Lumia 800: Speaker problem, no sound.

I can confirm that if the phone 'thinks' it has a headset, the audio from the phone is diverted through the headset.

I managed to solve sound disappearing from my phone when I look directly into the headset socket and found something inside it.

It turned out to be a small piece of tissue stuck inside the hole. I managed to dig it out with a small toothpick and the phone speaker is working again.

I remembered now that when the last time I was using it when it was still working fine, my earphone jack didn't want to go into the headset socket and I forced it in. It must have been that a small piece of tissue got logged inside it when I had the phone, the earphone and my tissue all inside my jacket pocket. How it happened, I've no idea.

So, take a look inside the headset socket and see if there's anything inside there which should't be there. I'm so relieved that I was able to 'fix' my phone without resorting to long and expensive repair.

Indeed.

If you do manage to resolve this issue, you might want to spend a few pounds\dollars on a 3.5mm jack cap.  Just a little silicon plug to cover the jack.  It's suprisingly vulnerable to getting grit and fluff inside.

I've had to replace the entire jack itself as there was grit caught in the sensor that wasn't going to budge.  It's not a huge repair, but don't try to do it yourself unless you really know what you're doing.  For the small price of a repair, the parts cost barely £10 so with labour you're not looking at much more than £30-£40 depending on who you visit it's not worth risking your £400 phone!

It would be nice if the jack port itself however came with a cap similar to the charging port.  there's no reason for it to be left open as it is.  Alternatively, a software update to disable\enable the jack when desired would be a soft fix for this, as the mechanics of the port still work despite the sensor issue.

I have same problem with my Nokia 710. Here is what i tried and non of them worked :(

1. Removed all software i installed after i bought the phone
2. Restored Factory settings
3. There is nothing inside the headset jack
4. All buttons are working fine
5. Diagnostics doesnt show anything

Normal phone calls with earphone and mic works. Surprisingly, headphone and AUX port works. Other than that, No ringtons, no alarms, no radio, no MP3 sound and no video sound. The speaker is just DEAD. I know many people gone thru same problem and no one from the Nokia seems to reply. Nutshell, please dont buy any Nokia Lumia.
