Invalid Buffer size

Describe the bug

I have 2 applications one is the pubblish and the other is just the client. When I connect to stream in client i recive this:

FATAL EXCEPTION: com.haishinkit.codec.AudioCodec
Process: com.audioguiame.guidum, PID: 19985
java.lang.IllegalArgumentException: Invalid audio buffer size.

at android.os.HandlerThread.run(HandlerThread.java:65)

We have this application in ios and is working well "pubblish" (ios, android) to ios client but with android receiving that.

To Reproduce

1. Pubblish a stream
2. Connect with Android client
3. Crash with codec

Expected behavior

Also i can see this: sampleRate=44100, channelCount=1, bufferSize=-2

[shogo4405]

• bufferSize=-2 means AudioTrack.ERROR_BAD_VALUE.
  How can I reproduce it? I would like to know the device name and the version of Android you are using.

Hi @shogo4405,

Thanks for your response!
It happens with any android I tried with: Xiaomi Mi8 (Android 11), Xiaomi Redmi note 11 pro (Android 12) Redmi 8 (Android 10), Pixel Api 28, and pixel api 33.
If i emit from ios i get the samee error sampleRate=48000, channelCount=1, bufferSize=-2. If I emit from Android sampleRate=44100, channelCount=1, bufferSize=-2.
At the moment we solved in our server changing de codec and transforming in other pathe like /android/"code".
If i can help just tell me.
