##### Sound Function - Sound Module Control Function

# sdPstmSetBaseVol

Sets the base volume of a PCM Stream port

### FORMAT

`

  SDE_ERR sdPstmSetBaseVol( handle, base_vol )
  SDPSTM handle
  Sint8 base_vol

`

### PARAMETER

  `handle` | Object handle
  `base_vol` | Base volume

### RETURN

  SDE_ERR_NO_INIT | The Sound Library has not been initialized |
  SDE_ERR_HANDLE_NULL | The handle is NULL |

### DESCRIPTION

  Sets the base volume of channel's PCM Stream port. The range of "base_vol," which specifies the base volume, is 000H (minimum volume) to 007FH (maximum volume).

### NOTE

  Actual output volume of a port results from combining this function setting and the relative volume setting of sdPstmSetVol. Therefore, if this functions sets the volume to 007FH, the volume cannot be further increased by specifying a higher level with `sdPstmSetVol().`
