Headphones not working - Sennheiser HDR 130 Consumer Headphones

There could be a few reasons why your headphones are not working with your Chromebook. Some possible solutions include:

1. Make sure your headphones are fully charged and turned on.
2. Check to see if your Chromebook's Bluetooth is turned on and that your headphones are paired with the device.
3. Try restarting both your Chromebook and headphones.
4. Make sure your Chromebook's operating system and drivers are up to date.
5. Check to see if there are any known compatibility issues between your headphones and Chromebook.
6. Try resetting your headphones to factory settings
7. Try using different headphones with your Chromebook to see if the problem is with the headphones or the Chromebook.

If none of these solutions work, you may need to contact the manufacturer of your headphones for further assistance.

your device speaker or head phone socket is defective.

First, try plugging in different headphones. If those work, then your headphones are broken and you need to replace them.

If those don't work, then please check to make sure you're not plugging them into the microphone jack - you'll see two identical plugs, usually the headphone one is marked with a pair of headphones.

If you're plugging known working headphones into the correct port, then your computer must logically be the broken thing.

Just found this and it worked! Hope it does for you as well:
There should be a button on the DVD remote control with a headphone symbol on it. Make sure the headphones are turned on(red indicator on earpiece) and push the headphone button on remote. The headphones will only work in the back seats of the vehicle. Once you have audio to the headphones, you should be able to hit the AM/FM button on the radio and listen to the radio while back passengers use the headphones for video.

Broken audio cable entering the transmitter or audio jack plug.

Power supply plug loose / faulty power supply.

yes its in the keyboard jack.

Connecting headphones to the system will disabled the internal speakers until the headphone jack is disconnected, at which such time the internal speakers should function again.

If you disconnect the headphones and the internal speakers are not re-activated, then there may be damaged to the microswitch in the jack. (Try rebooting after the headphones are disconnected too)

User problem!! The main TV volume and the headphone volume work independently so you can have the TV volume set at zero and use the headphone volume. However I suggest getting a pair of headphones with it's own volume control.

Trying re-syncing the transmitter and the headphones. Hold down the power buttons on both until they alternate red and blue blinking, worked for me and now they work just fine. Got that from the Logitech FAQ website.
