Audio_Sample_Rate is not aligned between spec and real life

Realtime Media Streams

Hello,
Iam doing RTMS for ZCC, about the audio sample rate, we have this from the spec, which would be applied for raw L16 audio
enum AUDIO_SAMPLE_RATE
{
SR_8K = 0,
SR_16K = 1,
SR_32K = 2,
SR_48K = 3
}

However, in reality, 8000Hz is not available, only from 16000Hz, and it is 0 instead, and 1 and 2 for 32K and 48K respectively
This is observed from Data Hanshake Response from the server, i.e if it says "sample_rate": 0 then the audio it sends is 16K

Please confirm if this is know issue and would it be keep this way, otherwise future fix will break all existing implementation
Thanks

Hi @MinhCm,

Thank you for bringing this up. I will attempt to verify what you’re seeing on my end and share with the engineering team. I’ll share any relevant updates with you in this thread.

Best,
