USB-Audio: Steinberg UR44 not getting expected results

2 Jun 2022


      alsa-project/alsa-ucm-conf issue #163 was opened from CameronNemo:
I am testing the following software:
* alsa-lib: 1.2.7
* alsa-utils: 1.2.7
* alsa-ucm-conf: 1.2.7
Unfortunately the changes for the Steinberg UR44 do not seem to be working as intended.
I am not seeing the expected mono inputs and stereo outputs that I see defined in `/usr/share/alsa/ucm2/USB-Audio/Steinberg/UR44-HiFi.conf`.
I am seeing the following from `aplay -L`:
```

    4.1 Surround output to Front, Rear and Subwoofer speakers

surround71:CARD=UR44,DEV=0
    Steinberg UR44, USB Audio
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
```
And the following from `arecord -L`:
```
