|
#####
|
||
|
|
|
||
|
|
The audio driver is ported from OpenBSD 5.7 and includes support for
|
||
|
|
Intel HD Audio as well as for Ensoniq AudioPCI (ES1370) compatible
|
||
|
|
soundcards. The HDA driver works on real hardware and Virtualbox
|
||
|
|
whereas the ES1370 driver is only used in Qemu.

Usage
|
||
|
|
=====
|
||
|
|
|
||
|
|
You have to prepare the contrib sources for this repository by
|
||
|
|
executing _tool/ports/prepare_port dde_bsd_. Also you need to make
|
||
|
|
sure to add the 'dde_bsd' repository to the REPOSITORIES variable
|
||
|
|
in your 'etc/build.conf'.
|
||

Example
|
||
|
|
=======
|
||
|
|
|
||
|
|
The driver can be tested by executing the run script 'run/audio_out.run'.
|
||
|
|
This example plays a sample file in a loop. The file format is header less
|
||
|
|
two channel float 32 at 44100 Hz. You may use the 'sox' utility to create
|
||
|
|
these audio files:
|
||
|
|
|
||
|
|
! sox -c 2 -r 44100 foo.wav foo.f32
