@Andrew-Naumenko wow, you're totally right! I wonder, is this a bug or intentional removal of feature? Perhaps @Lazar-Demin knows to comment? b195 version is still the old console, and it even pleads to upgrade to the latest firmware at the setup. Kind of awkward.

root@Omega-ABCD:~# aplay -Ll null Discard all samples (playback) or generate zero samples (capture) default:CARD=AudioI2S Audio-I2S, Default Audio Device sysdefault:CARD=AudioI2S Audio-I2S, Default Audio Device **** List of PLAYBACK Hardware Devices **** card 0: AudioI2S [Audio-I2S], device 0: ralink-i2s-HiFi HiFi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0

Another strange thing I have noticed is that the wav file playback by $ aplay Test.wav did not succeed: no sound, and Omega just shuts down after few seconds, no error message whatsoever. Not that I cannot survive with only mp3 file support, but something fishy is going on there.
