Estou tentando produzir canais multi-pcm no meu Receiver TX-RZ900 da Onkyo no Fedora 25 com saída Intel Skylake HDMI.
Eu tive algumas informações úteis sobre este post Como eu configuro o PulseAudio para 7.1 Surround Sound através de HDMI? mas infelizmente as saídas de teste de alto-falante somente nos canais Front Left e Front Right
O AVR informa os canais certos:

Qualquer ajuda sobre este problema seria muito apreciada, eu passei muitas horas tentando resolver isso sem qualquer sorte até agora ...
