So, I guess multi-playing won't workwithout DSP codes. You can use dmix instead. At least, there is one positive report :)For testing, just run like % aplay -Dplug:dmix foo.wav Takashi_______________________________________________Alsa-devel mailing listAlsa-devel@xxxxxxxxxxxxxxxxxxxx://mailman.alsa-project.org/mailman/listinfo/alsa-devel
