The following options are available:
-i
If the audio device cannot be opened, exit now rather than wait for it.
-v
Set the volume (gain) to volume. This value must be between 0 and 255.
-b
Set the balance to balance. This value must be between 0 and 63.
-p
Set the output port to port. The valid values of port are “speaker”, “headphone” and “line”.
-d
Set the audio device to be device. The default is /dev/sound.
-f
Force playing, even if the format is unknown. The -f flag can be used in addition with the following flags to change the number of channels, encoding, precision and sample rate.
-c
when combined with the -f option, sets the number of channels to its argument.
-e
when combined with the -f option, sets the encoding to its argument. Possible values are mulaw, ulaw, alaw, slinear, linear, ulinear, adpcm, ADPCM, slinear_le, linear_le, ulinear_le, slinear_be, linear_be, ulinear_be, mpeg_l1_stream, mpeg_l1_packets, mpeg_l1_system, mpeg_l2_stream, mpeg_l2_packets, and mpeg_l2_system.
-P
when combined with the -f option, sets the precision to its argument. This value must be either 4, 8, 16, 24 or 32.
-s
when combined with the -f option, sets the sample rate to its argument. This value must be a valid value for the audio device or an error will be returned.
