**Description** I have been using the samples from here - [GitHub - tanchunsiong/MSDK\_RawDataDemos at 50f292d5cc859d9931a084b67fff912a964e7d8f](https://github.com/tanchunsiong/MSDK_RawDataDemos/tree/50f292d5cc859d9931a084b67fff912a964e7d8f) I have the video and screenshare working as soon as my bot joins the call, however, I am running into issues with audio - it only seems to work when the unmute button is pressed, is there a way to get the audio to play as soon as the bot joins? When I update the code to allow the bot to join with audio on, it still only seems to play the audio when I mute and then unmute the bot. I noticed this //TODO comment in the code and was wondering if there is a code snippet that could solve this - [https://github.com/tanchunsiong/MSDK\_RawDataDemos/blob/50f292d5cc859d9931a084b67fff912a964e7d8f/SendAudioRawData/MSDK\_SendAudioRawData.cpp#L61-L78](https://github.com/tanchunsiong/MSDK_RawDataDemos/blob/50f292d5cc859d9931a084b67fff912a964e7d8f/SendAudioRawData/MSDK_SendAudioRawData.cpp#L61-L78) Thanks, Chloe ---

I’m not sure if this pop up could be causing the error: ![Screenshot 2023-12-06 at 11.08.09](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/3/a/3a59e899c8c7116930803de20a64773aa4225297.png) When I close this pop-up I can see the virtual mic is set and it is unmuted: ![Screenshot 2023-12-06 at 11.08.31](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/b/0/b0143c813a13567dd0221488eed3d48f289bfc2d.png) But the audio will only play on the call, when I hit the microphone to mute it and then press it again to unmute - on this second press the audio plays as expected. I can see the onMicInitialize is called, but it looks like onMicStartSend only gets triggered when I unmute the bot. The goal is to get the bot to play the audio as soon as it joins the call. ---

@chunsiong.zoom have you got any advice on if this is possible or how to solve it? ---

@chloe3 I don’t have a best practice for this yet, however for testing / sample purposes I unmute my audio when I receive a specific message event. ---

@chunsiong.zoom thanks for your response, have you got an example of unmuting when you receive a specific message event? ---
