Description
Audio out of sync in teams Recording Bot
When the call has more than 2 participants, the mixed audio, prefixed with "_all" gets out of sync and the voices of the participants stay like a slow motion audio. The application runs like a charm. The problem only happens with the mixed audio. The unmixed audios stay in high quality. If I setup the flag "ReceiveUnmixedMeetingAudio" to false in "BotService" class, the problem does not happen. I have executed the sample in Visual Studio 2019, in a local container with wsl2 and in Azure aks and I have got the same result.
I am using the branch master of the repository.
Thanks in advance,
Victor.

Research direction
Start in the BotService class and trace the ReceiveUnmixedMeetingAudio setting and the mixed audio prefixed with "_all". Reproduce a call with more than two participants in the reported environments, comparing mixed and unmixed recordings. Done means mixed audio stays synchronized and at normal speed while ReceiveUnmixedMeetingAudio remains enabled.
