Troubleshooting
Re-saving a SONAR X1 project file in an older version may permanently remove the project data
described above.
Template files saved from SONAR X1 will not load in earlier versions of SONAR. This is because of
changes made to SONAR's view persistence code in SONAR X1.

Windows Vista
The following issues are known problems with Microsoft Windows Vista (as of Vista SP1):
• In WDM or WASAPI mode for some audio devices, SONAR reports an “Unable to Open...” error
when attempting to record with multiple input drivers. This may occur when SONAR attempts to
open more than one input for recording when Allow Arm Changes During Record Or Playback
is selected in Edit > Preferences > Project - Record. This problem is most likely caused by the
driver disallowing multiple inputs to be used simultaneously.
• As of Vista SP1, WaveRT drivers for onboard audio devices do not work in Vista X64 while
running the 32 bit version of SONAR. This is due to a problem with WOW64 in Windows Vista
X64 that has been reported to Microsoft. This issue has been addressed by Microsoft Windows 7.
WASAPI wave profiling in Windows Vista
Prior to wave profiling in WASAPI, we recommend that you profile your audio hardware at least once
in WDM mode. This allows the WASAPI wave profiler to pick up the driver preferred DMA settings
from WDM.
This is required because some drivers perform better with these settings and WASAPI does not
provide any mechanism to get the driver preferred values. This issue has been addressed by
Microsoft Windows 7.

Windows 7
In WASAPI mode if you set the audio latency lower than 4 milliseconds, you will get an error
message that the audio device does not support the current format. This is a known bug in the
shipping version of Windows 7 and has been reported to Microsoft.
