Hi,
When I connect a USB soundcard to my Raspberry PI and run alsaloop (a utility to play back the sound that is currently being received by the soundcard) the sound is very choppy (whether I play it back through HDMI or the same USB card). If I simply record the input with arecord and play it back later, there is no choppiness. It seems RPi can't cope with both audio input and output simultaneously. Is there a way to fix this?
Thanks.

Re: USB audio issues
I have had issues with different sample rates and resolved it by hard setting all programs to 48000.
Try the following, it works for me. (According to my notes)
Not familiar with aslaloop, will give it a go tomorrow.

Code: Select all
arecord -D hw:1,0 -c 2 -r 48000 -f dat | aplay -f dat
