I tried regular "play" (the one with sox). It worked and didn't give me the problem. Only aplay does that. I wonder if the ad1816a driver is really okay and it's just aplay that's wrong. > > Also, when I do "playmidi -e", it plays for the right length of time and > > gives no error messages, but produces no sound.

The status is not changed during playback and it still says Tx bytes :0.

Somehow, playmidi -e just started working right now, for no reason at all. I didn't do anything unusual. It continued working until I stopped Alsa and started it again, and then it stopped working again. I can't get it to work any more. When it was working the number in /proc/asound/card0/midi0 went up a lot. The number in /proc/interrupts didn't go up. I think that there are only supposed to be interrupts for input, not for output, so this is probably right. _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
