I don't think the tool can be made to work in real time. ALSA's a52 plugin uses ffmpeg's libavcodec to convert 6-channel PCM to AC-3. It works more or less transparently for ALSA applications; it would not be easy to convert it to an API that does not have support for userspace plugins. Best regards, Clemenshelp
