Sound Blaster 16 Automatic Gain Control Setting Is Lost

• Microsoft Windows 95

SYMPTOMS

If you use automatic gain control (AGC) for WaveIn when you are recording using a microphone connected to a Sound Blaster 16 sound card, AGC is turned off when you restart Windows 95.

CAUSE

When you shut down Windows 95, the Creative Labs sound card driver overrides the WaveIn AGC setting with the VoiceIn AGC setting (which is turned off, by default).

RESOLUTION

To resolve this issue, follow these steps:

1. Click the Start button, click Run, type "sndvol32.exe" (without quotation marks) in the Open box, and then click OK.

   NOTE: The Sndvol32.exe tool is installed by default when Windows 95 detects a sound card. If this tool is not installed, you can install it using the Add/Remove Programs tool in Control Panel.

2. On the Options menu, click Properties.

3. Click the Other option button, and then click OK.

4. If there is no Advanced button in the Microphone section, click Advanced Controls on the Options menu.

5. Click the Advanced button in the Microphone section.

6. Click the AGC For VoiceIn check box to select it, and then click Close.

7. Repeat steps 2-6, using Recording options.

   NOTE: You must repeat steps 2-6 using the Recording options to retain the AGC settings.

8. Close the Volume Control tool.
