5.<\/b><\/span>\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/span>SSH in:<\/span><\/p>

\u00a0<\/span><\/p>

\u00a0<\/span><\/p>

\"\u2139\" NOTE\u00a0\u00a0<\/span><\/b><\/span>If airplay.local doesn’t resolve, find the Pi’s IP in your router’s DHCP table and use that directly.<\/span><\/p><\/div>

Step 2 \u2014 System Update & Dependencies<\/b><\/span><\/p><\/div>

\u00a0<\/span><\/p>

sudo apt update && sudo apt upgrade -y<\/span><\/p>

\u00a0<\/span><\/p>

sudo apt install -y \\<\/span><\/p>

\u00a0 shairport-sync \\<\/span><\/p>

\u00a0 alsa-utils \\<\/span><\/p>

\u00a0 avahi-daemon \\<\/span><\/p>

\u00a0 usbutils \\<\/span><\/p>

\u00a0 evtest \\<\/span><\/p>

\u00a0 sox \\<\/span><\/p>

\u00a0 git<\/span><\/p>

\u00a0<\/span><\/p>

Step 3 \u2014 Connect & Identify the BeoPlay A8<\/b><\/span><\/p><\/div>

Plug the BeoPlay A8 into the Pi via USB, then verify it is detected:<\/span><\/p>

\u00a0<\/span><\/p>

aplay -l<\/span><\/p>

\u00a0<\/span><\/p>

You should see an entry like:<\/span><\/p>

\u00a0<\/span><\/p>

card 0: Speaker [B&O Speaker], device 0: USB Audio [USB Audio]<\/span><\/p>

\u00a0<\/span><\/p>

\"\u26a0\" IMPORTANT\u00a0\u00a0<\/span><\/b><\/span>The card name is Speaker and the ALSA card number is 0. We will always reference it by name (Speaker) throughout this guide to avoid problems if the number changes after a reboot.<\/span><\/p><\/div>

Confirm the USB port path (needed for wake\/sleep scripts):<\/span><\/p>

\u00a0<\/span><\/p>

dmesg | grep -i “beoplay\\|B&O\\|bang” | tail -10<\/span><\/p>

\u00a0<\/span><\/p>

Look for a line like:<\/span><\/p>

\u00a0<\/span><\/p>

usb 1-1: Product: B&O Speaker<\/span><\/p>

\u00a0<\/span><\/p>

The port path is 1-1. Note this \u2014 you will use it in Steps 7 and 8.<\/span><\/p>

Step 4 \u2014 Configure ALSA<\/b><\/span><\/p><\/div>

Create the ALSA configuration file that defines the softvol layer on top of the A8’s USB DAC. This is what enables iPhone volume control.<\/span><\/p>

\u00a0<\/span><\/p>

sudo nano \/etc\/asound.conf<\/span><\/p>

\u00a0<\/span><\/p>

Paste the following (exactly as shown \u2014 card name Speaker, not a number):<\/span><\/p>

\u00a0<\/span><\/p>

pcm.beoplay_hw {<\/span><\/p>

\u00a0\u00a0\u00a0 type hw<\/span><\/p>

\u00a0\u00a0\u00a0 card Speaker<\/span><\/p>

\u00a0\u00a0\u00a0 device 0<\/span><\/p>

}<\/span><\/p>

\u00a0<\/span><\/p>

pcm.beoplay_softvol {<\/span><\/p>

\u00a0\u00a0\u00a0 type softvol<\/span><\/p>

\u00a0\u00a0\u00a0 slave.pcm “beoplay_hw”<\/span><\/p>

\u00a0\u00a0\u00a0 control {<\/span><\/p>

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 name “SoftMaster”<\/span><\/p>

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 card Speaker<\/span><\/p>

\u00a0\u00a0\u00a0 }<\/span><\/p>

\u00a0\u00a0\u00a0 min_dB -60.0<\/span><\/p>

\u00a0\u00a0\u00a0 max_dB 0.0<\/span><\/p>

\u00a0\u00a0\u00a0 resolution 100<\/span><\/p>

}<\/span><\/p>

\u00a0<\/span><\/p>

pcm.!default {<\/span><\/p>

\u00a0\u00a0\u00a0 type plug<\/span><\/p>

\u00a0\u00a0\u00a0 slave.pcm “beoplay_softvol”<\/span><\/p>

}<\/span><\/p>

\u00a0<\/span><\/p>

ctl.!default {<\/span><\/p>

\u00a0\u00a0\u00a0 type hw<\/span><\/p>

\u00a0\u00a0\u00a0 card Speaker<\/span><\/p>

}<\/span><\/p>

\u00a0<\/span><\/p>

Initialise the SoftMaster control (ALSA only creates it after first use):<\/span><\/p>

\u00a0<\/span><\/p>

speaker-test -c 2 -t sine -f 440 -D beoplay_softvol &<\/span><\/p>

sleep 3<\/span><\/p>

kill %1<\/span><\/p>

amixer -c Speaker sset SoftMaster 100%<\/span><\/p>

sudo alsactl store<\/span><\/p>

sudo systemctl enable alsa-restore<\/span><\/p>

\u00a0<\/span><\/p>

Verify the control exists:<\/span><\/p>

\u00a0<\/span><\/p>

amixer -c Speaker sget SoftMaster<\/span><\/p>

\u00a0<\/span><\/p>

You should see: Limits: Playback -6000 – 0<\/span><\/p>

Step 5 \u2014 Configure Shairport-Sync<\/b><\/span><\/p><\/div>

\u00a0<\/span><\/p>

sudo nano \/etc\/shairport-sync.conf<\/span><\/p>

\u00a0<\/span><\/p>

Replace the entire file with:<\/span><\/p>

\u00a0<\/span><\/p>

general = {<\/span><\/p>

\u00a0\u00a0\u00a0 name = “BeoPlay A8”;<\/span><\/p>

\u00a0\u00a0\u00a0 volume_range_db = 60;<\/span><\/p>

};<\/span><\/p>

\u00a0<\/span><\/p>

alsa = {<\/span><\/p>

\u00a0\u00a0\u00a0 output_device = “default”;<\/span><\/p>

\u00a0\u00a0\u00a0 mixer_control_name = “SoftMaster”;<\/span><\/p>

\u00a0\u00a0\u00a0 mixer_device = “hw:Speaker”;<\/span><\/p>

};<\/span><\/p>

\u00a0<\/span><\/p>

sessioncontrol = {<\/span><\/p>

\u00a0\u00a0\u00a0 run_this_before_play_begins = “\/usr\/local\/bin\/beoplay-wake.sh”;<\/span><\/p>

\u00a0\u00a0\u00a0 run_this_after_play_ends = “\/usr\/local\/bin\/beoplay-sleep.sh”;<\/span><\/p>

\u00a0\u00a0\u00a0 wait_for_completion = “yes”;<\/span><\/p>

};<\/span><\/p>

\u00a0<\/span><\/p>

\"\u26a0\" IMPORTANT\u00a0\u00a0<\/span><\/b><\/span>The sessioncontrol block is critical \u2014 it triggers wake\/sleep on AirPlay session events. Any syntax error (missing semicolon, wrong quote type) silently disables it.<\/span><\/p><\/div>

Step 6 \u2014 Create Jingle Sound Files<\/b><\/span><\/p><\/div>

Generate short tones that play when the A8 wakes up and before it sleeps:<\/span><\/p>

\u00a0<\/span><\/p>

# Wake jingle \u2014 two ascending tones<\/span><\/p>

sox -n \/usr\/local\/share\/beoplay-wake.wav synth 0.15 sine 880 synth 0.15 sine 1100 : synth 0.15 sine 880 synth 0.15 sine 1100<\/span><\/p>

\u00a0<\/span><\/p>

# Sleep jingle \u2014 two descending tones<\/span><\/p>

sox -n \/usr\/local\/share\/beoplay-sleep.wav synth 0.15 sine 1100 synth 0.15 sine 880 : synth 0.15 sine 1100 synth 0.15 sine 880<\/span><\/p>

\u00a0<\/span><\/p>

Test them:<\/span><\/p>

\u00a0<\/span><\/p>

aplay -D default \/usr\/local\/share\/beoplay-wake.wav<\/span><\/p>

aplay -D default \/usr\/local\/share\/beoplay-sleep.wav<\/span><\/p>

\u00a0<\/span><\/p>

Step 7 \u2014 Create the Wake Script<\/b><\/span><\/p><\/div>

This script binds the A8’s USB port (powering it on), waits for the DAC to initialise, then plays the wake jingle. Replace 1-1 with your USB port path from Step 3.<\/span><\/p>

\u00a0<\/span><\/p>

sudo bash -c ‘cat > \/usr\/local\/bin\/beoplay-wake.sh << EOF<\/span><\/p>

#!\/bin\/bash<\/span><\/p>

echo “1-1” > \/sys\/bus\/usb\/drivers\/usb\/bind<\/span><\/p>

sleep 6<\/span><\/p>

aplay -q -D default \/usr\/local\/share\/beoplay-wake.wav<\/span><\/p>

EOF’<\/span><\/p>

\u00a0<\/span><\/p>

sudo chmod +x \/usr\/local\/bin\/beoplay-wake.sh<\/span><\/p>

\u00a0<\/span><\/p>

\"\u26a0\" IMPORTANT\u00a0\u00a0<\/span><\/b><\/span>The 6-second sleep is essential. The A8’s USB DAC needs time to fully initialise after bind \u2014 too short and shairport-sync crashes trying to open the audio device.<\/span><\/p><\/div>

Step 8 \u2014 Create the Sleep Script<\/b><\/span><\/p><\/div>

This script waits 30 seconds for an idle grace period, plays the sleep jingle, then unbinds the USB port putting the A8 into standby.<\/span><\/p>

\u00a0<\/span><\/p>

sudo bash -c ‘cat > \/usr\/local\/bin\/beoplay-sleep.sh << EOF<\/span><\/p>

#!\/bin\/bash<\/span><\/p>

sleep 30<\/span><\/p>

aplay -q -D default \/usr\/local\/share\/beoplay-sleep.wav<\/span><\/p>

sleep 1<\/span><\/p>

echo “1-1” > \/sys\/bus\/usb\/drivers\/usb\/unbind<\/span><\/p>

EOF’<\/span><\/p>

\u00a0<\/span><\/p>

sudo chmod +x \/usr\/local\/bin\/beoplay-sleep.sh<\/span><\/p>

\u00a0<\/span><\/p>

\"\u2139\" NOTE\u00a0\u00a0<\/span><\/b><\/span>Adjust the sleep 30 value to taste. Use 60 for more tolerance between tracks, 10 for faster standby.<\/span><\/p><\/div>

Step 9 \u2014 Fix sysfs Permissions<\/b><\/span><\/p><\/div>

Shairport-sync runs as an unprivileged user and cannot write to the USB bind\/unbind sysfs files by default. Apply world-write permission and create a udev rule to reapply it after every reboot:<\/span><\/p>

\u00a0<\/span><\/p>

# Apply immediately<\/span><\/p>

sudo chmod 0222 \/sys\/bus\/usb\/drivers\/usb\/bind<\/span><\/p>

sudo chmod 0222 \/sys\/bus\/usb\/drivers\/usb\/unbind<\/span><\/p>

\u00a0<\/span><\/p>

# Persist across reboots via udev<\/span><\/p>

sudo nano \/etc\/udev\/rules.d\/99-usb-bind.rules<\/span><\/p>

\u00a0<\/span><\/p>

Paste into the udev rules file:<\/span><\/p>

\u00a0<\/span><\/p>

SUBSYSTEM==”usb”, ACTION==”add|remove”, RUN+=”\/bin\/chmod 0222 \/sys\/bus\/usb\/drivers\/usb\/bind \/sys\/bus\/usb\/drivers\/usb\/unbind”<\/span><\/p>

\u00a0<\/span><\/p>

Step 10 \u2014 Boot Services<\/b><\/span><\/p><\/div>

Create a boot service that pre-binds the A8 and applies sysfs permissions before shairport-sync starts:<\/span><\/p>

\u00a0<\/span><\/p>

sudo nano \/etc\/systemd\/system\/beoplay-init.service<\/span><\/p>
