     3== Introduction ==
     4
     5HelenOS supports audio devices. Getting basic audio output is very easy. We'll explain all the necessary steps here.
     6
     7== Audio on Hardware ==
     8
     9HelenOS supports Intel High Definition Audio thus it should work with the on-board audio device of any not-too-ancient PC.
     10
     11== Audio in Qemu ==
     12
     13In 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
     14
     15{{{
     16-device intel-hda -device hda-duplex
     17}}}
     18
     19Don't use the sb16 device - current versions of Qemu have broken sb16 support.
     20
     21== Say hello ==
     22
     23To test sound type into the terminal:
     24{{{
     25# wavplay demo.wav
     26}}}
     27
     28== Amiga-style modules ==
     29
     30The {{{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:
     31
     32{{{
     33# modplay <my_module.mod>
     34}}}
