Sound is pitched and slowed down when going through the sound card of a mixer controller

[mYnDstrEAm]

First of all I'm not sure if that's a bug in ALSA and if so if this is the right repo to file it.

When I connect my mixer to my Debian11/KDE machine the sound is slowed and pitched down. Sometimes it takes days or weeks until this effect occurs, most of the time everything works well and I don't know what causes this to occur.

See https://unix.stackexchange.com/questions/572895/linux-sound-is-pitched-and-slowed-down-when-going-through-the-sound-card-of-a-mi (and comments below)

aplay -l says the driver is module-alsa-card.c. The track is still pitched down when played with aplay.

I'm not sure if the sound really is slowed down or if it was changed in a slightly different way in the past (had this bug for years now), but right now when I use my mixer rather than internal audio, the sound is lower in pitch. Let me know if there's something I could check like something in some logs.
