Airtime 1.9 on Lucid- worked before reboot, now no system sound- dummy output only

Hello,

I manually installed Airtime 1.9 on Lucid, and got everything to work fine. Then I changed passwords in icecast and broadcasting stopped. I realized that Ineed to change the password in liquidsoap, which i did. Now I get no errors from airtime-playout status, but there is no local system sound, and "On Air" is gray. tracks are playing, just no audio. I did not uninstall pulseaudio in my manual install.

below, [password] are all the same password.

airtime-playout status:
