CAC-1080 no multichannel audio

2 replies

Hello,

I am using the flowing setup: AMD RX-560 => CSV-7300 => CAC-1080 => Onkyo TX-RZ730 I am unable to get 5.1/7.1/Atmos multichannel audio working. Only stereo audio works. When i connect the receiver direct (with HDMI) to the graphics card the multichannel audio works fine.

How can i fix this issue?

Hi Mack,

Not sure if the CSV-7300 is designed to handle active adapters like the CAC-1080. Maybe you should look into an MST from DP to HDMI?

When you say "connect the receiver direct (with HDMI) to the graphics card", do you mean AMD RX-560 HDMI => Onkyo TX-RZ730 ?

Does AMD RX-560 DispayPort => CAC-1080 => Onkyo TX-RZ730 work? If not, then the problem is with the CAC-1080, not the CSV-7300.

But the CAC-1080 product page does say:

- LPCM and compressed Audio encoding formats
- Max audio sample rate of 192 Khz x 8 Channel or 768 KHz x 2 Channel
