No, that is for devices that implement two stereo devices in hardware
and should be seen as a single 4.0 device by software.

2018-02-03 Thread Samuel Nicholas 
So whilst really trying to get my head around the syntax of the
configuration files, I figured the only way i truly could was to read
the source code.

whilst i was doing that i found this interesting configuration file
src/conf/cards/USB-Audio.conf

on lines 22 starts the description of configuring the usb device to be
two stereo devices not  a surround40

I'm not at home with my mix deck so cant test but its promising, i
might be able to fix not just my personal configuration but submit a
pull request to fix everyone's

Hi Samuel.

I think I have a similar problem with the Audient iD14
. Maybe we
could collaborate?

I haven't received many responses from the mailing list, so grateful for
Robert Bielik's suggestion.

Looks like the dshare

plugin
has some parameters I'm not familiar with. What's new?! :-) Hope I can find
information to demystify. Will share when I do. Please do the same.

As a backup I have started reading Linux Device Drivers
 and have asked Audient for their help.

Here are some other resources I have found.

A close look at ALSA 
Linux ALSA sound notes 
Writing an ALSA Driver

ALSA Runtime arguments in configuration files


My strategy has just been to read and reread and keep trying to figure it
out. I imagine it's going to take some time. :-)

Charles
