Thanks for the idea George. I tried using dmix with the instructions in the link that you provided above but it instructs to create a .pa file in the directory: /etc/pulse/default.pa.d/ but this is a directory that does not exist on the RPI. I have tried appending the lines:
unload-module module-udev-detect unload-module module-detect load-module module-alsa-sink device=dmix load-module module-alsa-source device=dsnoop to my /etc/pulse/default.pa but that causes aplay to give a busy error: aplay: main:830: audio open error: Device or resource busy and Moode to also still give one as well.
