8.2 Playback
The HDSP system 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, HDSP must be selected as output device. This can often
be found in the
Options, Preferences
or
Settings
menus under
Playback Device, Audio Devices,
Audio
etc. We recommend using 24-bit resolution for playback, to make full use of the HDSP’s
potential.
We strongly recommend switching all system sounds off (via >Control Panel /Sounds<). Also
HDSP 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
applications, found in the directory
\rmeaudio.web\english\techinfo\conf
.
The screenshot below shows a typical configuration dialog as displayed by a (stereo) wave
editor. Audio data is sent to the chosen device, which can be one of 6 stereo outputs. 3 of these
outputs are virtual and will be mixed by TotalMix to any of the existing 3 hardware outputs.
Increasing the number and/or size of audio buffers may prevent the audio signal from breaking
up, but also increases latency i.e. output is delayed. For synchronized playback of audio and
MIDI (or similar), be sure to activate the checkbox ‘Get position from audio driver’.
