+## cl.multimedia.1 音频C接口流类型枚举声明变更
+
+对于在API10中已经新增的音频C接口，音频输出流类型错写为AUDIOSTREAM_TYPE_RERNDERER，需要修正为AUDIOSTREAM_TYPE_RENDERER。
+
+**变更影响**
+
+对于已发布的C接口，可能影响三方应用的兼容性。
+
+**关键的接口/组件变更**
+
+修改前的接口原型：
+
+ ```C
+enum OH_AudioStream_Type {
+    /**
+     * The type for audio stream is renderer.
+     */
+    AUDIOSTREAM_TYPE_RERNDERER = 1,
+
+    /**
+     * The type for audio stream is capturer.
+     */
+    AUDIOSTREAM_TYPE_CAPTURER = 2
+};
+ ```
+
+修改后的接口原型：
+
+ ```C
+enum OH_AudioStream_Type {
+    /**
+     * The type for audio stream is renderer.
+     */
+    AUDIOSTREAM_TYPE_RENDERER = 1,
+
+    /**
+     * The type for audio stream is capturer.
+     */
+    AUDIOSTREAM_TYPE_CAPTURER = 2
+};
+ ```
+
+**适配指导**
+
+开发人员需要在使用音频输出流类型AUDIOSTREAM_TYPE_RERNDERER时，修改为AUDIOSTREAM_TYPE_RENDERER。例如：
+
+修改前
+
+```C
+OH_AudioStreamBuilder* builder;
+OH_AudioStreamBuilder_Create(&builder, AUDIOSTREAM_TYPE_RERNDERER);
+```
+
+修改后
+
+```C
+OH_AudioStreamBuilder* builder;
+OH_AudioStreamBuilder_Create(&builder, AUDIOSTREAM_TYPE_RENDERER);
+```
+
