WM5102 Acoustic Echo Cancellation

I have wolfson audio card with raspberry pi module. I am able to stream audio over the network, but I am hearing my own voice in the speaker. I am using g-streamer library.

Can I use WM5102 with Acoustic echo cancellation? If yes please let me know how to use it?

Also about configuring DSP firmware with Wolfson-supplied software packages.

Can anyone please guide me with this?

Thanks

Does this have anything to do with the built in mic?

Is this classic Echo Cancellation or are you actually picking up your voice again legitimately through the speaker as you speak causing the feed back. You may be able to try moving the mic closer to the subject or have a separate mic to pick up ambient noise etc so you can reject it. The only other immediate advice is to see how the Telco software like asterisk manage it since they do this in S/W.

Thanks for your reply.

I am using headset with mic. Actually it is picking our own voice again and playing in our own speaker. According to the WM5102 audio codec and echo cancellation manual, the acoustic echo cancellation bit can be enabled. For that we need to use DSP firmware. Where we can get suitable DSP firmware and how to write code for DSP?
