From time to time the audio is locked as a scratched CD (example: a normal-rmal audio playing). and this same problem was accompanied by an interference similar to when a horn is connected abruptly to the pc, but the latter I have already been able to repair it

my specifications:
Operating System: KDE neon 5.18
KDE Plasma Version: 5.18.2
KDE Frameworks Version: 5.67.0
Qt Version: 5.14.1
Kernel Version: 5.3.0-40-generic
OS Type: 64-bit
Processors: 4 × AMD A6-6310 APU with AMD Radeon R4 Graphics
Memory: 6.7 GiB

In which application? I will move the post to the correct subforum as soon as I have that info

From what I've researched I thought it involves pulseaudio. I really don't know if I go in this forum.

I did not understand the organization of kdeforum, sorry for the inconvenience

You didn't answer my question: which application do you run with audio that causes problems?
