hey guys im getting an error when trying to use a USB mic with portaudio.
wondering if anyone could help me solve this problem.
im using ubuntu intrepid studio. portaudio is loaded correctly and sees the
all the devices. when i do a "pa call" using the built in sound card, i am
able to connect to the call. but when i set the "pa indev #7" (#7 is the USB
mic) and then do a "pa call" i get the following error

>pa call 4800
2009-01-28 12:33:09 [NOTICE] switch_channel.c:566 switch_channel_set_name()

here is the output from "pa devlist"

7;Samson C01U              : USB Audio (hw:1,0);2;0;i

any input would be much appreciated. thanks again for developing such a fine
piece of software!
