Hi all, I'm trying to make work xoscope in my n810. And canīt find any documentation regarding direct mic access coding.

The compiled code work fine.

Does anyone have any idea where to start?

I took a look inside maemo-recorder, but, it is using GSstreamer and that don't work for me.

Any help is welcomed

Thanks,

You'll find most Maemo multimedia applications are developed using the GStreamer framework. We have ALSA and ESD, but not OSS. Research if ALSA's OSS emulation is built in by default or not. OSS emulation through ALSA and ESD is doable, but known to have issues.

Thanks,
"arecord" can access to the mic.
I used it in this joke app.
I hope this helps you .

(EDIT)
There is a nice app called <eXtace>.
some screen shots




(EDIT2)
I found I can pass through the mic to ESD by the following command.

Code:
 arecord -v  -t raw  -f S16_LE | esdcat -r 8000 -m
