Check whether the left and right audio channels are routed correctly on speakers, headphones, earbuds, or your current output device.

How to read the result
This test is about channel routing, not tone quality.
- Left test plays on the left only — stereo routing is behaving correctly.
- Left test plays on the right — channels are swapped somewhere in the chain.
- Both sides play during a one-channel test — mono mixing or channel collapse is likely.
- One side stays silent — check cable, balance, output routing, or speaker / headphone hardware.
If the channels work but the sound still feels weak or distorted, move to the Speaker Frequency Test.
