Re: N900 no mic audio

I reread your post Venomrush:

I plugged my phone into the mains before turning on for the first time, and then let it charge for an hour and then went out for dinner and came back around 5 hours later and plugged it into mains again. My mic IS working fine.

thanks

Never drain the battery, ever.

Mic still broken on mine after full re-install with Software Updater. Was worth a shot..

My post was really for EU chaps (UK to be more specific) with 220v power sockets.

Hardware issue it would seem. Thats a bummer. Sorry.

Yeah, 110v. Ah well, I'll never let me battery charge down anyway... super paranoid now. I may end up buying a spare battery to have for emergencies.

Received my N900 this morning (finally) but the microphone is not working ie. The other person on the call can not hear me.

Anyone have a similar problem or heard of this problem before ?? searched, but nothing.

To resolve Ive tried the following without any luck:-

- Flashed standalone
- Flashed NSU
- Call recorder software does not pickup anything up
- Phone works with headphones
- Mute / unmute doesnt do anything

Annoyed or what. Any suggestions ? Thanks

Just to point out- and I know this is VERY tenuous- but I have exactly this problem on my N95 as we speak and it suddenly went down week before last. A firmware update fixed it temporarily but it has gone again- just thought I'd throw that in for no reason.

Edit: and it shold be noted that sometimes its on outgoing calls, sometimes on in- and occasionally it actually works.

Re: N900 no mic audio

i got mine today no problems did a couple of tests over network then tested with voice recorder app from extras

can you post the output of dmesg in a terminal after a fresh reboot.
It would be interesting to see if the system has some problems loading the driver for the mic.

Can you qualify that Venonrush? Why would you not ever want to drain the battery? Surely with a battery that only lasts a day will run down completely several times a month by accident.

What good is a phone that you're constantly worried about having its battery drained? I'm confused...

Re: N900 no mic audio

Is there a maemo IRC channel or something - I just think it might be easier than growing threads exponentially.

Yes
http://maemo.org/community/irc/

Maemo community on channel: #maemo
Server: irc.freenode.net

Yeah, many of us hang out on #maemo on irc.freenode.net. Keep the tone sober and non-trollish though :)

Re: N900 no mic audio

Danke. As soon as I have anything to contribute I will check it out.

Re: N900 no mic audio

So the general advice is to charge the N900 to full before turning it on for the first time?

I am sorry but I can't imagine there being any link between charging and failure of the mic.
Most people won't wait for the device to be charged before playing with it, nor should they.
If 90% of people don't wait before use and 2% of people have a failed mic there is a pretty good chance that the 2% of people with failures didn't charge their device, it does not prove a link.
I would have thought looking at whether the mic is properly detected with correct drivers loaded would be a good first step.
I would also say that if plugging in an external mic works then you have proved to some extent that the software is fine. I would guess that it might be a hardware problem. It may be a batch of microphone were used that were bad and that final pass out testing did not cover checking the microphone (quite likely I would have thought).

Perhaps if you can post up your serial numbers then someone at the factory can work out what hardware was put in these.

Yup best to turn it upside and spin around three times whilst chanting maemo, maemo, maemo...

If it's a dud then it's a dud best to find out sooner rather than later!

If what people are saying about the driver not loading then it's fairly unforgivable for those units to have even made it out of the factory. Failures that can be detected in software are the easiest and most obvious ones, the microphone being a fairly critical component in the case of the N900.

Re: N900 no mic audio

If only the community knew it could have written a "Check everything on your N900 works" app and had it in extras ready for release :D

Re: N900 no mic audio

I have just opended mine an played with it for like 10 mins plugged charger in then made a call to test.... it worked fine :D

That's actually not a bad idea. People with bad mics could post their S/N here to see if they're close => bad batch of phones. Or maybe there's another pattern (multiples of 13?)

Not a bad idea at all. Especially if we could already spot some day of manufacturing.

Thanks for trying to solve this MikeC - I fear your post got lost in the distress.

Can you explain exactly the steps you are asking people to take to supply that information please: some folks here are new to all this. If you have a solution, you'll be the hero of the hour!

(Mine is ok, BTW)

Not wanting to steal MikeC's glory for his contribution, here's how to get dmesg output:
*open terminal (yup, no other option that i know of)
*type "dmesg" (no quotes)
*copy+paste
If the output seems enormous, try "dmesg | tail" to leave just the most recent (that's a straight bar, no quotes)

Re: N900 no mic audio

looking at the dmesg seems to imply the driver is loading compared to a known good unit. prob means a duf mic.

The driver is linked to the bluetooth, so maybe something strange there. can you have a play with turning the bluetooth on and off and see if makes a diff.

Just a few lines - anyone in know, know? :)

do we know the name of the driver?

Re: N900 no mic audio

Anyone have any clues to this MAJOR problem yet.

Re: N900 no mic audio

The problem is that even if the hardware was faulty - the driver could still load. It really would help to see if the serials on the units were part of a batch.

Re: N900 no mic audio

Nope, sorry, I can't seem to figure out the audio driver name.

.....

Well, if you would see that the driver doesn't load then you would be able to draw a conclusion... if the driver loads then I agree, no conclusion can be drawn.

Re: N900 no mic audio

Thanks for starting this thread - it's something that DDP orderers will have to remember checking quickly (due to the one-week return policy).

Yes.
It's highly unlikely that charging like described above will have anything to do with the failed mic. But as you won't know the state of the battery when you receive the N900 you should start with charging it. If you're impatient you could power it up after half an hour and continue charging, but you should avoid powering it on first thing. If you're unlucky you may suddenly have a completely empty battery and then you will not be able to charge the device - it needs to be able to boot to its "charge mode" because the charging is managed by software. And it's always powered through the battery, even when plugged in. A dead battery is a catch-22.

And to the other poster: It's very bad for the battery to do a deep discharge. If it needs to be charged often, charge it often. Every accidental discharge-till-it-turns-off will reduce the capacity and lifetime of the battery. This is how it is with lithium-ion and lithium-polymer batteries.

Re: N900 no mic audio

To see the audio driver, couldn't you just do:

lsmod | grep snd

and

cat /proc/asound/cards

?

nuknuk there are two tracks here

1. it would be useful to see your serial numbers
2. we trying to see if your sound driver is loading to isolate if its a hardware or software problem. Would you know how to get into the terminal ? and run some of the proposed commands :-

Cat /proc/asound/devices

Re: N900 no mic audio

I seriously don't think this is software. We'll need someone from nokia to confirm, but i think the headset mic and the embedded one use the same hardware from some point on, which implies the same software too. Are there separate controls for headset and embedded mic ?
If they do use the same path, it becomes obvious that it's just faulty hardware
EDIT: could people please start posting serial numbers?
