Please check out OS 8.6.6 which should solve S/PDIF glitches with some sampling rates on PROFILER Stage models as well as some other issues.
This OS is currently available as public beta. Rig Manager will recommend it, if "Beta" is selected in its Preferences. It can also be downloaded for USB flash drive upgrade here:
8.6.6 Relase solved S/PDIF glitches. KPA - Scarlett 48 kHz and 96 kHz sync works now (I hope its remain stable).

As to myself i will test it when "final" version available.

I have the same problem with FCB1010+Uno4Kemper->KPA Stage. It's works, but sometime KPA freeze when I change preset. I tried support, but no luck.
I downgraded to 8.5.8 (with USB stick), downgraded Rig Manager to 3.2.43, and restored rigs from backup (without this the KPA confused completly). Scarlett 8i6 3th gen now works well with 48 kHz (with 8.6.2 just the 44.1 kHz working flawless), With 8.5.8 and scarlett the 96 kHz still loosing sync, but I'm not going back to V7.
Display MoreHello,
I noticed that after installing 8.6.2.32267 in my Stage, I was getting harsh buzz with 48khz setting. 44.1khz seemed to be fine.
After reverting back to 8.5.8 that issue was no longer there.
I am using:
Focusrite Scarlett 6i6 2nd Gen
Stage spdif in Auto with both in/out cables connected to interface.
Answer from support:
"the developer team is working on that problem.
I suspect this issue will be fixed in the next OS Update.
Please have a little patience"
?
agreed but mentioning it in a thread isn’t the same as “reportng”.
Yes I know, but sometimes community solves quicker the problem, but also reported it. "Ticket ##KA00216762" is mine, maybe a good idea to reference everybody to this (if has the same problem). There are many complains about the same error in Facebook KPA groups. Some users report its working, but in the end: 1.using optical converter-interface, 2.using analog interface, 3. not Focusrite interface. Someone suggesting forget Focusrite (faulty), but it isn't true, because the error depend on KPA firmware version.
Have you reported this directly to support? They need to know if there is a bug so they can fix it.
Ok, I reported it, but its a recurring issue as I wrote, and 3 other people reported just in this thread.

I'm tried everything withous success, so reverted back to 8.5.8, now it's working again at 48 kHz. 
Hi works @96khz, i use a spdif to optical /converter
Thanx! Maybe this is the reason why works for you. Unfortunatelly Scalett 8i6 only has coaxial input. After all it's KPA bug because getting more unstable from version to version.
With UAD Apollo Twin it works fine here @48khz
Ooops ... one more question. As far as I know (maybe wrong) Apollo Twin has only one Optical input, how do you connect it to coaxial KPA?
With UAD Apollo Twin it works fine here @48khz
I'm curious 
Can you try with 96kHz? Mac or Windows (I'm using Macbook pro)?
Hello,
I have the same problem here. I'm using Focusrite Scarlett 8i6 3th Gen and KPA stage. With ver 7 firmware it's works with 96kHz (sometimes lost sync but works). Before 8.6.2 (-> 8.5.8) its works with 48 kHz, stable and clear. Now (8.6.2) only the 44.1 kHz usable without lost sync/buzzing sound. Tried with both clock source method (Scarlet or KPA), and 3 different pair of quality SPDIF coax cable.
Thank you very mutch.
Hello,
I considering to buy a spare mains cable (hate to unplug/pack, and there is a chance to leave it somewhere). The original has some builtin filter, so I afraid its necessary. Where can I buy similar (EU) one?
