The audio interface has two Microphone/Line/Instrument inputs (1L, 2R), two Line outputs (1L, 2R) and one headphone output. The "problem" with this audio interface is that by default it exposes 6 hardware channels and ALSA recognizes it as a 5.1 audio system, so the files `E2x2.conf` and `E2x2-HiFi.conf` are to create convenient and user friendly profiles. Also, a `SectionVerb.EnableSequence` has been added to the file `E2x2-HiFi.conf` to disable the exposed hardware channels that are not used. USB identifier: `152a:8752` [alsa-info.txt](https://github.com/user-attachments/files/29563789/alsa-info.txt) I tested it in several applications like Firefox, Telegram, Discord etc, and also I recorded audio from Ardour (DAW), and all is working as expected.
