[AudioI] Fwd: Octo sound card on Raspberry pi3 B+ aarch64

 Fabricio,

I don't think aarch64 has anything to do with it. Does more than one channel work?
Did you have to install the .deb package? On Raspbian, the only install you had to do was specify the dtloverlay on boot.

 Hello,

My research group purchased an OctoSoundCard a few years ago that we have been using for underwater acoustic applications. However, I would like to do an installation from scratch on a 64bit system (aarch64). After some research I performed the installation without errors and the card is recognized. However, I'm having some issues reading the channels to a wave file. I wonder if it is possible to use the Octo in this 64bit system.
I've been using the function "arecord -D plughw:CARD=audioinjectoroc,DEV=0 -f cd -c 1 -d 1 -r 96000 test.wav", which gives me an apparently swapped binary signal. I also tried using jackd and ecasound: "ecasound -q -C -f:s16_le,1,48000,i -i:jack,system:capture_3 -G:jack,,notransport -f:s16_le,1,48000, i -o:test.wav" which gives me the same strange result. I tried running examples from "gtkiostream ./test/ALSAFullDuplexMinScan" but the output says "overrun occurred".
Please see the attached pdf where I show the installation procedure and the results.

thanks in advance,
