In such way I would be able to detect frequencies up to 38460/2 = ~19230 Hz (with a single mic). But as my problem states, I have issues reading multiple channels. system March 23, 2014, 11:43am #6.

To start a conversion it should be either possible to do this in software with: Writing the value of the ADC1->CR2 register with a set ADON bit twice (first write will set the settings and the second write will trigger the conversion). As you are already doing this, I'm not sure why it doesn't work.
