Crackling sound with ALSA from an USB sound card after ...
https://unix.stackexchange.com/questions/469372/crackling-sound-with-alsa-from-an-usb-sound-card-after-resuming-from-suspend
After resuming, the USB sound card’s audio output is broken and irregularly produces crackling noises. What is possibly causing this? How can I fix this? Plugging the USB sound card in and out neither produces this issue nor does it solve it. I don’t have a ~/.asoundrc. Some information. Here is the dmesg output
ALSA USB Headset Crackling Noise - Arch Linux
https://bbs.archlinux.org/viewtopic.php?id=161084
The crackling noises occured only sometimes and only when playing 48kHz sound files. ALSA or PulseAudio made no difference. My onboard card worked fine. I've fixed it by forcing PulseAudio to 44.1kHz regardless of the sampling rate of the file by adding default-sample-rate = 44100 alternate-sample-rate = 44100

ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred. The issue appears to be related to buffer size / sampling rate since setting different values of those in ~/.asoundrc changes the amount of crackling (although I couldn't manage to find a combination that would eliminate it completely).

[ubuntu] Obnoxious crackling sound from usb audio …

The speakers had a crackle or clicking sounds when playing videos. This was due to a mismatch in the audio rates. Looking at the output of "sudo lsusb -v" the audio should be able to handle several rates, so maybe the problem is in the linux driver not being complete ?
