So to be clear… You have a LS-ADAT PCIe card installed with AES16 in a TB3 expansion chassis and a LT-TB3 LSlot interface installed in Hilo …Yes?
I don’t see that you have Hilo locally connected via TB3… We are seeing the AES16 interface and the Aggregate Device…
The bold settings that I’ve highlighted are your current settings and you should change these…
An obvious one and apologies if you have already done so but I assume you installed the macOS Core Audio driver V2 on the Mac Studio which was released on 15th January 2024? States that it fixes some issues with Ventura and Sonoma?
If you are right, good find 
Yes, Agoldnear, you have it correct with regard to my LS/LT cards.
Sure, here’s the debug report with the Hilo set as the Preferred Device. I also set the DSD gain to 0db and Bridge to 192KHz and 0.5sec (I also tried 1.5 and 5 and got crackling with any variation.)

Yes, I installed the Lynx update almost a week ago. Made no difference.
You seems pretty good to try every solutions, must be mac m3 bug with Origin… France monday morning is coming, not yet
Oh no, i see @Djm1960 coming with no bug with m3
I agree your latest settings look OK to me. I would in advance of Audirvana resuming work on Monday create a log file (settings, my account, help section “start log session”) when you have the issues and note the time when your track truncation issues and sound artefacts occur.
It will give them all the information needed to try and resolve your issue.
Well, some level of progress made: disabling multichannel output (DAC settings) and limiting the output freq to 192KHz (Bridge settings) has resulted in NO POPS* for tonight’s listening session including 44.1/48/88.2/96 and 192KHz files. This is with Upsampling disabled and output via Lynx AES16 into the Hilo for SRC at the hardware level.
Thanks all for your thoughts!
*Still get sporadic pops, though, when playing a 176.4KHz file and crackles when DSD128 file via PCM. EDIT: I reverted to v2.2.3 of Origin and the DSD128 crackles is gone. Guess will need to source v2.3, v2.4 and v2.5.0 to see when the issue started.
I think having Integer Mode enabled is a problem if Audirvana does not properly handle the low-level functions of Hilo via TB3 or the AES16 bridge and limiting the sample-rate to 24 bit may be more compatible with Hilo and the AES16 bridge.
You are not playing a DSD128 file via DoP 1.1 because the Hilo doesn’t support DSD over PCM (DoP) or DSD at all… You are decimating DSD128 to PCM and I’m fairly sure you can’t play decimated DSD128 because the DoP 1.1 PCM carrier sample-rate for 5.6MHz (DSD128) is 352.8kHz and Hilo supports PCM to 192kHz… So the best you can do is 2.8MHz (DSD64) because the DoP 1.0 PCM carrier sample-rate is 176.4kHz… I’m not certain what the default decimation target PCM sample-rate for DSD is in Audirvana, however, it would seem to be related to the DoP PCM carrier sample-rate… perhaps somebody can provide more insight here, since I’ve never needed to decimate DSD in Audirvana… I decimate any DSD files to PCM offline via the Bit Perfect ‘DSD Master’ sample-rate converter…
If you up-sample PCMxxx files to PCM 176.4kHz or 192kHz in Audirvana via r8Brain (I suggest you do, rather than the SRC in Hilo), your best choice will be ‘Power of Two’ up-sampling which will exploit the maximum sample-rate capabilities of Hilo.
Yeah, RunHomeSlow, I spoke too quickly. Reverting back to v2.2.3 solved the DSD128 issue. The the latest “old” version I have. Still possible to get v2.3, v2.4 and v2.5.0 off you?
Thanks!
Exactly!
The more extra settings that are implemented & engaged the more likely you will expose bugs.
Hello,
Here is the 3 version in my DropBox…
i didn’t kept 2.5 ? it might have a bug went it came out or it never existed 
I have put 2.3, 2.4, 2.5.2
So… is this an Origin + Lynx Studio platform firmware issue only? Because we see in the example above, this doesn’t seem to be a common issue for Audirvana Studio on a similar macOS platform… Was this a corrupted install of Origin? I use Audirvana Studio.
You’re awesome! So, yeah, v2.3.0 seems to be the stable one for my system. No DSD128 crackling and Volume Control works again.
Thanks for helping me prove I’m not crazy!
Well, likely not a Lynx Studio issue as reverting to v2.3.0 has eliminated the DSD128 crackling and Voice Control buzz blasting issues. I’ll try later to test if this version has Upsampling without artifacts and doesn’t truncate tracks.
But this kerfuffle was a blessing in disguise as it forced me to try the SRC path on the Hilo and the sonic improvement was tangible. So am doubting I would go back to R8Brain.
Understanding the parametric adjustments in r8Brain is essential to getting the best quality of output from the algorithm… As well as managing the gain structure of the signal through Audirvana after up-sampling of PCM files or decimation of DSD files to PCM.
Hi @swordpen,
I rode your thread on your issue and I’m glad an old version of the software solved your issue. However, as your audio system is not a mainstream one I would say, we will probably need to contact Lynx Studio to find out what is going on. Do you have a contact you might be willing to share with me at [email protected]?
Yes, I hear you, but it appears a daunting task. If using the SRC chip on the Hilo did not sound dramatically better, I would likely fiddle with the r8Brain settings. Ironic, because I started this thread to merely maintain a CONSISTENT audio quality, never dreaming that in the end I would be vastly improving it.
Thanks muchly for your sage advice and thoughts.
Now that I have had the time to test the Upsampling behaviour in v2.3.0, I can report that I am NOT getting any artifacts. It looks like you started optimising the DSD to PCM performance in v2.3.3 and that’s where it broke (for me). I need to get my hands on v2.3.2 now…
Any reason you don’t have the prior versions of the application available on the website? If that had been the case I would have tried reverting, found a version that was stable for my hardware, and not even created this “angry” thread.
Thanks!
