Re: N900 no mic audio

and here's the output from a good unit. You can see the mics at device 24:[0-0] and 25:[0-1]

0: [ 0] : control
16: [ 0- 0]: digital audio playback
17: [ 0- 1]: digital audio playback
24: [ 0- 0]: digital audio capture
25: [ 0- 1]: digital audio capture
33: : timer

If they do use the same path, it becomes obvious that it's just faulty hardware
EDIT: could people please start posting serial numbers?

Mr Grim I am inclined to agree with you, but no harm in looking at both. You can see from the /proc/asound/devices there appear to be two mic devices

I need to make a note to do the same next week.
BTW you need to change your footer :)

or not...:confused:

Re: N900 no mic audio

Hi all,

I am no expert in linux but I checked the Summit device's log file it seems to me the log for audio driver is:
[ 2.940551] ASoC version 0.13.2
[ 2.954132] AIC3X Audio Codec 0.2
[ 2.956695] asoc: tlv320aic3x <-> omap-mcbsp-dai-0 mapping ok
[ 2.958221] asoc: Bluetooth codec <-> omap-mcbsp-dai-1 mapping ok
[ 3.010009] input: RX51 (tlv320aic3x) Jack as /class/input/input2
[ 3.034088] ALSA device list:
[ 3.034149] #0: RX51 (tlv320aic3x)

[ EDIT ] A quick google seems to suggest tlv320 is an audio codec.

Maybe someone can check the folder
[ 3.010009] input: RX51 (tlv320aic3x) Jack as /class/input/input2
and see what input2 points to.....

By the way the debounce clock message should not be something to worry about. If my guess right it's just a filter to filter out asynchronous signal on the MMC data bus. Maybe it's not needed so Nokia didn't use it.

Surely this is a device where draining the battery is inevitable from to time, probably when you're in the middle of an important call :) because it's not got that much battery life if you're out using it all day.

That's the opposite of what my first Nokia phone's manual said (also using an Li-ion battery). It advised fully charging and discharging for a couple of cycles at the beginning.

Have the battery designs changed to reverse this advice completely?

Also: You said if the battery is fully discharged, it will be impossible to charge it because the N900 cannot boot into charging mode. Where does "accidental discharge-till-it-turns-off" fit into this? Will that brick the device, or that an incomplete discharge which turns it off by hitting a threshold?

Re: N900 no mic audio

Are you guys sure about this discharge thing? Mine has shut down on several occasions because of discharged battery but I never had any problems charging it. I know though that charging from the data cable sometimes doesn't trigger because it is actually software controlled. However the dumb power socket charger should charge like a champ.

Re: N900 no mic audio

As requested.

Code:

~ $ cat /proc/asound/devices

 0: [ 0]   : control

 16: [ 0- 0]: digital audio playback

 17: [ 0- 1]: digital audio playback

 24: [ 0- 0]: digital audio capture

 25: [ 0- 1]: digital audio capture

 33:        : timer

~ $

Same as the previous quoted output.

Re: N900 no mic audio

I'm pretty sure the device shuts down with something like 5% charge so it has some to spare to keep settings without eating into the internal battery. So if you don't try to hard to discharge it, you should be fine
Now can we get back to the subject? I see the serial numbers are kinda wide apart, if it's a manufacturing problem it's most likely intermittent

looks like all the software and sound hardware is coming up fine.
and when you run alsamixer do you see the mixer for the audio capture? if you do check that the mixer is turned all the way up.

and then try an audio capture using :arecord

Re: N900 no mic audio

spoke to my girlfriend and she said the audio was crisp!

I didn't tell her I had the phone but she noticed the difference right away so iono

They are not wide apart if you look closely.
Other UK users receiving theirs assuming from the same batch because they were all on the same flight from Germany, did not have the issue.

The main difference was the others did not charge their N900s before turning it on for the first time.

Like someone mentioned before there might be static from the phone. I think the hardware got fried?

Re: N900 no mic audio

3 so far, and the only commonality at the moment is the 356938030154
mine ends 52. We really need some more serial number though tbh

Re: N900 no mic audio

Nuknuk and Maemo only 50 apart? Is that a clue?

and lets be honest here, all those who have got their phones atm are what 50-100 people?

He hasn't received his yet so you can't consider his as not working

Exactly, i'm just preying and hoping at the moment, but it looks like im a few thousand apart.

Re: N900 no mic audio

There should be no direct correlation between fully charging a battery to boot into an OS and the success/failure of that for which a microphone works.

People should be whinging to Nokia considerable amounts / threaten to tell popular news blogs sites, et cetera et cetera. Make them do their damn jobs.

Re: N900 no mic audio

Yeah this is something basic. Very very basic.

Re: N900 no mic audio

What type of mic is it? If it's a mic that needs a DC current, maybe someone loaded the parts placement machine backwards and some of them got placed with the wrong polarity?

That's pretty much irrelevant, assuming no one wants to open the device and re-solder the mic (if this turns out to be the problem, which i doubt).
If it's hardware, i'm afraid there really is only one solution: return

Re: N900 no mic audio

Does anyone have any problems with TV Out ? because that doesn't work for me either.

I'll test it out as soon as my girlfriend finishes watching a movie on the TV. I'll load up a vid onto it in the mean time. some peep show season 6 maybe.

yes.. i am getting mine as well but still in doubt. also because of these failures im reading on the forum.

could anyone create a POLL in a new topic (i don't know how to create a poll) with the options "works perfectly out of the box, no problems", "hardware issue", "software issue" or whatever seems appropriate to the poster. (maybe also the option: works perfect but unhappy with performance/didnt live up to expectations by far)

i would like to see percentages of how many people are experiencing problems. this might be a good way to sum these up.

Yep, you probably will ;) I rave on about the phone, and no-one else I know has even heard of it, so I would be :o:o:o:o:o:o:o:o to get a broken one too.
Lets hope these clever ppl here can come up with a solution which saves sending it back.

Re: N900 no mic audio

There are a few people in The Netherlands, including me, who are having the same problem. I returned mine to Nokia today. My serial number is *6792.

I also had the same problem as the guy in this thread, and fixed it by reflashing with the eMMC rom. And then found out the microphone was broken :(
