Hi all. My original aim is to run "Import Audio" in audacity; on ARM architecture. However, the error messages that appear seem to be related to portaudio. As part of my efforts, a) I downloaded and built "Portaudio" on ARM, from http://www.portaudio.com/archives/pa_stable_v19_20111121.tgz. b) I then ran "./configure --with-alsa" "make" "sudo make install" c) "/bin/pa_devs" gave the output ###################################################################################################### ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown

So, I will be grateful, if someone could please let me know as to which part should I investigate into :: portaudio, or alsa. Will be grateful for a reply.
