Those days are still here, posting this persons website or links to it are not allowed.

 

That said most all of know where it is etc...

 

On the ODAC with JRiver.

 

I have 2 ODACS and use JRiver.

 

Its fairly simple to do. I  use WIN 7 and a pc not a mac.

 

I would add the JRiver Intereact support forum is loaded with techie info etc.

 

The way I have mine setup is as follows:

 

DSP Studio:

Output Format checked, nothing else

Sample Rate set to No Change

Channels set to Source Number of Channels

No Mixing

No Subwoofer stuff

 

Playback Options:

Audio Output set to WASAPI

WASAPI Settings: Device Default or ODAC, Check Open Device for Exclusive Access, BitDepth set to Automatic,

Buffering set to 100ms default. If you have pops or clicks set lower...on one system this is set to 25ms. If you have issues at the default 100ms setting to higher times makes this worse.

 

All the other stuff on the Options Page is pretty much default.

 

With windows there are other WIN7 settings that need to be setup correctly as well but I don't know the MAC equivelents.

 

On a PC when the little ICON in the upper right side of the JRiver  screen turns "Blue" you basically have achieved BITPERFECT with the JRiver player....that is what the source is is the source out....

 

That said the OS settings may or may not impact these.

 

Glad you liking the O2 and ODAC....for the bucks you cant beat it....for sure.

 

All the best

Alex

I was actually making a veiled drug reference, lol. Never mind. I love the ODAC XL & O2 combo so much here's a couple of pictures...

For the Mac, output is set to ODAC. Let the different bit rates default. Any further question, you can PM me.

I've got my Mac set to ODAC in Sound Preferences. In Audio Midi Setup I've set output to 2ch/24bit @ 44.1khz. I had intended to set this to 96khz but it won't stick. Is this correct?

Mine seems to work. I'm still running the latest version of Mountain Lion if it makes any difference. Mavericks still seems to have too many issues for me to upgrade. XD



Speaking of which, this thread might come in handy to some people who use OS X.

I have bit perfect which works on top of iTunes. It automatically sets the matching bit/sample rate of the DAC with the music currently playing in iTunes.

My ODAC doesn't look like that in the left pane. I don't have the 64ch option. In the right pane you have it set to 16bit, not 24bit. I can make my screen look like yours when the player is stopped but as soon as I restart it goes back to 44.1khz, irrespective of whether I set it to 2ch-16bit or 2ch-24bit. Hmm...

I'm on Mavericks btw. You're not using JRiver though are you, Mike?

Oh whoops. I set it to 2ch-24bit now. Thanks for catching that! smily_headphones1.gif


The 64ch thing is a whole separate program/setting. You should have the 2 USB icons for the ODAC (1 for output, 1 for input).

Maybe JRiver Media Center has its own DAC options for the sampling rate and bit-depth. Or it may just be a bug with the software. I can't use the demo version of it since I wasted that opportunity back when it was in the beta stage for OS X (version 16 I think).

I definitely don't have the 64ch option. What would that be used for anyway?

Is soundflower something you installed yourself? Who made your ODAC?

I think your Music player is setting the dac to the correcponding bit/sample rate of the currently playing file. That is bit perfect playback (Not to be confused with bitperfect app).

I dunno what the 64ch thing is for.

Yes, Soundflower is a separate program I installed myself. I use it to capture audio from the computer to the computer (e.g. play audio in iTunes and record it with Audacity).


JDS Labs made my ODAC. I purchased it a few years ago, so the case was different from yours, but everything else should be the same.

Phew, you had me worried there. Yeah, the 64ch thing refers to recording channels. Many moons ago I had the same thing in Windows with the drivers for an M-Audio 2496Audiophile sound-card I had installed. I never used them but that's the MIDI default channel spread.

You're right about the bit perfect thing too. I tried a high-res version of Pink Floyd' "Momentary Lapse of Reason" - total waste of money btw, luckily I nicked it - and the setting persisted then reverted to 44.1khz.

All is well with our world's. As well as they can be anyway.
