DE10 Standard Audio Demos not working...

[Nandan Dayal]

Hello,

I bought the DE10 Standard and am having issues trying to run the demos related to audio.

I am trying to run the two demos, DE10_Standard_Audio, and DE10_Standard_i2sound, while connecting apple headphones to line out, and 3.5 lavalier microphone to mic in, but I am not able to record anything and play it back for the 1st demo, and I don\'t hear anything when I speak into the microphone for the second demo either. The microphone and headphones work fine on my laptop. This is the microphone specifically: https://www.amazon.com/Professional-Microphone-Omnidirectional-Recording-Conference/dp/B01AG56HYQ

I also tried another mic and still to avail

I tried another mic as well and still to no avail. I\'m so confused, it seems like it should work.

Can anyone offer any advice at all? I know this may be too general of a question, but I can provide any other information needed.

Thanks!!

It appears that microphone needs the socket to provide power. A quick
glance at the DE10 Standard user guide doesn\'t show any power output on the
Mic In port. It would be worth checking the schematic to see if power is
actually provided.

Perhaps see if the demo will accept audio via the line-in port, which
doesn\'t need to provide power? That would need to generated from a
line-level audio source.

Hello,

Thanks for the response. The demo does accept audio via line-in port, but that won\'t allow a microphone right? It only allows other types of audio sources. I specifically want to work with omnidirectional microphones because of a project I\'ll be undertaking.

A Line-in port and a microphone port are different. Some microphones
need a bit of power, and most microphones are a lot lower signal level
than a Line In/Out type signal.

You may need a pre-amp module to up the signal from the microphone to
the level the line-in wants.

You may need a pre-amp module to up the signal from the microphone to
the level the line-in wants.

I see. This may be a silly question, but I\'m not quite familiar with mic-in vs line-in, so what sort of audio sources would support line-in? I want to be able to try connecting an audio source to line-in to see if I can\'t use a microphone, at least something works.

Also, is there an easy way to find a pre-amp module to amp up the signal from the microphone?

Thanks,
Nandan

Line-In is designed to connect to Line-Outs of pre-amplifiers, one
active audio component feeding sound to another. Often a headphone
output would work too (not a big speaker output, that may have too
strong of a signal).

Most powered audio devices, if not designed just to power big speakers,
will have an output usable as a line-out, and is often labeled as such.
And as I said, normally a headphone out will be good enough to drive a
line-in
