Does Chime support sharing audio during screen sharing?

Yes, Amazon Chime SDK does support sharing audio during screen sharing, but there are important limitations to be aware of based on your platform.

For the Amazon Chime SDK Android client library, there is a significant constraint: it only supports content share from screen capture itself, not audio from other sources. The Android SDK supports sending mono audio up to 48kHz at 64kbps and receiving stereo audio at 48kHz, but this applies to microphone audio in the meeting, not audio from the content being shared.

When sharing content (including screen sharing), the Amazon Chime SDK sessions do support content audio that can be mixed into the audio stream. Content audio supports sample rates up to 48kHz and up to 2 channels (stereo) encoded with bitrates up to 128kbps using the Opus codec. However, the ability to capture and share this audio alongside your screen content depends on the capabilities of the specific client library you're using.

Since you're using the Android SDK and cannot use the JavaScript SDK, you're limited by the Android library's capabilities, which currently only support screen capture for content sharing without the ability to capture system audio or audio from other applications during screen sharing. The JavaScript and React libraries have broader support for content sharing from various sources, but those options are not available to you given your project constraints.
