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.

|
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
