<title>Audio Settings</title>
<body>
<p>The <b outputclass="bold">Audio</b> section in a virtual machine's <b outputclass="bold">Settings</b> window
determines whether the VM will detect a connected sound card, and if the audio output should be played on the host
system. </p>
<p>To enable audio for a guest, select the <b outputclass="bold">Enable Audio</b> check box. The following settings
are available: </p>
<ul>
<li>
<p><b outputclass="bold">Host Audio Driver:</b> The audio
driver that <ph conkeyref="vbox-conkeyref-phrases/product-name"/> uses on the host.
</p>
<p>The <b outputclass="bold">Default</b> option is enabled by default for all new VMs. This option selects the
best audio driver for the host platform automatically. This enables you to move VMs between different
platforms without having to change the audio driver. </p>
<p>On a Linux host, depending on your host configuration, you can select between the OSS, ALSA, or the
PulseAudio subsystem. On newer Linux distributions, the PulseAudio subsystem is preferred. </p>
<p>Only OSS is supported on Oracle Solaris hosts. The Oracle Solaris Audio audio backend is no longer supported
on Oracle Solaris hosts. </p>
</li>
<li>
<p><b outputclass="bold">Audio Controller:</b> You can
choose between the emulation of an Intel AC'97 controller, an
Intel HD Audio controller, or a SoundBlaster 16 card.
</p>
</li>
<li>
<p><b outputclass="bold">Enable Audio Output:</b> Enables
audio output only for the VM.
</p>
</li>
<li>
<p><b outputclass="bold">Enable Audio Input:</b> Enables
audio input only for the VM.
</p>
</li>
</ul>
