ESI NeOn Audio/Midi interface compatibility issues

[lagtac]

I have an ESI NeOn Audio/Midi interface (http://www.esi-audio.com/products/neon/) with 4 input and 2 output channels. Audio out and midi seems to work with alsa/jack but no other devices are seen (0 input/output channels). Audio capture results in garbled signal. Also, alsa mixer only displays one PCM and Mic meters.

Recording through ALSA results in a garbled low fi signal:

Code: Select all

$ arecord -Dplughw:1  lala.wav

Recording with the device's available format results in a silent signal:

Code: Select all

$ arecord -Dplughw:1 -f S24_3LE -r 44100 lala.wav

Here is some more info:

Code: Select all

$ cat /proc/asound/card1/usbmixer

I am on a Dell Latitude 6430 laptop with 12GB RAM, i5-3340. It is running Arch with the 4.16 kernel, and the i3 window manager. No pulseaudio, only Alsa (and Jack audio server).

I understand the NeON is a usb 1 class compliant device, but there does not seem to be any other information available in the ALSA soundcard compatibility page for this particular model. I was thinking that a configuration similar to the M-Audio Fast Track Pro could be made to enable the device capabilities. (https://wiki.archlinux.org/index.php/Pr ... _Track_Pro). Or am i way off the mark?

Is there anything I can do to make this device work? It is old and rusty but it would be a shame to throw it away.

Thanks

ESI knowledgebase usually has answer that devices that are class-compliant or not supported on Linux but no mention of this device

ESI say 2 inputs and 2 outputs, with inputs either line-in or mic+hi-z. This sounds similar to their Maya22
