Raspberry ALSA sound output / input slave

Question

I\'m trying to set one device for playback and another one for capture, my nano /etc/asound.conf has this:

pcm.!default {
        type asym
             


        

Answer 1

pyaudio is based on PortAudio; all those silly messages are because of PortAudio's attempts to enumerate audio devices.

pyaudio device indexes are not necessarily the same as ALSA card indexes. Use get_device_count() and get_device_info_by_index() to find the input device to use.
