Hi dunghnguyen,
I switched the clock on the DAC+ off by adding the ",slave=on"
You switched off the main feature of the HifiBerry DAC + pro.
Some users asked us about the jitter on the Raspberry Pi data lines. The impact of jitter in digital sound transmissions is being discussed controversy. But we decided to give you the choice to have an ultra-low-jitter clock to the HiFiBerry DAC+. Therefore we developed the new DAC+ Pro. It comes with its own dual-domain clock circuit wich provides 2 separate clocks for 44.1/88.2/176.4 and 48/96/192kHz sample rates.
And it sounds better?
Can I do the same for my usb DAC on C2?
No
I ask because we cannot access the /boot/config.txt on C2?
You can not compare RP with ODROID C2 at this point.
The kernel used for the ODROID C2 image doesn't use device-tree-overlays for its I2S sound drivers.
My usb dac is Sabre9018 so the advice is to change to "dtoverlay=sabreberry32,slave".
The slave parameter is only valid for the HifiBerry I2S driver!
A USB DAC can not switched into slave or master mode, because it works totally different.
