Thank you for your reply. Unfortunately, you've told nothing new for me. After all, I am Linux user and administrator since early 1996 ... My user account has write permission to /dev/dsp, and /dev/dsp is not blocked by any other process. Artsd is running, but it is configured to auto-suspend after 1 second of idle. I can start different programs that do use sound, and they work perfectly. I even can start aviplay with other movies, and sound is OK. In this case, something specific is happening, and I can't find out what exactly. Maybe it is "nChannels=3" in the above log: perhaps it wants more output channels that my audiocard supports? I don't know much about digital audio. Other guess is about artsd. My libsdl is libsdl1.2debian-arts, so when aviplay uses SDL driver, it should output to artsd (and it does when playing other movies). Maybe artsd can't handle nChannels=3? What is AC3 audio format, after all? Can it be played on a cheap audio card?
