Thanks for all. I can fix it changing the driver from alsa to oss.

Thanks, I use "sudo modprobe snd-seq".Now it shows an different error: "Looking for tentacle Trying to start game 'Day of the Tentacle' WARNING: Could not open audio device: No available audio device! WARNING: Sound mixer initialization failed ! Can't subscribe to MIDI port (65:0) see...

It shows this: Looking for tentacle Trying to start game 'Day of the Tentacle' WARNING: Could not open audio device: No available audio device! WARNING: Sound mixer initialization failed !

I'm trying to play sounds in Day of Tentacle, in Debian, but i choose the ALSA driver and the program closes when I try to play game.
Any idea, please?
Thanks
