Trixie Tricks

Are you struggling to navigate the new version of Raspberry Pi OS Trixie and its confusing sound interface choices? Look no further! I have developed a script that will make it super easy to manage sound interfaces for input and output.

How Does the Script Work?

By running the script on your Raspberry Pi, you will receive clear and concise recommendations for the best sound interfaces to use for both input and output. Say goodbye to confusion and hello to seamless sound management!

# Auto-detect CM108-like USB audio device and print WSJT-X settings.
#

set -e

# Find the first USB Audio capture device (CM108-style)
card_block=$(arecord -l 2>/dev/null | awk '
  /card [0-9]+:/ {line=$0}
  /USB Audio/    {print line ORS $0; exit}
')

if [ -z "$card_block" ]; then
  echo "No 'USB Audio' capture device found in arecord -l output."
  echo "Is the CM108 plugged in and recognized?"
  exit 1
fi

# Example line:
# card 2: Device [USB Audio Device], device 0: USB Audio [USB Audio]
card_num=$(grep -oE 'card [0-9]+' <<< "$card_block" | awk '{print $2}')
card_id=$(grep -oE 'card [0-9]+: [^ ]+' <<< "$card_block" | awk -F': ' '{print $2}')

out_sys="sysdefault:CARD=${card_id}"
out_sys=$(echo "$out_sys" | head -n 1)
out_plug="plughw:CARD=${card_id},DEV=0"
in_hw="hw:${card_num},0"
in_plug="plughw:CARD=${card_id},DEV=0"

echo "Detected USB audio capture device!"
echo
echo "Use this device in WSJT-X → Settings → Audio:"
echo "    ${out_sys}"
echo

Run The Script

Simply paste the contents above into a file called "toads-audio-helper.sh" and then run it with the command: "bash toads-audio-helper.sh"

You'll see output like on the screenshot above. Select that interface from the drop down and get back on the air!
