NAME

alsadelay - a command to (re)initialize sound hardware

SYNOPSIS

alsa-delay [options] requested_delay_in_ms [output_card[,device]]

DESCRIPTION

alsa-delay 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 output_card is ALSA card index (number) or string card identifier. The parameter device is ALSA device number.

Use aplay -l to list available cards and devices.

--pctl=<DEV>: Force playback control device.
--cctl=<DEV>: Force capture control device.
--one=<ARG>: Pass this argument to last thread.

--mix=<ARG>: Redirect ALSA mixer controls to OSS mixer (default is Master).
