(Sorry for the inconvenience)
Beginning with PC-BSD 9.1, a Sound Configuration icon is available from Control Panel. This utility automatically determines which audio devices are available and provides a button to play a test sound. An example of the Sound Configuration screen is shown in Figure 8.9a.
Figure 8.9a: Sound Configuration Utility
To determine which audio devices are available, click the drop-down menu. In the example shown in Figure 8.9b, this system has four available sound devices with the FreeBSD device names pcm0 to pcm3. The default device is the Conexant CX20590 sound card.
Figure 8.9b: Selecting the Audio Device
To change the default audio device, select the desired device from the drop-down menu and test that it works by clicking the "Test sound" button. To make the change permanent, click the "Apply" button.
If the desired device does not appear in the drop-down menu, it means that PC-BSD did not recognize the device. See the section Finding Help. When reporting your problem, include your version of PC-BSD and the name of your sound card.
