Issue Cause Error message Resolution
The SDK doesn't load AlexaClientSDKConfig.jsondoesn't reference a database file miscDatabase: E SQLiteMiscStorage:createFailed:reason=Could not load config value,key=databaseFilePath Open AlexaClientSDKConfig.json and find the `databaseFilePath` entry. Make sure it's linking to a database. To see an example of this, run the script to populate the field for you.
Amazon Music won't play The device isn't set with the correct date. This causes certificate issues when contacting Amazon server curlEasyPerformFailed:error=Peer certificate can't authenticate with the provided CA certificates Change the date on the device to the current date. For example, to change the date to Jan 31, 2018: date +%Y%m%d -s "20180131". To change the time: date +%T -s "16:11:00"
No audio output The SDK is referencing the incorrect audiosink element The SDK automatically selects the best audiosink based on your system configuration. This can cause issues depending on how you build the SDK Run this command: gst-launch-1.0 -m audiotestsrc ! autoaudiosink. If the system is working, a test tone plays. If the system isn't working, a test tone doesn't play

Use -m to show which audiosink you've set up. If needed, change the sink in the AlexaClientSDKConfig.json file


Issue Cause Error message Resolution

You can pass in CXX flags to the SampleApp CMake command like so: -DCMAKE_CXX_FLAGS:STRING="-D_GLIBCXX_USE_CXX11_ABI=0 -pg"
