8.3 Playback (Windows MME)
DIGI96/8 PST
can play back audio data only in supported formats (sample rate, bit
resolution). Otherwise an error message appears (for example at 22 kHz and 8 bit).
In the audio application being used, DIGI96/8 PST must be selected as the output device. This
can often be found in the
Options, Preferences
or
Settings
menus under
Playback Device, Au-
dio Devices, Audio
etc. Only a few programs exclusively use Windows'
Preferred Playback
Device
. This setting can be changed in >Control Panel /Multimedia /Audio<. We recommend
using 24-bit resolution for playback to use the DIGI96 series fullest potential.
We strongly recommend switching all system sounds off (via >Control Panel /Sounds<). Also
DIGI96/8 PST
should not be the
Preferred Device
for playback, as this could cause loss
of synchronization and unwanted noises. If you feel you cannot do without system sounds, you
should consider buying a cheap Blaster clone and select this as
Preferred Device
in >Control
Panel /Multimedia /Audio<.
The RME Driver CD includes step by step instructions for configuring many popular audio ap-
plications. Start setup.htm or setup2.htm (in the
\rmeaudio.web\techinfo\
directory).
The screenshot to the
right shows a typical con-
figuration dialog as
displayed by a (stereo)
wave editor. In ADAT
mode a playback is done
using the currently chosen
stereo pair. In SPDIF
mode playback always
uses channels 1+2.
Increasing the number
and/or size of audio buf-
fers may prevent the au-
dio signal from breaking
up, but also increases
latency i.e. output is de-
layed. For synchronized
playback of audio and
MIDI, be sure to activate
the checkbox ‘Get position from audio driver’. Even at higher buffer settings in a mixed Au-
dio/MIDI environment, sync problems will not arise because the
DIGI96/8 PST
always
reports the current play position correctly (even while recording - essential for chase lock syn-
chronization).
