Troubleshooting the Waveform Audio Driver Test (Windows Embedded CE 6.0)
1/6/2010
The following table shows troubleshooting tips for the Waveform Audio Driver Test.
| Item | Solution |
|---|---|
The Volume Tests that use the Mixer are skipping. |
These tests will skip if the power manager is not present on the system. |
The Power Management Tests are skipping. |
These tests will skip if the power manager is not present on the system. |
The Capture Multiple Stream Tests are skipping. |
These tests will skip if the device driver does not support multiple capture streams. |
An access violation occurs during the Buffer Freed Tests. |
This is expected behavior if you are running the tests from Platform Builder. You must set up Platform Builder to only break into the debugger on an unhandled access violation exception. To set up this property, go to menu item Debug and select Exceptions, or press Ctrl+Alt+E in Platform Builder. |
If the build verification test (test case 100) determines that required functionality is not present, it may skip other test cases.
Test case 4001 (tests waveOutSetVolume and waveOutGetVolume) can produce false failures when running in interactive mode. This issue will be resolved in a future update.
In order for the Waveform Audio Driver Test to function correctly you must have included the waveform audio component, SYSGEN_AUDIO, as well as an audio driver, BSP_WAVEDEV_<driver_name>, in your OS build. Some board support packages (BSPs) include an audio driver by default.
