I am running the latest build (24-03-2018) on a Raspberry Pi 3B via USB (DSD over PCM).
During the playback of DSD64 2.8 Mhz tracks to a TEAC UD-501 I hear a constant noise in the audio. When playing back DSD128 5.6 Mhz tracks on the same DAC, these tracks sound clear as water.
The TEAC UD-501 is only able to play up to DSD128 5.6 Mhz
Both tracks are sounding clear as water when I connect the DAC directly from a MacBook via USB (DSD over PCM).
In all cases I use Roon to play the tracks.
Can you please help and look these DSD64 tracks are not able to be played via the RPi without the noise?
