Greetings Yanbin Z，

I use two android device, device A is my custom device with the sound card info below：

root@tulip-d1:/ # cat /proc/asound/pcm
00-00: SUNXI-CODEC codec-aif1-0 :  : playback 1 : capture 1
00-01: bb Voice codec-aif2-1 :  : playback 1 : capture 1
00-02: bb-bt-clk codec-aif2-2 :  : playback 1 : capture 1
00-03: bt Voice codec-aif3-3 :  : playback 1 : capture 1

And device B is a mobile phone make by Huawei.

In my test, two device joined in the same room. Device A just subsribe remote stream, and didnot publish stream.And device B publish local stream, device A got Noise all the time even if device B is disable local audio.

By the way, I have played music or other voice call on device A, it didn't show noise.

Thank you!

In the v 3.5 SDK, I can't get raw audio data (uncompressed PCM audio data) of a remote media stream, if I can do that, I will save the audio data for some more detail analyze to check whether is the data is error or my media decoder is error.

Hi,how's the progress?

Thanks!

[He_Z_Intel]

Hi Lee

Did device A subscribe a RemoteMixedStream or a RemoteCameraStream published by device B?

How did you disable device B local audio?  And were there any other streams published in the same room?

Hi Hank Zhang

Device A just subscribe a RemoteMixedStream. I used the api "LocalCameraStream.disableAudio()" on device B. And there are just two device in the meeting.
