Hello, I'm facing an issue with my Logitech G Pro X headset. The cable with the potentiometer seems to behave strangely. When I use the cable at full volume, the left audio channel becomes noticeably quieter, but lowering the volume slightly fixes it. However, when I move the cable down a bit, everything works fine again. The headset is still under warranty, yet the service person couldn't find any problem when replacing the cable.

I measured the resistance on both channels and found some discrepancies. Both measurements were taken at maximum volume with the potentiometer in place. The next two channels appear to be a microphone, consistently reading 10 kΩ, while the last one seems to be a ground. I suspect these first two are L and R channels, differing by about 50–100 ohms depending on the pot position. This variation is usually around 50–100 ohms across different settings.

I expected a noticeable jump in resistance at full volume, which would explain why the left channel drops when volume increases. But there isn’t one. It seems like the cable’s behavior changes unexpectedly. The resistance appears very high—starting near zero at the lowest setting and rising to 10 kΩ or more at maximum volume. This makes it seem like a large jump, but I feel like 10,000 ohms is too much for an audio cable.

The other cable without the potentiometer shows no resistance at all during measurement. How can I test this properly? Do I need to adjust my method? Is a 50–100 ohm difference between these values enough to justify a warranty replacement? The left channel drop only occurs at maximum volume, which is confusing when trying to verify it with a multimeter.
