Pan control not working in 3.7.3

Thoughts, ideas, solutions? Have been using Audacity for years, first time I’ve had this problem

I cannot replicate this.

Works for me on W10 with 3.7.3

I’ve uninstalled and reinstalled Audacity, but no luck. The slider moves but the actual pan position of the track does not change. Using Windows 11.

Defective headphone cable, or the wrong type of headphone connector, could negate the effect of panning.

Windows can be configured to output mono sound, which would also negate panning.

Nope. Works for me. 3.7.3 on W10.
Does the viewed region span enough of your screen that panning WOULD work?
