I just picked up a Funcube Dongle, its a USB audio device with a fixed
sample rate of 96000. Im getting errors though when trying to access it
using audio source, I set the samp_rate to 96000 but am getting errors
AudioUnitRender
Error# -10863 ('AudioUnitRender
Error# -10863 ('
osx/audio_osx_source.cc:791
Ive noticed that I can use the LineIn upto 44100 (using Audio MIDI Setup)
then I get the same errors, the FCD has a fixed sample rate so I dont have
the option of using something smaller. Setting the sample rate in gnuradio
doesnt seem to set the sample rate of the input as I would have thought, it
just needs to be set to match whatever the input is currently set to
already.
I know the device is working fine in OSX as I can use audacity to record a
sample and save to WAV, then use a WAV source in gnuradio to playback the
sample without issue.
Im using the latest git master branch of gnuradio. Im using 10.6.7 on my
macbook.
