Going back a few years, but wasn't the TI chipset identified as the one to have for Sonar and Firewire? I seem to recall a thread where it was listed as a best practice.


The DAW is irrelevant, it's the hardware it connects to. VIA has worked perfectly fine until Win10. Either Focusrite or VIA driver to blame.

The PDF posted here gives a list of Focusrite compatible chipsets

All Sonar is concerned about is a good ASIO driver.

Firewire was originally adopted as a connection favored by movie makers and used to attach movie gear.
It tended to be more adopted by the Apple users, since Apple invented it.
Apple wanted a licensing fee for each interface, so Intel came out with USB alternatives.
Firewire and now Thunderbolt always stayed a step ahead of USB, but now with USB 3.1, we probably have a break-even point again.
 
However, it will still be a while before we see newer USB devices.
 
Firewire is probably considered dead nowadays as few pieces of newer equipment support it. And Thunderbolt is very expensive, power hungry and thermally active. All the connectors are active. USB is far more universal and the newest USB 3.1 stuff with that great new connector will probably become the de-facto standard in years to come.
 
Back in the XP days, I had a special PCI card that had Firewire 400 and 800 ports because all my external drives were Firewire 800. (This was before e-SATA, which I use nowadays).
 
It did sometimes seem to be trial-and-error to find the right chipsets and drivers because some people had movie gear, others audio, and I had audio and hard drives.
 
These old debates always re-surface when problems come up, but I think the issue is one of just finding out what works for you. The specs haven't changed and all the parts are supposed to conform to the spec. And just when you get things working, some new update will come up and you have to re-tweak things again. That's become a major issue now with so many vendors adopting 'agile' programming techniques.
 
In the past, I found some versions of NVIDIA graphics updates interfered with interrupt latency and made my Firewire interface glitch. But that was quite some time ago. I still try to keep my video drivers up-to-date, even though they are mostly game updates. I do check things with latencymon after updates.
 
For Focusrite drivers, there is a Firewire latency setting (not really audio latency) that seems to apply to the firewire transactions and interrupts. Larger setting might make larger Firewire transactions and heavier interrupt times, while shorter latencies will use smaller chunks at more frequent intervals. At least that is my understanding.
 
I've found the 'Short' setting was inferior for me compared to the 'Medium' latency setting. I was able to load larger and more projects using that.
 
Most of my projects involve humongously complex Reaktor modules (which are single threaded), so I need all the performance per core that I can muster. My tests then are stressed that way - most bang per CPU, not most number of tracks total.

Focusrite emailed me today saying situation is still ongoing and they will be emailing me when it is fixed.

Apparent workaround.... Not tested.
 
Turn on Saffire.
Start Windows 10
Log in.
Restart Windows 10 (keeping Saffire on).

VIA Firewire chipsets have certainly NOT all worked fine with all audio interfaces up until Win10.
Ever tried to run an M-Audio FW1814 connected to a VIA chipset Firewire controller?  Don't bother, you won't be able to install the driver.
  • Some VIA Firewire chipsets work fine with certain audio interfaces (RME and MOTU are less fussy about controller)
  • Some VIA Firewire chipsets "work" in that you can play/record audio... but performance is poor compared to TI.
  • Other VIA Firewire chipsets result in complete instability (or just plain won't even allow install of audio interface)
 
It's rare, but even some TI chipset Firewire controllers are unreliable with certain audio interfaces.
  • Manhattan makes a TI chipset Firewire controller that doesn't work properly with the MOTU 896HD.  Ironically it works fine with the 8-Pre.
  • UA Apollo, Mackie, and Tascam units are particularly fussy about the specific TI chipset.
 
It's down to the specific combination of Firewire chipset and audio interface.

No issues with Win 7 and 8.x at all. Works great, I have had no issues ever until Win10.

The problem is just windows 10 (for the moment). Loads of other drivers are having problems under Windows 10 right now, so obviously it's software not hardware.

And as you see it's deemed perfectly compatible by Focusrite:
http://d3se566zfvnmhf.clo...%20Compatibility_0.pdf

"Chipset Incompatibilities: The FireWire chip controls all data being streamed to and from the FireWire port, and certain chips have been known to cause problems with connectivity. We would recommend using either a Texas Instruments or a VIA FireWire chipset to avoid any such issues."

I trust Focusrite with what they say, they are excellent esp with support. They will resolve this issue.

What I've seen posted in the last few years supports what Jim is saying.

And yet the manufacturer of this interface states (again):


"Chipset Incompatibilities: The FireWire chip controls all data being streamed to and from the FireWire port, and certain chips have been known to cause problems with connectivity. We would recommend using either a Texas Instruments or a VIA FireWire chipset to avoid any such issues."
 
If it's Jim vs Focusrite, I think I know who is likely to be correct here in the case of this interface.
 
And I've had no issues with Win 7 and 8.x and VIA - so forgive me for completely disagreeing in the case of Saffires here. There is a specific problem going on with Win 10 (Focusrite drivers or VIA drivers or even the OS itself) and Focusrite are on it. My interface continues to work on 8.1 so it's definitely software not the chip.
