+```
+
+**适配指导**
+
+对于OH_AudioStreamBuilder_SetRendererInfo接口，开发者按照所属场景，原本设置的OH_AudioStream_Content类型可对比下表，使用对应的OH_AudioStream_Usage类型。
+
+| OH_AudioStream_Content          | OH_AudioStream_Usage                  |
+| ------------------------------- | ------------------------------------- |

+| AUDIOSTREAM_CONTENT_TYPE_MOVIE  | AUDIOSTREAM_USAGE_MOVIE               |
+
+对于OH_AudioRenderer_GetRendererInfo接口，开发者使用新的接口只能获取到OH_AudioStream_Usage属性，不能获取OH_AudioStream_Content属性。
+
+## cl.multimedia.3 OH_AudioStream_Usage变更
+
+API10的音频C接口native_audiostream_base.h 文件中，在OH_AudioStream_Usage枚举中删除了AUDIOSTREAM_USAGE_MEDIA枚举值，将AUDIOSTREAM_USAGE_COMMUNICATION枚举值变更为AUDIOSTREAM_USAGE_VOICE_COMMUNICATION和AUDIOSTREAM_USAGE_VOICE_ASSISTANT。
+
+**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。如果开发者使用AUDIOSTREAM_USAGE_MEDIA和AUDIOSTREAM_USAGE_COMMUNICATION枚举值，会有兼容性问题。

+    /**
+     * Movie or video usage.

+    AUDIOSTREAM_USAGE_MOVIE = 10,
+
+} OH_AudioStream_Usage;
+```
+
+**适配指导**
+
+用户通过OH_AudioStreamBuilder_SetRendererInfo接口不能再设置OH_AudioStream_Usage值为AUDIOSTREAM_USAGE_MEDIA，改为使用AUDIOSTREAM_USAGE_MUSIC或者AUDIOSTREAM_USAGE_MOVIE。
+
+修改前
+
+```C

+
+修改后

+
+或者
+
+```C
+OH_AudioStreamBuilder_SetRendererInfo(builder, AUDIOSTREAM_USAGE_MOVIE); // 视频场景
+```
+
+用户通过OH_AudioStreamBuilder_SetRendererInfo接口不能再设置OH_AudioStream_Usage值为AUDIOSTREAM_USAGE_COMMUNICATION，改为使用AUDIOSTREAM_USAGE_VOICE_COMMUNICATION或者AUDIOSTREAM_USAGE_VOICE_ASSISTANT。

+## cl.multimedia.4 OH_AudioStream_SampleFormat变更，删除AUDIOSTREAM_SAMPLE_F32LE
