In hardware, the audio from the 2A03 APU pins go through an inverted preamp using one of the 74HCU04 inverter chips in the motherboard. Though this may be cost-effective on Nintendo's part, the signals on the hex inverter chip can interfere with one another, especially on the audio. This can be heard as a buzz or a high pitched whine. The only known signals to interfere with the audio so far is: - /A13, the inverted signal of PPU A13 going into the cartridge connector. - /OE1, Output enable for controller reads, though this is only found present on the RF Famicom.
