int mixer_all_get_volume ( void  )

Returns the average volume of all available mixers (range 0..100).

Returns -1 if no mixer can be queried.

void mixer_all_set_software_volume ( unsigned  volume)

Similar to mixer_all_set_volume(), but sets the volume only for software mixers.

See software_mixer_plugin. This function cannot fail, because the underlying software mixers cannot fail either.

bool mixer_all_set_volume ( unsigned  volume)

Sets the volume on all available mixers.

Parameters:
volumethe volume (range 0..100)
