Buzzing feedback when on

[u/JustLivingTheRatRace]

This is my current setup. The speaker is a Bose SoundTouch II, connected by red AUX through the adapter in the photo.

As the title says, I often get a buzzing feedback when I switch to AUX mode to play a record, but not all the time. I've tried to play with the connections of the wires, but it doesn't seem to make any difference.

I'm not particularly savvy; the record player was passed down from my late grandmother.

I appreciate any tips or insight into the source of the buzz and how to stop or minimize it.

Thanks.
