Audio issues in safari browser in MacOS

[Surendhar95]

Describe the bug

I'm currently experiencing the following audio issues in a group video call when joined using Safari browser in MacOS:

• Not able to hear audio of remote audiences sometimes in the channel (this is happening only in safari version 13.x).
• There is also echo in the channel when an user join from safari with headset connected. This works perfectly fine in other browsers - Chrome and Firefox.

SDK Logs

No error is thrown for these issues.

Platform and Browser:

MacOS 10.15.5
Safari 13.1.1

SDK Version:

"agora-rtc-sdk-ng": "^4.3.0",

To Reproduce

Steps to reproduce the behavior:

1. Join a channel for a video call in safari v13.x
2. Use a headphone for audio and publish the track in the channel with other users
3. Other users in the channel must be hearing echo when any participant talks.
4. Also if a remote client has published audio track and they talk something, it can't be heard in safari.

Additional context

The echo behaviour is only happening when a client joins using headphone, it doesn't happen otherwise.

Also when the remote audio track is played using remoteAudioTrack.play() agora returns no error but still no audio can be heard in safari v13.x.

Agora has mentioned that the new SDK (agora-rtc-sdk-ng) doesn't completely support Safari but it would be really helpful to know if these issues are consistent with the already observed behaviour in safari.

Thanks

could you pls provide a channel which you used to reproduce the channel? ideally a unique channel name would be helpful. i can help check out the backend quality data.
