs of the transition period.
