Changes various settings of a sound device (master mute, master volume, etc.)
SoundSet, NewSetting [, ComponentType, ControlType, DeviceNumber]
| NewSetting | Percentage number between -100 and 100 inclusive (it can be a floating point number or expression). If the number begins with a plus or minus sign, the current setting will be adjusted up or down by the indicated amount. Otherwise, the setting will be set explicitly to the level indicated by NewSetting. For ControlTypes with only two possible settings -- namely ONOFF, MUTE, MONO, LOUDNESS, STEREOENH, and BASSBOOST -- any positive number will turn on the setting and a zero will turn it off. However, if the number begins with a plus or minus sign, the setting will be toggled (set to the opposite of its current state). |
| ComponentType | If omitted or blank, it defaults to the word MASTER. Otherwise, it can be one of the following words: MASTER (synonymous with SPEAKERS), DIGITAL, LINE, MICROPHONE, SYNTH, CD, TELEPHONE, PCSPEAKER, WAVE, AUX, or ANALOG (in addition, in v1.0.37.06+ it can be N/A; and in v1.0.42.04+ it can be HEADPHONES). If the sound device lacks the specified ComponentType, ErrorLevel will indicate the problem. The component labeled Auxiliary in some mixers might be accessible as ANALOG rather than AUX. If a device has more than one instance of ComponentType (two of type LINE, for example), usually the first contains the playback settings and the second contains the recording settings. To access an instance other than the first, append a colon and a number to this parameter. For example: Analog:2 is the second instance of the analog component. |
| ControlType | If omitted or blank, it defaults to VOLUME. Otherwise, it can be one of the following words: VOLUME (or VOL), ONOFF, MUTE, MONO, LOUDNESS, STEREOENH, BASSBOOST, PAN, QSOUNDPAN, BASS, TREBLE, or EQUALIZER. In v1.0.37.06+, it can also be the number of a valid control type (see soundcard analysis script). If the specified ComponentType lacks the specified ControlType, ErrorLevel will indicate the problem. |
| DeviceNumber | If this parameter is omitted, it defaults to 1 (the first sound device), which is usually the system's default device for recording and playback. Specify a number higher than 1 to operate upon a different sound device. This parameter can be an expression. |
ErrorLevel is set to 0 if the command succeeded. Otherwise, it is set to one of the following phrases:
| Invalid Control Type or Component Type |
| Can't Open Specified Mixer |
| Mixer Doesn't Support This Component Type |
| Mixer Doesn't Have That Many of That Component Type |
| Component Doesn't Support This Control Type |
| Can't Get Current Setting |
| Can't Change Setting |
To discover the capabilities of the sound devices (mixers) installed on the system -- such as the available component types and control types -- run the soundcard analysis script.
When SoundSet changes the volume of a component, all of that component's channels (e.g. left and right) are set to the same level. In other words, any off-center "balance" that may have been set previously is lost. This can be avoided for the WAVE component by using SoundSetWaveVolume instead, which attempts to preserve the existing balance when changing the volume level.
Use SoundGet to retrieve the current value of a setting.

; BASIC EXAMPLES: SoundSet, 50 ; Set the master volume to 50% SoundSet +10 ; Increase master volume by 10% SoundSet -10 ; Decrease master volume by 10% SoundSet, 1, Microphone, mute ; mute the microphone SoundSet, +1, , mute ; Toggle the master mute (set it to the opposite state) SoundSet, +20, Master, bass ; Increase bass level by 20%. if ErrorLevel MsgBox, The BASS setting is not supported for MASTER.
