Hi Tanu,

Based on test result below 4.0 setup is not supported by HW, I guess?


$ speaker-test -D surround40:CARD=Aureon51MkII --channels=4

speaker-test 1.0.26

Playback device is surround40:CARD=Aureon51MkII
Stream parameters are 48000Hz, S16_LE, 4 channels
Using 16 octaves of pink noise
Channels count (4) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument
