Can be your computer don't have enough power processor.

I got it to work . But in general how does make sense to configure the system? I would say that the dac should play dsd as dsd and pcm as part. Is there any benefit to play pcm in DoP ?

[merlin el mago]

No, is the the same SQ DoP than native DSD.

 

[merlin el mago]

I'm sorry confused the question, my answer was DSD related, never heard PCM in DoP because DoP is PCM packed DSD.

I mange to play anything now, DSD64, DSD128 and DSD256. The only strange thing is that when I play the DSD256 files from 2L (The only one I have) the buffalo detects PCM 176KHz instead.
Not really a big issue as there are not really content available and I am not sure where is come from. It could be that JRiver is doing something. I am curious if you have something similar.

When you use JRiver DSD256 is available?

Cheers

I don't understand your question

Tools > Options > Audio > Settings.

BTW I don't use JRiver....

 

[merlin el mago]

176KHz is DSD64, please post pics of your JRiver settings

Attached are the settings. Reading on the bottom of the windows you can see what actually happens when playing DSD64 and DSD256. I guess Jriver converts DSD256 to PCM 176 on the fly, for some reason.

For the rest, everything if pretty cool !!!

How is configured the WaveIO?

I don't know if the latest drivers supplied by Lucian includes the Thesycon for DSD256 & DSD512.

 

[Nikon1975]

I use Mac, no driver

 

[merlin el mago]

Could you post pic of "device settings".

 

[merlin el mago]

Did you tried increasing the buffer? what's your DAC if you have any?

 

[Nikon1975]

The DAC is a Buffalo 2. JRiver on Mac bypasses the device settings. I 'll try the buffer.

[merlin el mago]

I asked DAC to be sure is able to play DSD256

 

[Nikon1975]

Well the computer does not have visibility on what DAC I use. If it would output DSD256 and the DAC would not support it, I would just get no sound. In this case, it actually works, but JRiver takes the initiative to convert it to PCM.

It's just a curiosity, as I don't get to use it.

Is possible your Mac doesn't have enough power processor and JRiver downsamples or there is something wrong in the Buffalo side: could you check the SW1 & SW2 switches?

 

[Nikon1975]

Mistery solved: DSD256 is enabled only on JRiver 21, later versions. Update should fix this, but I can check only tomorrow.
