DAC doesn't recognize hi-res files

@77jovian

Yes, JRiver for Mac also bypasses the OS's audio playback engine. So it will
adjust the sample rate according to the source file.

JRiver has the option to enable Direct/Exclusive Access to the audio device
and can also operate in Integer mode (all improvements in playing back
audio) provided you are using 10.6.8 or 10.9 - Integer mode was dropped in
10.7 and 10.8 - don't know why.

My main gripe with JRiver is that its legacy as a Windows application still
shows. It places menus/options in the weirdest of places that don't make
sense at times. That said, once you get used to it, it is extremely powerful and
flexible in what you can do.

FWIW, I have been JRiver almost exclusively these days. I really like its ability to
upsample everything to DSD2x which sounds better on my Playback Designs
MPS-5 and Teac UD-501.

I have recently upgraded my versions of Pure Music and Amarra to v2.x and
3.0 respectively so I may give them a test run soon to see if they will change
my mind.

@Effischer, you don't have to reset it before unplugging because the setting
for 192kHz or 96 or 44.1kHz etc that you change is specific to the audio
device - in this case, your DAC. So it should not interfere with the settings of
your built in audio device in the Mac.

@Czarivey
In case it wasn't clear enough the first time around,

The C50 has a MODERN DAC design housed in a classic/traditional McIntosh
enclosure so it does 32bit/192kHz over USB. So try to get your facts right
before shooting stuff out of your ass. Pardon the french.

"DIGITAL USB INPUT
1 (2.0, 32/192 Asynchronous)"

Also appreciate the info regarding the add-ins and your response to 77 on JRiver, Doggie. The note about resetting reminds me that I'm dealing with OS X, not something else. Don't always remember that OS X does what it's supposed to, not what it wants to. I finally drank the KoolAid a couple of years ago because I had so much trouble with stability on the WinTel platform my company supplied. Bought a MacBook Pro and run a virtual machine under VMWare for my company VPN. Gets me the super-stable Apple platform and prevents Win 7 Pro from crashing me out. What an improvement!

Anyway, since I'm very deliberate about adding or changing configurations, I'll check out my samples with the (thank you again) correct MIDI settings and decide where I want to go with add-ins. Have the long weekend to experiment, too. Have a great Independence Day holiday everyone!

Good luck :) and have fun.

Tried posting this yesterday, but something is up with A-Gon.

Regardless, I'll start by saying I'm just starting to fool around with using my PC as a source. Downloaded A-Gon's HD Tracks sampler a few weeks ago in 24/192 WAV format, and my MacBook Pro identifies the files as 24/192. Using a USB into my McIntosh C50 DAC, the C50 identifies https://vidmate.bid/ the files as 16/44.1. The C50 automatically sets DAC https://speedtest.vet/ resolution based on file, so that's not something I can adjust. I'm running the files directly from Finder, not iTunes. Can somebody tell me what I'm doing wrong?

 

I got this,...

Your DAC will display the sample rate as set in Audio MIDI Setup unless your Player software automatically sets the correct sample rate for each file as it is played. [iTunes will not do this but there are add-ons that will, along with other music players].

The Audio MIDI Setup example below is from my office Mac so you won't see a DAC listed. On your Mac, click on the DAC in the left column. Whatever the sample rate is set to in Audio MIDI Setup is what will be sent to your DAC regardless of the file sample rate. Try it. Now change the sample rate in Audio MIDI Setup. View your DAC and note the sample rate it shows. It should match what you chose in Audio MIDI Setup.

You need Player software that will automatically and correctly set the sample rate for each file you play.
