Hello, I would like to try the echo canceller webrtc in pulse audio. So I've install pulse audio with the webrtc aec enabled. And i've done an alsa configuration file like this : pcm.pulse { type pulse} ctl.pulse { type pulse} pcm.!default { type pulse} ctl.!default { type pulse} The first problem is my record device is on the card 1. And it seems (when i'm doing parecord and "pactl info" => Default Source: alsa_input.0.analog-stereo) it records on the sound card 0. The second problem is, is there any option to enabled the echo canceller ? Or I just have to do : paplay random_file.wav & parecord > record To have a record file without the random_file.wav sound. Thanks in advance for your help. -------------- next part -------------- An HTML attachment was scrubbed...
