Playback (Windows Mme) - RME Audio DIGI32/8 User Manual

8.3 Playback (Windows MME)

DIGI32/8 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, DIGI32/8 must be selected as the output device. This can
often be found in the Options, Preferences or Settings menus under Playback Device, Audio
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 DIGI32 series fullest potential.
We strongly recommend switching all system sounds off (via >Control Panel /Sounds<). Also
DIGI32/8 should not be the Preferred Device for playback, as this could cause loss of syn-
chronization 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 picture to the
right shows the
smallest buffer setting
for a crackle-free 24
bit operation in a
computer with 200
MHz.
More or larger buffers
produce an even
higher defence
against distur-bance,
but also cause a lon-
ger delay in playing
back the data. In case
of synchronized audio
to MIDI playback be
sure to activate the
checkbox 'Get play
position from audio
driver' when available
in your program.
Because the DIGI32/8 reports the actual play position correct (even in record where this is
neccessary for chase lock sync) there will be no sync problems when working in a mixed au-
dio/MIDI environment even with higher buffer settings.
