I should check if the card-flash image for 11.04 still around somewhere. > FWIW, I don't recommend using alsa on pandaboard/ubuntu.

As I have plans to change the code to allow it to work without sound libraries (which would make it easier to compile on windows), so -why not- add an option to use pulseaudio. OK, something for on my "to do" list. :-) > My goal is to pair the pandaboard with an FT-817, then use my TS-2000 > to beacon Codec2 modulated with your modems.

Perhaps, even more fun, a cross mode parrot: FM to codec2 and the other way around. Hmm. This would require a merge of the gmsk modem and the wav-modem I also have (pre-pre-pre alpha code). OK. I'll put that on the "crazy idea" list for the time being. :-) > 73, Bruce 73 Kristoff - ON1ARF ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
