Hello, I was using the UCA222 interface and tried switching to the Focusrite Solo. I went to the interface and selected ‘USB Generic Device’ and set the configuration below, as I found here on the forum, but my Zynthian wouldn’t start anymore. It gave an Audio/Midi error.

`-P 70 -t 2000 -s -d alsa -d hw:USB -r 48000 -p 256 -n 2 -X raw`

I tried to revert via the command line, changing the ENV\_VAR file to the content below, but it still won’t start. Same Audio/Midi screen error:

bash

```auto
export SOUNDCARD_NAME="RBPi Headphones"
export SOUNDCARD_CONFIG="dtparam=audio=on\naudio_pwm_mode=2"
export SOUNDCARD_MIXER="Headphone"
export JACKD_OPTIONS="-P 70 -s -d alsa -d hw:Headphones -r 48000 -p 512 -n 3 -o 2 -X raw"

```

Could someone help me?

Using the terminal in the webconf run `aplay -l` and paste the output here. That will give you the correct device name.
