How to use audient evo 4 or any other audio interface to record audio (without sys-usb)

McbXPdkWfyGbyvJvpXpw · July 15, 2021, 9:39am

Hi i have an audient evo 4 audio interface and i am running qubes without sys-usb. The microphone attached does not show up the devices to mount option in the device manager where other hard drives show up. Nor does the audio interface itself show up in that option.

Dom0 recognises audient evo 4 as a sound card and i can from the volume manager and audio manager in dom0, setup my audio-vm audacity to use audient evo4 for recording but when i start recording no sound comes in the track.
Any help on this ?
tl"dr audio interface recognised as sound card , can select option to use for recording in audio-qubes audacity, but no sound.

Not sure if I know how to help on this. Just dropping here a link:

Using External Audio Devices
============================

Why you want to use external audio devices
------------------------------------------

Qubes audio virtualization protocol does not implement latency reporting for security reasons, keeping the protocol as simple as possible.
Also, in a compromise between low latency and low CPU usage, latency may be around 200 ms.
So applications demanding higher audio quality (even Skype) need a better environment.
But Qubes flexibility fully allows that using external audio devices. 
These are mostly USB audio cards, but firewire devices also might be used.

Implementing external audio devices
-----------------------------------

First you need to identify an user VM dedicated to audio and [assign a device](https://www.qubes-os.org/doc/AssigningDevices) to it.
In the most common case the assigned device is the USB controller to which your USB audio card will be connected.
