# Sound problems?

If your sound is not working, it could be that Fatdog64 just doesn't have a driver for it.

Or, more likely, the volume is muted or the wrong sound card has been chosen as the default.

Even if you only have one sound card, often that card will have several functions driven by different drivers, so that it looks like multiple sound cards to Fatdog64.


## Volume

The volume icon in the task bar only adjusts the Master volume, not any other channels.

To adjust the volume, open AlsaMixer (found under Sound in the Control Panel, or by left clicking on the sound icon in the tray and selecting "Mixer".)

This application does not use the mouse; you'll need to use the arrow keys to move and to adjust the volumes.

The **m** key mutes and unmutes a channel.

Note that you can turn the volume up on a channel and still have it muted, so make sure that mute is off if you want a setting to be in effect.

At the bottom of each channel it should show **00**; if it shows **MM** it's muted.


## Headphones and external speakers

Also in AlsaMixer, the Auto-Mute column allows you to choose what happens when headphones or other speakers are plugged in:  whether the built-in speakers will be muted or still play.  Use the up and down arrows to select.


## Default Sound Card

To select the default sound card start the Fatdog Default Soundcard Wizard, found in Control Panel under Sound.

Select the device to use as the default and then use AlsaMixer again to make sure everything is turned up and unmuted.

You also use the same wizard to send audio to a bluetooth device.
