I have Campcaster 1.4 installed on Ubuntu Hardy server (no gnome, no CC studio)
After making and scheduling a playlist (all ogg, or all mp3, not mixed as per Doug's previous bug report), it plays the first song then silence. The Javascript box in the header shows the next song playing but there is no sound.
Note: I had this same effect before realizing that my firewall was blocking port 3344 and it wouldn't play any sound at all. Then after fixing the firewall it plays the first song, then nothing. Thinking it's still a firewall problem i've flushed the iptables ( iptables -F ) but still no joy.
