Help Needed to trouble shoot my weird headphone (sensor) problem (Solved)
 

Hi Guys,

Can someone please help me troubleshoot my weird headphone (jack/sensor) problem.
I have headphone daemon and media box installed for months no problems at all.

Then, It happened 2 days ago, i was listening to music using media box then i got a call and unplugged my headphone to take the call. After that, the headphone socket/sensor is acting weird since. The phone often doesn't recognise when the headphone plugged in.
I think the socket is still working as when i plug the headphone in i still can hear little static noise and if i try like 5-6 times the phone will eventually recognise the headphone. I'm a noob and don't know enough to trouble shoot this. :cool:

Is there anyway we can reset the process that detect/monitor the state of the headphone socket?

I haven't tried re-flash it as i am still reluctant to go that path because i don't want to re-install everything again.

Sorry if my explanation is not clear enough. please feel free to ask more question and any suggestion is welcome :D

EDIT: Just plugged the headphone in, Healthcheck saying that the headphone is connected. But the phone(status area) doesn't detect it (no headphone icon). Hence, the sound/music is playing out to speaker

Re: Help Needed to trouble shoot my weird headphone (sensor) problem
 

I have the exact same problem -- headset stopped working after I unplugged the headset mid music listening (for a while, it worked if I unplugged/re-plugged 5-6 times; after a while, I only got mono, and now even that technique has completely stopped working)
Running dmesg in the terminal shows that the device recognises the headset has been plugged in, but no audio and no status bar icon.

I've come to the conclusion it is a problem with my headset as my colleague's N900 refuses to recognise my headset too

Interestingly, the headset works fine if I use a short "3.5mm headset extension cable", which is bizarre (except that the remote button and microphone now do not work) -- maybe it needs some additional info from the remote that it's not getting, which was the original cause of the non-recognising?

Anyway, perhaps try your headset in a different phone?
Try it with an extension cable if you have one

Perhaps someone else has some better ideas....

Hi Thegman,

I took your advice and tried the headset with an iphone. The headset is working fine. I can hear music well out of the headset. I can't try it with another n900 though. None of my friends is using n900 T-T.
But thanks for your advice anyway really appreciate it.

Re: Help Needed to trouble shoot my weird headphone (sensor) problem
 

Healthcheck really just detects if there is something in there, not if it is functional... i know that headsets that work in iequipment normally dont work in the N900 - theres a few threads on that.

Hi noobmonkey,

thanks for ur advice. i did search a bit more but all i could find is the issue with some other headsets that is not fully functional or not working with the phone.
My headset is the original one that comes with the box.

and my thought would be that if the healtcheck can detect if there's something in the socket. why the phone environment can't detect it and give me the headset icon in the status bar.

is the headset sensor/monitoring process different?

Re: Help Needed to trouble shoot my weird headphone (sensor) problem
 

I had the same problem but after rebooting the device a few times fixed it.
From what I remember, this is what I did,

>Insert the headphone and then shutdown and restart. make sure headphone is working, stop the music.
>Then remove the headphone , restart.

I remember doing sth like this and it got okay after that.. I dont have that problem anymore. :)

Hi PathFinder,

I have tried that several times with no avail.
at last, i decided to re-flash my device but the problem still persists.

so i guess, it is what "noobmonkey" and "thegman" said that there is a fault some where with the headset socket or the headset itself.

I'll drop it at Nokia Care this weekend and hopefully i can claim the fix or new headset on the warranty T-T.

Thanks for the advice guys.

Re: Help Needed to trouble shoot my weird headphone (sensor) problem
 

btw... I'm pretty sure that it's not the N900 (in my case) as it works with a different headset (or even the same headset with an extension lead) -- the smoking gun is that my headset does not work in a different N900, but does in other phones

Also, the headset is recognised by the N900 (via dmesg) but just no statusbar icon or audio routing.
Anyone know how the N900 recognises it's a headset with mic and end call button and not a standard headphone? I assume that's the reason I don't get an icon as something's bust in the headset mic/end call button

I couldn't bear to be without my N900 for 3weeks or whatever Nokia care take to sort it out, so I've decided to live with the headset+ extension lead :)

Re: Help Needed to trouble shoot my weird headphone (sensor) problem
 

I am also having problems with my headset
.
My original headset seems to be broken, not being recognised as a headset by my N900 and not working on a Desire either. I have access to 2 other headsets (Desire stock and Zagg Smartbuds), both of which are recognised as headphones (not headsets) very intermittently, although they record as a "headphone (GPIO 177) is now connected" in dmesg with every connection.

I have found that if I depress the microphone button I get a much better success rate with recognition. When they do work, the sound quality is poor unless again I depress the microphone button.

Is it that these headsets are not compatible with the N900? Do the stock headsets show as "headphones" or "headsets" in dmesg (I would check this myself, but I do not have access to a working pair of stock headsets)?

Thanks
Mark

Re: Help Needed to trouble shoot my weird headphone (sensor) problem
 

I had a problem where my headset was not being recognised a while back too. I remembered from another old Nokia handset that headset profiles are stored in with the handset profiles so editing a profile might influence it.

And it did. I cannot remember if I simply changed profiles from 'general' to 'silent' or if I actually edited a profile and tinkered as well, but this solved my problem. I hope it works for you too.

Hi guys
sorry for not following the thread for the past month. thanks all of you for the input.
the issue seems to be the headset itself as thegman mentioned. Even though the headset is still working with other devices but not with my beloved n900.

i've come to conclusion as i tried a cheap old nokia headphone and the n900 detected it straight away and the mic on it also works.

for some reasons or somehow my n900 messed my headphone up.
i'm now using a bluetooth headphone to avoid this in the future.
i don't know if it's reasonable or right or not but i'll mark the thread as solved so noone will scratch their heads for my issue no more.

thanks again to all trying to help me. your effort is really appreciated.

Re: Help Needed to trouble shoot my weird headphone (sensor) problem (Solved)
 

Hallo people i have to say that this issue and thread is NOT solved so i ask u people to help me detecting my headphone to my N900.

i am facing exactly the same problem as above right know and what i could do to get my headphone working is to swap with it with another headset and thats the only way rightm know how i am (actifying my headset through swap) the head phone works only its not reconized at ones by the phone but with swap it does but after reboot with the headset connected the problem remains and then the only way to get it reconized by the phone is to swap with another headset and to be honest i am tired of doing that.

so please help me with ur knowledge people

is there a way to reset the socket or something in that way?

let me know please

thank u

Ali

Hi Ali,

Sorry to hear that you also have the problem.
Your symptom is a little bit different from mine. Your workaround didn't work in my case. Swapping around didn't get the phone to recognise my headphone.
Maybe someone might be able to help you with the issue.
I don't know enough to be of help. Sorry mate >_<

Re: Help Needed to trouble shoot my weird headphone (sensor) problem (Solved)
 

Well, I'm just joining to this thread, to keep it alive, as I'm just having the same problem. As reference, in mi case the headphone was working perfectly last night. I had the headset around my neck in the car, and when I got off, I accidentally stepped on the plug on the headset, causing it to be pull violently. After then, the problem started to appear.

Just guessing, wouldn't it be very poor constructed headphones the reason for this error?

Re: Help Needed to trouble shoot my weird headphone (sensor) problem (Solved)
 

Yeah, I had the same problem before. I got my headphone replaced by Nokia (took 10 days).
From another thread and from what i understand, N900 is a "serial headphone killer" as said by someone else. The thing is, when u pull the headset out when something is playing in the background (call/music), something shorts out and N900 stops recognising it. For more details, I suggest u search the other headphone threads, but pretty sure that this is the reason.

Agreeing with this.... Reproduced the same instance for 4 times already :p

Does your FM-radio application detect the headset?
In qradio you can switch between speakers and headset, that did the trick for me.
