Only one record device is showing instead of 6

[ssk]

I intend to use 2 of the input channels, apply various processing and output 8 different streams. I further intend to use the other 4 other input channels for getting other input and use them for analysis, but, first, the card I have is 8/6 out/in, but I think I'm only seeing 8/1.

I am running Pi3, and Stretch.

Here are the results of my aplay -l and arecord -l

Code: Select all

$ aplay -l

To be specific, here are the listings of the octo on your system - always one deivce :

You may want to look at splitting the card into virtual sound cards which can be used independently ?

Here is a starter thread for how to do that :
