The UCA222 connects me with a Raspberry Pi with an AV receiver, since the internal sound chip of the Raspberry Pi unfortunately offers rather modest output quality. This task of mastering the device properly, the sound quality is perfect.
The operating system is in use Volumio, the music will be streamed via DLNA mobile phones, laptops, etc..
Really pleasing: There is no installation, configuration, etc. necessary, the device is detected automatically.
So if you want help to better sound quality its Raspberry Pi, the UCA222 is this ideal!
