Audio issue (crackling noise) using PS5 with USB 1.1 DAC/AMP

Understanding Audio Glitches When Using PS5 with a USB 1.1 DAC/AMP: Troubleshooting Crackling Noises

Introduction

Connecting gaming consoles to high-quality audio equipment can significantly enhance the gaming experience. However, compatibility and connectivity issues may sometimes lead to audio disturbances such as crackling noises. This article explores common issues encountered when using a PlayStation 5 (PS5) with a USB 1.1 Digital-to-Analog Converter/Amplifier (DAC/AMP), specifically focusing on troubleshooting crackling sounds during gameplay.

Scenario Overview

A user reports experiencing intermittent crackling noises originating from their audio setup when connecting their PS5 to a Cambridge CXA81 stereo amplifier—an integrated amplifier with a built-in DAC—via a USB cable. The DAC is configured in USB 1.1 mode, primarily intended for compatibility with older devices, including the PS5.

Key Details:

Audio Setup: Cambridge CXA81 stereo amplifier with embedded DAC
Connection Method: USB cable (configured in USB 1.1 mode)
Issue: Random short-duration crackling noises in one channel (either left or right), occurring approximately once per minute across various games
Additional Observations:
PS5 recognizes the DAC as headphones, restricting the ability to switch to speaker mode
No issues observed on PC using both USB 2.0 and 1.1 modes

Troubleshooting Steps Tried

The user has performed several standard troubleshooting procedures:

Disabled 3D audio in PS5 settings
Lowered volume levels both in games and system-wide
Tested different USB ports and cables

Despite these efforts, the crackling noise persists, indicating that the issue may stem from compatibility or signal integrity rather than simple configuration errors.

Potential Causes and Recommendations

USB Mode Compatibility and Power Management

The PS5’s recognition of the DAC as headphones and the operation in USB 1.1 mode might introduce compatibility issues. USB 1.1 has limited bandwidth and power delivery compared to USB 2.0, which could cause intermittent audio glitches.

Recommendation: Attempt to switch the DAC to USB 2.0 mode (if possible) and verify if the crackling persists. Although 2.0 mode may require drivers on Windows, the PS5’s support differs, and testing this mode could improve stability.
