You are likely connecting to an RTSP camera that is using either µ-law or a-law audio. You will need to use Wowza Streaming Engine’s Transcoder to convert the audio channel to AAC for your clients to have audio. Below is the article on how to do this. [https://www.wowza.com/docs/how-to-transcode-only-the-audio-channel-of-an-incoming-stream](https://www.wowza.com/docs/how-to-transcode-only-the-audio-channel-of-an-incoming-stream) ---

Is this after you transcoded the audio to AAC? Still not working? If so, please submit a support ticket so we can test why this is happening. Thanks you. [https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket) ---

Hello @Hüseyin Ergen. I checked your support tickets and they are responding to your email address that you are using. The pima.com.tr email address. Have you searched your email folders? There have been two responses for two tickets and they are waiting to hear back from you. It may be in your spam? Can you search Wowza in your email? ---

We do occasionally see an issue with responses from our ticketing system falling into customer spam/junk folders. Please ensure you have whitelisted the email address “[tickets@wowzamedia.com](mailto:tickets@wowzamedia.com)” in your email account or system to avoid further delay in receiving our responses. Additionally, you can search for key words like Wowza, Streaming Engine, Wowza Sales, etc in the subject header of your email. ---
