[URGENT] Regression: No audio on Android after upgrading to Video SDK 2.3.10

Description
After updating from 1.x.x to 2.3.10 of the video sdk, there are no longer any sound on our android app - iOS works fine, also when talking to the Android app.

We have however discovered that if we call

zoomSdk.testAudioDeviceHelper.startSpeakerTest()
zoomSdk.testAudioDeviceHelper.stopSpeakerTest()

Audio works after the second call, even though startSpeakerTest() returns an internal error on both attempts.
This suggests an audio routing/initialization issue fixed by the test helper rather than normal startAudio().

No exceptions are thrown and startAudio() returns Errors_Success, but there is no audio input/output on Android (complete silence).

Which Android Video SDK version?

us.zoom.videosdk:zoomvideosdk-core:2.3.10

To Reproduce(If applicable)
100% reproducible: Happens every time we start a call on Android after the upgrade.

Troubleshooting Routes

Testing with the sample app is not relevant since we only experience problems when also integrating with Android Telecom.

No crashes, no exceptions. Return codes appear successful despite silent audio.

Smartphone (please complete the following information):

Device: Pixel 9

OS: Android 16

Additional context
We are also using Android Telecom to manage calls.

Urgent request

Please confirm whether this is a known regression in 2.3.10 related to Android Telecom integration and advise on a hotfix or configuration workaround. If a fixed version exists, please provide the version number and any migration notes.

If useful, we can supply SDK logs at verbose level and additional AudioManager state to accelerate triage.
