== Introduction ==

HelenOS supports audio devices. Getting basic audio output is very easy. We'll explain all the necessary steps here.

== Audio on Hardware ==

HelenOS supports Intel High Definition Audio thus it should work with the on-board audio device of any not-too-ancient PC.

== Audio in Qemu ==

In Qemu HelenOS can support audio via Intel High Definition Audio device. Just use {{{ew.py}}} and you will get it automatically. Alternatively, run Qemu with the options 

{{{
-device intel-hda -device hda-duplex
}}}

Don't use the sb16 device - current versions of Qemu have broken sb16 support.

== Say hello ==

To test sound type into the terminal:
{{{
# wavplay demo.wav
}}}

== Amiga-style modules ==

The {{{modplay}}} command can play Amiga-style modules (.mod and .xm). Find one and get it onto your HelenOS system (e.g. on a USB stick or build it into the initrd). Play it using the command:

{{{
# modplay <my_module.mod>
}}}
