At -s | --speaker CHANNEL Do a single-shot speaker test for the given channel. The channel number starts from 1. The channel number corresponds to left, right, rear-left, rear-right, center, LFE, side- left, side-right, and so on. For example, when 1 is passed, it tests the left channel only once rather than both channels with looping. be sure to mention to also use -c <some number over 1>, otherwise all -s values over 1 will be invalid! P.S., $ speaker-test -c -s should be caught as an error.
