192kHz via USB from Mac

<< < (2/2)

kiwi:
I have an Emotiva DC-1 both at home and in my work rig, it happily does 192/24 and has a great headphone output.  I find it to be a brilliant little DAC. I love the knob for volume control.  It has native Mac playback support at 192.

If you're willing to wait a little longer, this Geek Pulse looks very promising.

I've got the Geek Pulse X (balanced model) ordered.

I just have JRiver configured to not change sampling rates for 192 or less.

One thing that looks odd, I don't think that USB Audio 1 can do 192khz.

Maybe I do not understand the question.  I used an old USB printer cable we had around.  It looks sort of like the one here: http://www.firefold.com/15ft-usb-cable-ab-ivory?gclid=CInF9fHYhrsCFTDhQgodWCUABw.

Hmm.  My trial on MC ran out, but it looks like I can get an extension.  If I get this working, I'll happily purchase MC.

fstanke:
JRiver extended my trial period.  Thanks very much.

I have the latest version of MC19 on my MacBook Pro and a Bryston BDA-2 connected with a generic USB printer cable. 

In MC I set

Player/Playback Options/Audio/Audio device/options/Bryston USB 2.0 Audio Out [Core Audio]

Player/Playback Options/Audio/Settings/DSP and Audio Format/Sample Rate/Input Output/192kHz 192kHz

Playing a 192 FLAC, the BDA-2 shows green on USB1, 192K0, Lock, and USB6.  But nothing comes out of the (analog) audio jacks. Why?   

If I switch to Opto-2 with a TOSlink cable connecting the Mac and DAC and select
Player/Playback Options/Audio/Audio device/options/Core Audio, I get sound with BDA-2 showing green on OPTO-2, 96K0, and Lock; and analog audio comes out.  This proves that I have the BDA-2 connected properly to the rest of the system.  So this issue is somewhere with the Mac and DAC or their connection.

Can you tell me what I might try to get 192/192 playing through the DAC?
