The E1 error on your Hisense Soundbar means the unit cannot detect a valid audio signal from the connected source, usually pointing to an HDMI ARC/eARC, optical, or Bluetooth connection problem. Checking your cable connections and input source settings usually clears it within a few minutes.

Error code E1
Meaning No audio signal detected from the selected input source
Severity Low — usually a cabling or settings issue, not a hardware fault
Time to fix 5–15 minutes
Tools needed None, though a spare HDMI or optical cable is useful for testing

What the E1 error means

When your Hisense Soundbar shows E1, it’s telling you that it’s powered on and listening for audio but isn’t receiving a signal from whichever input you’ve selected, such as HDMI ARC, optical, Bluetooth, or aux. This is a communication issue between the soundbar and your TV or other source device rather than an internal fault with the soundbar itself.

It’s one of the more common errors owners run into, similar to input-related codes seen on other brands like the Sonos Soundbar ERROR Error Code, and it’s almost always fixable without calling a technician.

Common causes

  • Wrong input source selected on the soundbar (e.g. set to Bluetooth when you’re using HDMI)
  • Loose, damaged, or poor-quality HDMI or optical cable
  • TV’s HDMI ARC/eARC setting is turned off or not configured correctly
  • Bluetooth connection dropped or was never paired properly
  • Source device (TV, games console, streaming box) is muted or set to the wrong audio output
  • Firmware glitch on the soundbar or connected TV

How to fix the E1 error

  1. Check the input source: Press the source/input button on the soundbar remote and cycle through until you match the connection you’re actually using (HDMI, optical, Bluetooth, or aux).
  2. Inspect and reseat cables: Unplug the HDMI or optical cable from both the soundbar and the TV, check for damage, and plug it back in firmly. Try a different cable if you have one.
  3. Enable ARC/eARC on your TV: Go into your TV’s sound settings and make sure HDMI-CEC and ARC/eARC are switched on. This setting is sometimes labelled differently depending on your TV brand, and issues here are common even on TVs themselves — similar to the Hisense Tv ERROR Error Code problems some owners see.
  4. Re-pair Bluetooth: If using Bluetooth, turn it off and back on on both devices, then re-pair from scratch rather than relying on an old saved connection.
  5. Restart both devices: Power off the soundbar and TV, unplug them from the mains for 30 seconds, then plug back in and turn on the TV first, followed by the soundbar.
  6. Update firmware: Check the Hisense support site or app for a firmware update for your soundbar model, as outdated firmware can cause signal detection issues.

FAQ

Why does my Hisense Soundbar show E1 only with certain HDMI ports?
Not all HDMI ports on a TV support ARC/eARC. Check your TV manual to find the correct ARC-labeled port and connect your soundbar there.

Will a factory reset fix the E1 error?
It can help if the issue is caused by a settings conflict, but try reseating cables and checking input source first since those fix the issue in most cases.

Is E1 a sign my soundbar is broken?
No, E1 almost always points to a connection or settings issue rather than a hardware fault, and it clears once the correct source and signal are restored.
