The goal is to access our T7's through ALSA (Advanced Linux Sound Architecture). Looked for related posts here but only found a distant cousin at kernel 2.6.12.
We can speak:
- Lib ALSA (Linux)
- Libjack (audio from jackaudio.org)
- Tiny ALSA
These our app supports. Is it possible? The simplest setup for our purpose would be a BeagleBone Black revC connected via USB to a T7, low sampling rates for up to 4 channels.
Would like to try it tomorrow, but it looks like we need to flash some BeagleBones with a Debian that holds kernel 3.18? Any updates here? These systems would be headless (.ie no monitor, accessed via ssh only)
What are we getting in to here? Is this a reasonable goal? Would a driver need to be written?
THANK YOU!

I am not very familiar with ALSA, but I do not believe we have any ALSA compatible drivers. T7 connections via USB are normally handled using bulk USB endpoint transfers of Modbus TCP frame data. Our USB docs have more specific information:

The recommended way to interface with our devices in Linux is with our LJM C/C++ library:

Thank you; We may be able to make that work. Will post back
