Crackling when playing 48kHz 24bit files in Roon 1.1

@chrisbyrd , @jossen, @Adam_Stettner, @alex_weiss ----- Thank you for the reports and the feedback. I would like to test in house with a sample of media from each of you to see if I can produce the same results. May I kindly ask each of you for the following in a PM addressed to me:

  1. A dropbox link with one song you are noticing this issue with.

  2. A description of your setup and what settings you are using in Roon .

My apologies if any of this information needs to be repeated, I want to make sure I have everything in front of me when I got to test the content :microscope:

Hi. Roon won’t play 48kHz files for me either (without distortion).

I believe this is fixed in 1.3.

Great. Any idea when 1.3 will be available?
It’s not a huge deal. Only applies to 9 albums out of a fairly large collection, but irritating when I go to play them.

When it’s been fully finished and tested. :slight_smile:
They won’t be sitting on it finished just to tease you all.

I’ve been having the same issue and it’s driving me nuts.

so have we determined an older version of OS X is the culprit?

I am running 10.10.5 and Roon 1.2

unlike a lot of the people who posted here, i have a TON of these files as one of my favorite bands releases every show they play in this format…

so either update to newest OS X or wait for Roon 1.3 i guess?

Hi @Keith_Adams, OS X version is not the culprit here. You will have to wait for 1.3 for the fix – hang tight!

HI Kevin,

just wanted to let you know that Roon 1.3 did not fix the issue. any ideas ?

Yeah I,m getting crackling and pops with Tidal Masters through Roon but if I play them through the Tidal MAc app ,everything plays nicely.

I am completely not impressed with the bugginess of this update to 1.3

Everything was working fine for me until this update.

@Keith_Adams @Jim_Honsberger

Can you let us know the details of your setup, especially your audio outputs and screenshots of your audio settings?

Thanks!

my set up in regard to solving crackling during playback of 24/28 files:

MacBook Pro 15
2.3g Intel i7
16GB Ram

OSX 10.10.5

Roon 1.3 build 196

Geek Out 1V0

music is on Western Digital My Passport Ultra 2T

8637 tracks

Crackling only occurs in playback of 24/48. all other formats are ok.

They’ll need the aforementioned screen shots of audio settings.

I just did a quick test and found no problem with any of my zones: laptop, Meridian streaming or RAAT.

Here are screenshots of my audio setup

Can you enable Exclusive Mode (first screenshot) and share what happens?

YES! that solved it!

but why? and by running this mode, what does that do to my set up?

the volume doesn’t seem as loud, it’s a bit easier to control. one issue i was always having is that the volume seemed to turn up by itself when i paused or stop playback. this seems to have addressed that.

It will allow Roon to gain exclusive use of your DAC, so it is able to output the audio stream directly. If you leave it unchecked, the stream is delivered to your operating system’s mixing device, which adds further manipulation (and sometimes – as you have seen – unwanted nastiness. :-)).

Hi all,

I’m having exactly this issue (and was about to create my own thread before finding this one). It only occurs when outputting the sound of 48kHz through my Mac speakers or through headphones, it’s fine through any DAC, but I’m on 1.4, so I guess the issue is still there?

(and by the way, on some such albums, Roon kind of “soft crashes”: it plays for a few seconds, then displays “no audio output found”. After a short while, the audio zones are available again.)

Do you have Exclusive Mode enabled on all zones?

Ah, my apologies, I did not read the comments above properly. Making the build-in output exclusive does sort out the problem. However, the only time I ever stick my headphones straight into my Mac is when I need to hear my operating system’s alerts, so that does not do the trick for me. But I understand it’s not necessarily entirely due to Roon though.
