Hi @Happy123321,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

If the audio jack on your HP 17-cn0xxx laptop has stopped working, here’s how to troubleshoot and fix it:

Step-by-Step Fix for Audio Jack Not Working

1. Check Basic Settings

• Plug in your headphones and go to: 
  • Settings > System > Sound
• Under Output, make sure your headphones are selected.
• If not listed, click Manage sound devices and enable them.

2. Update Audio Drivers

• Press Windows + X → Device Manager.
• Expand Sound, video and game controllers.
• Right-click your audio device (Realtek or Conexant) → Update driver.
• Choose Search automatically for drivers.
• Alternatively, download the latest driver from: 👉 HP Laptop 17-cn0xxx (6B9F0U8) | HP® Support

3. Run HP Hardware Diagnostics

• Restart and press Esc repeatedly → F2 → Component Tests > Audio.
• This checks if the jack hardware is functioning.

4. Check for Windows Updates

• Go to Settings > Windows Update and install all updates.

5. Inspect the Jack Physically

• Ensure no dust or debris is inside.
• If the jack feels loose or doesn’t detect any device, it may be a hardware fault.

I hope this helps.

Take care and have an amazing day!

Thank you, for your honesty, and advice. Having bought a new pair of headphones, I then found that there was a two month delivery for them. So I bought a cheapy pair with 3 day delivery! On day four they arrived. With a four pin plug. I didn't even know that there was such a thing! I'll get it cut off, one day. I have two 3.5mm plugs on order, just in case that fixes my old headphones...I ordered another pair of expensive headphones, with a 3 day delivery! They arrived and I triumphantly plugged them in! Silence...New headphones, straight out of a sealed box, costing a bob or two, faulty? I found a socket on the back of the TV. The headphones worked. My old-old headphones worked. Botheration. Maybe I should have taken HP up on their amazingly timed offers. Time after time they had popped up on my screen, urging me to take up their offer of repairs.  I gave up and sent it away for repair. For a small charge, they laughingly said, that there was nothing wrong with it! It was a failed "update" which had switched off my headphone socket. So it wasn't shown, it wasn't listed! But hidden, was an ability, to switch ON a headphone! They did, and for only a modest fee. (Probably because I had given them so much amusement.) Today came your amazingly but complicated instructions. Which may have indeed worked! So I thank you for your endeavours and kindness.

Hi @Happy123321,

That’s such a thoughtful and wonderfully written note. Thank you for taking the time to share it.

We completely understand how frustrating that journey must have been, from ordering replacements, waiting for deliveries, discovering mysterious four-pin plugs, and then finding out it was a hidden software setting all along! It sounds like you handled it with both patience and good humor.

We’re truly glad things are finally working again, and we really appreciate your kind words about the support and guidance. If you ever need any more help (hopefully a less complicated kind next time!), We’ll be here and happy to assist.

Wishing you many hours of uninterrupted listening with your now-fully-functioning headphones! 

Take care and have a good day.
