# No Sound from Your Speakers: Quick Troubleshooting

Step-by-step guide to diagnosing why your speakers have stopped producing sound.

Audio / Video

## Why You Might Have No Sound

There are several common reasons audio stops working. Most can be resolved without a service call.

### Check These First

1. **Is the correct input selected?** — If using a receiver (Sony, etc.), make sure it is set to the right input (HDMI 1, HDMI 2, etc.)
2. **Is the volume up and unmuted?** — Check both the TV volume and the receiver/amplifier volume
3. **Is the amplifier powered on?** — Check your equipment rack — the amplifier should have a power light on
4. **Are all cables connected?** — HDMI cables can work loose over time, especially behind wall-mounted TVs

### Specific Scenarios

**No sound from in-ceiling/in-wall speakers:**
- Check that the zone amplifier is powered on in your equipment rack
- If you have in-wall volume knobs, make sure they are turned up
- Restart the amplifier by unplugging it for 30 seconds
**No sound from a soundbar (Sonos Playbar/Episode):**
- Check the optical or HDMI cable connection between your TV and soundbar
- On your TV, go to **Settings > Audio Output** and verify it is set to the external speaker
- Power cycle the soundbar
**No sound in one room but other rooms work:**
- The issue is likely zone-specific — check the amplifier channel for that zone
- If using Control4, check the app to see if that room's audio is muted or volume is at zero

### When to Contact Smart Systems

If none of the above resolves the issue, the problem may be with wiring, a failed amplifier channel, or a programming change needed in Control4.
