Unable to define mic #2

Closed davidw38 closed 5 years ago

davidw38 commented 5 years ago

Hey, i wanted to try this echo canceller but when I try to start the program with the following: ./ec -i plughw:0 -o plughw:1 -d 200 I am getting this error: Running... Press Ctrl+C to exit ec: src/audio.c:62: set_params: Assertion `err >= 0' failed.

If I try starting ec using: ./ec -i plughw:1 -o plughw:1 -d 200 ec starts but the input does not work because my mic is at slot "0" and not slot "1"

How to fix this?

Which sound card do you use?

Maybe the sound card doesn't support setting buffer size. You can try to comment the line https://github.com/voice-engine/ec/blob/master/src/audio.c#L61
