Thanks for the ideas! The wire in the joystick port was awesome. Answers inline...

That's silly... OHMYGOD. Yup, whatever I write out to /proc/asound/dev/midiC0D0 is echoed back when I have pins 12 and 15 connected. If I remove the wire, I see nothing echoed back. [ more screaming deleted ] So I'm guessing that, in fact, I have a bad cable. It explains why various kernel and driver recompiles over the past two weeks made no difference. [ more screaming deleted ] I will get a better cable tomorrow. And write a short letter to my old cable's manufacturer. Thanks for the help! I'm excited to be moving forward on my project again. -Thomas ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
