|

|
30 BUGS
|
|
|
31 I have been unable to figure out how to use the volume feature, so no
|
|
444
|
32 attempt has been made to honor the volume arg of play_sound_*
|
|
428
|
33 This means that all sounds are played at 100%.
|
|
|
34 The gain parameter can be set by using the hp-play-gain variable.
|
|
|

|
|
36 NOTES
|
|
|
37 This file is mostly based on the player program found in the examples
|
|
|
38 directory of the audio software delivered on our machines. The path I
|
|
|
39 found it under was /usr/audio/examples/player.c
