.SH SYNOPSIS
\fBalsa-delay\fP \fI[options]\fP \fIrequested_delay_in_ms\fP [\fIoutput_card\fP[,\fIdevice\fP]]

.SH DESCRIPTION
\fBalsa-delay\fP is a command\-line utility to setup an audio
delay. The snd-aloop ALSA driver is used to send all PCM streams
back to the user space and the alsaloop utility is used to send
this stream to a real hardware.

The parameter \fIoutput_card\fP is ALSA card index (number) or
string card identifier. The parameter \fIdevice\fP is ALSA device number.

Use \fIaplay -l\fP to list available cards and devices.
