I tried speaker-test and it doesn't support S24_LE: # speaker-test -h speaker-test 1.1.9 Usage: speaker-test [OPTION]... -h,--help help -D,--device playback device -r,--rate stream rate in Hz -c,--channels count of channels in stream -f,--frequency sine wave frequency in Hz -F,--format sample format -b,--buffer ring buffer size in us -p,--period period size in us -P,--nperiods number of periods -t,--test pink=use pink noise, sine=use sine wave, wav=WAV file -l,--nloops specify number of loops to test, 0 = infinite -s,--speaker single speaker test.
