When the PWM function is activated, there’s a jump in output voltage which results in the popping sound. Until there’s a driver modification, the work-around suggested (other than using the HDMI sound output or an external USB sound card) is to run PulseAudio on top of ALSA and keep the driver active even when no sound is being output.

There are three solutions for this: Solution 1. Make sure your Pi is getting enough power. This is the most common problem with Raspberry Pi's, because they don't come with a standardized power supply. Just make sure you are using a thick and shortcord, and not a thin and long one like phone charging cords. Solution 2.

Step 1. Before continuing, make sure your Raspberry Pi is switched off and then connect the USB audio device to its USB port. Remember, if you need access to both USB ports then use the USB audio device in conjunction with a USB extension cable, preventing the second port from being blocked.
The Dreaded Audio popping issue : raspberry_pi

The Raspberry Pi does not have a real sound card. Its basic PWM thingy can generate some analog noises, but I would not use it for anything serious. Adding a sound card should make everything "sound related" work better. A $5-$10 USB sound card can make a HUGE difference. level 2 Mahoubaka 1 point · 5 years ago hmm i see.

The Raspberry Pi should detect the USB Sound Card and load the kernel module (device driver) automatically. However, this is not guaranteed. So I need to check. Open terminal: sudo tail -f /var/log/messages. Refer to screenshot. The lines are irrelevent because I have not connected the USB Sound Card to Raspberry Pi yet.

An Apple Macbook or Windows-based PC is made up of two fundamentals: the hardware; and the software that runs on the hardware. We can see the hardware if we pop the lid and take a peek inside: the CPU, the RAM, the storage (SSD or HDD) and the inputs/outputs (I/O).
