Hi All!
Legacy kernel says: "Enabled audio devices: analog, 8 channel HDMI, spdif and I2S (if wired and enabled in HW configuration)"
But there is no multi channel device listed in aplay -L , like surround51, surround71, etc.
With "speaker-test -D default:sunxisndhdmi -c 6 -t wav", We got a downmixed stereo result.
Receiver device is a BEM-182 Broadcast Monitor on its HDMI input - only 2 VU-meter band appears. Other test setup is the same receiver in SDI input mode with an HDMI to SDI converter. Specs of this adapter declares that it supports 8 channel, and this time 8 VU-meter band appears on the monitor so device is ready to receive multi-channel audio, but the 6-8CH audio transmission is still downmixed to stereo...
Are there anything that should be switched manually / reconfigured on the BPi transmitter side? Or is it an incompatibility situation?
Best regards,
Peter
