Small distortion in `speaker-test -t sine` when changing the volume

[Paul Menzel <pmenzel@xxxxxxxxxxxxx>]

Dear Linux folks,


On the Intel Kaby Lake laptop Dell XPS 13 9360/0596KF, BIOS 2.21.0 
06/02/2022, with Realtek ALC3246, while debugging a distortion with 
*mpv* 0.38.0-1+b1 and *pipewire* 1.2.5-1, I noticed, `speaker-test -t 
sine` works without crackling/distorting, but when changing the volume 
with the function keys or the slider in the GNOME Shell’s system menu 
[1] or the GNOME settings, there is a small distortion at each step.

I am currently using Debian sid/unstable with GNOME and PipeWire and 
Linux 6.12-rc1+ (upload of `/sbin/alsa-info` [2]).


Kind regards,

Paul
