HifiBerry DAC8x

[wkl3968]

Just started testing the HifiBerry DAC8x as shown in the photo. it works for Channel 1 and 2 Stereo out of the box with the right config.txt. dtoverlay=hifiberry-dac8x. I also tried to duplicate the 1-2 channels to channel 3 to 8 using qpwgraph as shown in the photo but the setting is not sustained after reboot. still need to figure out how to approach this. the main reason I want to use a hifiberry DAC8x because of the hires audio support, can setup different sound stage (4.1, 5.1, 7.1 and etc) and most importantly, I want the phone call or phone navigation only output from certain channels (not all). Im looking for guidance on how to do this.

Here is the hardware setup. It is sleek and high quality. I need to spend time to setup correctly and have the ability to customize the audio piping. Any guidance will be appreciated.

After configuring the routing using qpwgraph, you can save it to a file and restore it (e.g., in hudiy_startup.sh) using the following command:

Code: Select all

qpwgraph --minimized --activated --exclusive saved_routing.qpwgraph

Is it possible to pipe the Bluetooth or phone call or navigation from phone to a certain channels and have independent volume control?
