If removing module-suspend-on-idle is not sufficient to reduce audio latency in PulseAudio
try this to reconfigure PulseAudio
tee ~/.config/pulse/daemon.conf <<< 'resample-method = speex-float-3
default-sample-format = s24le
default-sample-rate = 48000
enable-deferred-volume = 0'
To check latency for PulseAudio outputs
pactl list sinks
To check latency for audio stream inputs playing audio via PulseAudio
pactl list sink-inputs
