Low Audio Volume Using Meeting SDK

[espresso]

We are using the iOS Meeting SDK version 5.16.6 and are experiencing low audio volume in our apps on iPhones even when the device's audio volume is turned up to the maximum.

We couldn't find anything related to volume configuration in the SDK docs. What could be the issue?

Seems like we were using the wrong audio source.

I saw there is an option to switch the audio source but I haven't seen any possibility for choosing a specific audio source, like the loud speaker. Is there no method for this?
