Seems like that GitHub sample is returning 404 so it was likely removed or renamed by Zoom. Rather than chasing that link, here’s the high-level path to **real-time raw audio** on Linux:

- Set up the Linux Meeting SDK and [enable raw-data features (guide)](https://developers.zoom.us/docs/meeting-sdk/linux/add-features/raw-data/)
- Implement the audio callbacks via [`IZoomSDKAudioRawDataDelegate`](https://marketplacefront.zoom.us/sdk/meeting/linux/class_i_zoom_s_d_k_audio_raw_data_delegate.html) (e.g., mixed or one-way audio).
- Subscribe/unsubscribe using [`IZoomSDKAudioRawDataHelper::subscribe(...)`](https://marketplacefront.zoom.us/sdk/meeting/linux/class_i_zoom_s_d_k_audio_raw_data_helper.html).
- Consume PCM frames from [`AudioRawData`](https://marketplacefront.zoom.us/sdk/meeting/linux/class_audio_raw_data.html) and forward them to your processing/streaming pipeline.

This flow - SDK init → delegate → subscribe → consume PCM - covers the core pieces without relying on any specific sample repo
