Audirvana 1.5.2 + Mytek 192: the Big White Noise Problem with DSD

[Leonardo Piras]

Hi everyone,

my setup is as follows:

2006 MacbookPro with 2Gbytes RAM -> a Mytek 192 DSD connected via Firewire -> Volume bypassed to a Musical Fidelity A5 amp -> Totem Forest loudspeakers.

 

With Audirvana+ 1.5.2 (paid version, no trial) i can't play any DSD file (64 or 128) without hearing an enormous amount of white noise which makes music unlistenable.

Audirvana+ 1.5.1 was the same.

 

Tried all possible DSD settings in audirvana, and also tried with USB 2.0 instead of Firewire. Same mess.

Audirvana support is unresponsive.

 

I am trying playing .DSF files and .ISO SACD as well.

 

I can't get Pure Music (trial version) to play any DSD file.

I also tried KORG audiogate and it works..but it appears to convert DSD to PCM real time as the DAC does not switch to "DSD".

Upgrade your Mytek firmware and use Automatic setting in Audivarna.

Firmware is the latest beta 1.7.5.1

Settings are automatic.

i have got the same problem of loud white noise along with the music during DSD playing.

Tried both Firewire and USB 2.0 with Audirvana but no luck.

The display shows "dsd" and i guess Native DSD is detected.

 

Mytek firmware updated 1.7.5

Audirvana+ 1.5.6

Macbook OS.X 10.6.8

Firewire driver 4.1.3

USB driver 2.00.11

 

Selected Automatic Detection for Native DSD capability and it shows "DSD over PCM standard 1.0" in the debug info.

 

If selecting dCS Scheme 1, no sound output.

 

Checked Exclusive access, Direct Mode and Integer mode.

 

Thanks in advance for help.
