# Audio Error Codes > **NOTE** > > This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](errorcode-universal.md). ## 6800101 Invalid Parameter **Error Message** Invalid parameter. **Description** A parameter passed in the API is invalid. **Possible Causes** The parameter is invalid. For example, the parameter value is not within the range supported. **Solution** Pass the correct parameters in the API. ## 6800102 Memory Allocation Failure **Error Message** Memory allocation failure. **Description** When the API is called, the memory fails to be allocated or a null pointer occurs. **Possible Causes** 1. The system does not have sufficient memory for mapping. 2. Invalid instances are not destroyed in time to release the memory. **Solution** 1. Destroy the existing instances. 2. Create a new instance. If the creation fails, stop related operations. ## 6800103 Unsupported State **Error Message** Unsupported state. **Description** This operation is not allowed in the current state. **Possible Causes** The operation is not supported in the current state. For example, data is played before streams are started. **Solution** 1. Check whether this operation is supported in the current state. 2. Switch the instance to the correct state and perform the operation. ## 6800104 Unsupported Parameter Value **Error Message** Unsupported parameter value. **Description** The parameter value is not supported. **Possible Causes** The value of the input parameter is not within the range supported. **Solution** 1. Check the enums or other input parameters supported by the API. 2. Use a supported value. ## 6800105 Processing Timeout **Error Message** Processing timeout. **Description** Waiting for external processing times out. **Possible Causes** Waiting for external processing times out. For example, waiting for the application to fill in audio data times out. **Solution** Control the time of the write operation, for example, adding delayed processing. ## 6800201 Too Many Audio Streams **Error Message** Too many audio streams. **Description** The number of audio streams reaches the upper limit. **Possible Causes** Invalid audio streams are not released in time. **Solution** Release audio streams that are no longer used. ## 6800301 System Error **Error Message** System error. **Description** The system processing is abnormal. **Possible Causes** The system processing is abnormal, for example, system service restart or IPC exceptions. **Solution** Create the service again.
