Hello. For my birthday, friends gave me a Zishan Z5 player. The joy was short-lived. It does not contain the promised DTS 5.1. The coaxial switch in the player menu does not work, and it is impossible to find any of the promised firmware. I kindly ask you to explain to me how to enable DTS 5.1. I have an AV receiver ONKYO - 805 for this. I also kindly ask you to explain to me how to activate the coaxial digital output. This is the main thing I want to know. I've contacted many sites, but no one knows how to help. You are my last hope. If you don't help, I'll sell it. Thanks in advance.
