1# Audio Error Codes 2 3> **NOTE** 4> 5> This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](errorcode-universal.md). 6 7## 6800101 Invalid Parameter 8 9**Error Message** 10 11Invalid parameter. 12 13**Description** 14 15A parameter passed in the API is invalid. 16 17**Possible Causes** 18 19The parameter is invalid. For example, the parameter value is not within the range supported. 20 21**Solution** 22 23Pass the correct parameters in the API. 24 25## 6800102 Memory Allocation Failure 26 27**Error Message** 28 29Memory allocation failure. 30 31**Description** 32 33When the API is called, the memory fails to be allocated or a null pointer occurs. 34 35**Possible Causes** 36 371. The system does not have sufficient memory for mapping. 382. Invalid instances are not destroyed in time to release the memory. 39 40**Solution** 41 421. Destroy the existing instances. 432. Create a new instance. If the creation fails, stop related operations. 44 45## 6800103 Unsupported State 46 47**Error Message** 48 49Unsupported state. 50 51**Description** 52 53This operation is not allowed in the current state. 54 55**Possible Causes** 56 57The operation is not supported in the current state. For example, data is played before streams are started. 58 59**Solution** 60 611. Check whether this operation is supported in the current state. 622. Switch the instance to the correct state and perform the operation. 63 64## 6800104 Unsupported Parameter Value 65 66**Error Message** 67 68Unsupported parameter value. 69 70**Description** 71 72The parameter value is not supported. 73 74**Possible Causes** 75 76The value of the input parameter is not within the range supported. 77 78**Solution** 79 801. Check the enums or other input parameters supported by the API. 812. Use a supported value. 82 83## 6800105 Processing Timeout 84 85**Error Message** 86 87Processing timeout. 88 89**Description** 90 91Waiting for external processing times out. 92 93**Possible Causes** 94 95Waiting for external processing times out. For example, waiting for the application to fill in audio data times out. 96 97**Solution** 98 99Control the time of the write operation, for example, adding delayed processing. 100 101## 6800201 Too Many Audio Streams 102 103**Error Message** 104 105Too many audio streams. 106 107**Description** 108 109The number of audio streams reaches the upper limit. 110 111**Possible Causes** 112 113Invalid audio streams are not released in time. 114 115**Solution** 116 117Release audio streams that are no longer used. 118 119## 6800301 System Error 120 121**Error Message** 122 123System error. 124 125**Description** 126 127The system processing is abnormal. 128 129**Possible Causes** 130 131The system processing is abnormal, for example, system service restart or IPC exceptions. 132 133**Solution** 134 135Create the service again. 136
