Hi,
I installed the device in RPI 2 B, Kodi recogniced properly de device and everything seemed ok, but found this issue when I ran alsamixer:
Front slider-> ok
Rear slider-> manage central speaker.
Central slider-> manage rear left speaker.
Subwofer slider-> manage rear right speaker.
On the other side, speaker-test work fine, every speaker sounds with its correct name, these are some outputs.

Is there any way to configure alsamixer to work properly?
Thanks in advance.
