Re: Can the RCA inputs be used at all?

Heh. I've lost track of who it was gave me the correct answer, but here is the correct answer: Run this before you try to use the RCA inputs. /usr/sbin/alsactl --file /usr/share/doc/audioInjector/asound.state.RCA.thru.test restore The card will revert back to the default when it can. So you may have...

Re: New Stereo soundcard, no sound through RCA input.. Any help appreciated.

This'll do it. I came back to this forum because I had the same problem and somebody told me what to do, and it worked. I just finally got around to a full "production" test tonight. So, whoever it was that helped me so many months ago, thanks. I presently can't find the file that would have had the...

Re: RCA input w/ Volumio

I've posted a couple of times about not getting the RCA inputs to work.
(I'm using C++.) I'm drawing the conclusion that they just plain don't work

I wish I hadn't bought this thing.

Can the RCA inputs be used at all?

Can the RCA inputs be used at all, using any language? Python, C, C++? command line? How? Nothing I've done gets anything from the RCA inputs to the RCA outputs or the stereo jack. If I can get something from the RCA inputs to either of the stereo jack or the RCA outputs then maybe I can get some us...

Can't figure out the RCA plug inputs.

Ah, yes, I always forget: stereo soundcard, Pi recently installed from image file and up to date. This works. aplay /VOLUMES/gizmonics/ainjector/piano2.wav That is, I can play that file, and hear it. I have a C program which will capture from the onboard mic. In the interest of space I will not post...

Re: mcp3008

Ahh, I think I'm too late to do you any good, but here goes.

The mcp3008 is an SPI device. You'd need to turn it on via raspi-config,
of course. SPI and I2C won't interfere.

"Bit clock pin 12?"
The mcp3008 CLK is on pin 13. The corresponding Pi pin is 23. So I don't
know what you mean.
