Zoom Linux SDK audio recording not working
Hi Team, we are working on integrating our app with linux sdk and running into issues with accessing the zoom audio raw data
As per documentation, we have followed the below sequence of steps
1.Pre init- set the auth token,
2. implement an instance of the audio raw data callback ZoomSDKAudioRawDataDelegate
3. After recording privilege changed ->startRawRecording, getAudioRawDataHelperfor managing subscription and call subscribe event
Even though all the calls mentioned in the steps above result in ZoomSDKError_Success, the audio stream callbacks functions are never called. Log statements written within the functions onMixedAudioRawDataReceived and onOneWayAudioRawDataReceived never appear on the terminal.
Meanwhile the app works, we can interact with it, and perform all operations like join, leave, however the audio stream data is not there.
A few interesting logs we observed were
ALSA lib control.c:1379:(snd_ctl_open_noupdate) Invalid CTL
ALSA lib pcm.c:2642:(snd_pcm_open_noupdate) Unknown PCM
We are running the following experiment on linux centos amazon ec2 vm instance with latest linux SDK 5.15.12 . Note:this instance does not have any physical hardware sound drivers.We have installed the pulse audio setup on machine.
