Re: N900 no mic audio

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

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
