从log分析, 音乐停止主要还是systemui 发送了消息, 获取到了音频焦点,
导致播放的音乐暂停了.

具体的log如下:

12-31 04:47:27.713  1488  6150 I MediaFocusControl: requestAudioFocus() from uid/pid 10089/7461 AA=USAGE_MEDIA/CONTENT_TYPE_MUSIC clientId=android.media.AudioManager@218de0dcom.android.music.MediaPlaybackService$4@34cb1c2 callingPack=com.android.music req=1 flags=0x0 sdk=31

12-31 04:48:57.875   805  4540 D audio_hw_primary: start_output_stream: exit
12-31 04:48:57.971  1488  4658 I MediaFocusControl: requestAudioFocus() from uid/pid 10081/1954 AA=USAGE_NOTIFICATION/CONTENT_TYPE_SONIFICATION clientId=android.media.AudioManager@e95a65d callingPack=com.android.systemui req=3 flags=0x0 sdk=31

但既然systmeui 发送了消息, 那么会听到一个消息音才对.
正在和测试小伙伴确认进一步的信息.

如果是音乐暂停, 当消息未响起, 那还需要从audio侧研究下, 是否为正常的设计.

多谢!

从log进行分析, 应该是driver堵塞住了.
需要audio bsp查看下堵塞的原因.

具体的log:

12-31 04:47:27.713  1488  6150 I MediaFocusControl: requestAudioFocus() from uid/pid 10089/7461 AA=USAGE_MEDIA/CONTENT_TYPE_MUSIC clientId=android.media.AudioManager@218de0dcom.android.music.MediaPlaybackService$4@34cb1c2 callingPack=com.android.music req=1 flags=0x0 sdk=31
12-31 04:47:28.141   805  8051 D audio_hw_primary: No space available in compress driver, post msg to cb thread
12-31 04:47:28.800   805  8051 D audio_hw_primary: No space available in compress driver, post msg to cb thread
12-31 04:47:29.607   805  8051 D audio_hw_primary: No space available in compress driver, post msg to cb thread

堵住的原因很大可能和下边的log相关:

12-31 04:45:48.989   805  1718 D audio_hw_primary: adev_set_parameters: enter: reconfigA2dp=true
12-31 04:45:48.989   805  1718 D audio_hw_primary: reconfigure a2dp... forcing device switch
12-31 04:45:48.989   805  1718 D audio_hw_primary: Switching to speaker and muting the stream before select_devices

这个log产生的原因主要是蓝牙模块频繁调用audio接口setParameter接口(reconfigA2dp=true).
因为需要重新配置a2dp, 会强制切换speaker, 但由于没有中控, 导致数据传输堵塞, 无法进行下一步操作, 蓝牙无法接收到数据. <-麻烦看下是否是此原因导致.

多谢!
