 ## Introduction
 
-You can use audio playback APIs to convert audio data into audible analog signals and play the signals using output devices. You can also manage playback tasks. For example, you can start, suspend, stop playback, release resources, set the volume, seek to a playback position, and obtain track information.

+
+**Error Message**
+
+No memory.
+
+**Description**
+
+Failed to allocate memory.
+
+**Possible Causes**
+
+1. The number of instances exceeds 16.
+2. The new or malloc process fails, causing a null pointer.
+
+**Solution**
+
+Destroy this instance and re-create it. If the re-creation fails, stop related operations.
+
+## 5400102 Unsupported Operation
+
+**Error Message**
+
+Operate not permit.
+
+**Description**
+
+This operation is not allowed.
+
+**Possible Causes**
+
+This operation is not allowed in the current state.
+
+**Solution**
+
+Switch the instance to the correct state and perform the operation.
+
+## 5400103 I/O Error
+
+**Error Message**
+
+IO error.
+
+**Description**
+
+An I/O error occurs.
+
+**Possible Causes**
+
+The data interaction between the media and other modules (graphics, audio, network, HDI, and camera) is abnormal.
+
+**Solution**
+
+Ensure that the network is normal, destroy this instance, and re-create it. If the re-creation fails, stop related operations.
+
+## 5400104 Operation Timeout
+
+**Error Message**
+
+Time out.
+
+**Description**
+
+The operation timed out.

+**Possible Causes**
+
+1. The network connection times out.
+2. Accessing other modules times out.
+
+**Solution**
+
+1. Check whether the network is normal.
+2. Destroy this instance and re-create it. If the re-creation fails, stop related operations.
+
+## 5400105 Play Service Dead
+
+**Error Message**
+
+Service died.
+
+**Description**
+
+The playback service is dead.
+
+**Possible Causes**
