# Run a loopback test in the background after a delay.
# To run the script, enter these commands once:
#    adb disable-verity
#    adb reboot
#    adb remount
#    adb sync
#    adb push loopback.sh /data/
# For each test run:
#    adb shell "nohup sh /data/loopback.sh &"
# Quickly connect USB audio if needed, either manually or via Tigertail switch.
# Wait until the test completes, restore USB to host if needed, and then:
#    adb pull /data/loopreport.txt
#    adb pull /data/loopback_all.wav
#    adb pull /data/loopback_echos.wav
