**Description**  
After updating to use your major version 2 of the video sdk, we have 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

```kotlin
zoomSdk.testAudioDeviceHelper.startSpeakerTest()
zoomSdk.testAudioDeviceHelper.stopSpeakerTest()

```

Then it works for the second call, even though startSpeakerTest() returns internal error for both calls.

No exceptions are thrown and startAudio() returns Errors\_Success, but audio is completely silent.

**Which Android Video SDK version?**  
2.3.10

**To Reproduce(If applicable)**  
Happens every time we try to start a call.

**Screenshots**  
Not relevant

**Troubleshooting Routes**  
The troubleshooting attempt types you’ve already exhausted, including testing with the appropriate sample app (found on [Zoom · GitHub](https://github.com/zoom)).

**Smartphone (please complete the following information):**

- Device: Pixel 9
- OS: Android 16

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