Hi,

The librespeaker examples shows the Aloop function. Trying to record, process and playback using this example with 'arecord -Dhw:Loopback,1,0 -c 1 -r 16000 -f S16_LE | aplay -Dhw:0,1 -c 1 -r 16000' didn't work. Any suggestions? The aplay part seems to work only for 2 channel outputs, but changing the channel setups didn't work.

Thanks in advance!
