Intermittent crackling noise occurs while playing songs on YouTube Music

[slowhand]

Intermittent crackling noises occur while playing music on Chromecast (YouTube Music) after a firmware update (WiiM Ultra Firmware v5.2.704152 - Jan 10, 2025).
The noise still occurs even with firmware version v5.2.705437 - Jan 23, 2025

I have observed crackling noises in the following environments.
1. Input : Chromecast (Youtube Music), Output : USB out (DAC : Topping E70 Velvet)
2. Input : Chromecast (Youtube Music), Output : Optical (Integrated amp : Denon PMA-2500NE)

The noise is not observed in the following environments.
1. Input : HDMI, Output : USB out (DAC : Topping E70 Velvet)
2. Input : Chromecast (Youtube Music), Output : Line Out
