26 PURPOSE
|
|
|
27 Play .au sound files on hp9000s700
|
|
|
28 BUGS
|
|
|
29 I have been unable to figure out how to use the volume feature, so no
|
|
|
30 attempts has been made to honor the volume arg of play_sound_*
|
|
274
|
31 This means that all sounds are played at 100%.
|
|
|
32 The gain parameter can be set by using the hp-play-gain variable.

35 This file is mostly based on the player program found in the examples
|
|
|
36 directory of the audio software delivered on our machines. The path I

37 found it under was /usr/audio/examples/player.c
