ALSA “dmix plugin supports only playback stream” error when using dmix on beagleboard
On a Beagleboard, I need it to play sound from several processes.
The default /etc/asound.conf is empty, so I put this dmix example in.
Now sund mixes fine, but when I'm trying to run a process that uses a microphone, I'm getting "(snd_pcm_dmix_open) The dmix plugin supports only playback stream".
What do I fix in the configuration to make software mixing and microphone work?

Maybe I wasn't clear - I don't need to mix a microphone signal, I only want it to work. Currently, it doesn't, at least for some programs.

The dmix plugin works only for playback devices.
To be able to have a device that uses dmix for playback and does something else for capturing, you have to use the asym plugin to define different plugins for playback/capture.
