IKEA SYMFONISK Speakers Not Playing Audio

IKEA SYMFONISK speakers are built on Sonos technology and integrate with the Sonos ecosystem. This guide covers audio playback issues and connectivity problems.

Common Symptoms

• No audio output despite showing as playing
• Speaker not appearing in Sonos app
• Intermittent audio dropouts or stuttering
• AirPlay connection dropping frequently
• Voice commands not reaching the speaker

Basic Troubleshooting

1. Check Power and LED Status

• Verify speaker is plugged in and receiving power
• Check LED indicator (solid white = normal, flashing = issue)
• Try a different power outlet to rule out outlet issues
• Inspect power cable for damage

2. Verify Volume Settings

Multiple volume controls may be involved:

• Check speaker volume in Sonos app
• Check device volume (phone/tablet) if using AirPlay
• Verify stream volume in music app
• Check if speaker is muted in Sonos app

3. Network Connectivity

SYMFONISK speakers require stable WiFi:

• Confirm speaker is on same network as control device
• Check WiFi signal strength where speaker is located
• Restart router if multiple devices have connectivity issues
• Try connecting via Ethernet using Sonos Boost if available

Reconnecting to WiFi

If Speaker Lost Network Connection

1. Open Sonos app and look for speaker with orange warning
2. Tap on the speaker and select "Connect to WiFi"
3. Choose your WiFi network and enter password
4. Wait for connection to establish (2-3 minutes)

After Changing WiFi Password

1. Connect phone to new WiFi network
2. Open Sonos app—it will detect network change
3. Follow prompts to update speaker WiFi settings
4. Speaker will reboot and reconnect

Audio Quality Issues

Stuttering or Dropping Audio

Network congestion often causes audio issues:

• Use 5GHz WiFi if available (less interference)
• Move speaker closer to router or add WiFi extender
• Reduce interference from other 2.4GHz devices
• In Sonos app, check network quality under System > Network

Poor Sound Quality

• Check Sonos EQ settings (Settings > Room > Sound)
• Enable Loudness setting for low-volume listening
• Trueplay tune if using iOS device (improves room acoustics)
• Check audio source quality (streaming service settings)

AirPlay Issues

For AirPlay 2 connectivity problems:

1. Ensure speaker is updated to latest firmware
2. Verify iOS device and speaker are on same network
3. Restart both speaker and iOS device
4. Check Control Center—speaker should appear in AirPlay menu
5. If missing, remove and re-add speaker in Home app

Factory Reset Speaker

As a last resort, factory reset the speaker:

1. Unplug the speaker
2. Press and hold the Join button
3. While holding, plug speaker back in
4. Continue holding until LED flashes amber and white
5. Release button—speaker will reset
6. Set up as new speaker in Sonos app

When to Contact Support

Contact Sonos or IKEA support if:

• Speaker won't power on at all
• LED shows solid red or unusual pattern
• Factory reset doesn't resolve persistent issues
• Physical damage to speaker or lamp components
