The audio didn’t come through the PSU. I also experimented with repositioning the cables, but it didn’t help. I inspected all the cables and confirmed they weren’t affected by hair or dust. Everything seemed normal. I’m fairly certain the issue lies with the motherboard. It’s unclear, but the sound appears in the higher frequency range, around 16000–18000 Hz.
