Subject: AES16e not recognized in Windows 7
Date Posted: December/10/2015 at 5:06pm
Recently purchased a AES16e to replace my old AES16-SRC.  Installed the card in a PCIe x1 slot and it worked but it seemed little buggy (ASIO/driver seemed unstable) and the latency did not improve as I assumed it would.  Updated the driver to 23, not much difference.  Went to update the firmware and it failed, always timed out during the verify stage.  Tried it with moving the eprom jumper to #1, did not work that way either, same failure message.  Put the jumper back to #2, then tried the AES16e in a 16xPCIe slot, Windows 7 did not recognize it.  Put it back in the PCIe slot now it's not recognized there either, so the card seems unusable now.  I put back my old AES16 SRC so I can still work.  Seems to be a hardware problem, possibly this motherboard or the card itself?  System works pretty well with the older card but latency has always been worse than I expected with this machine, which is only a year old.

My system:

Win 7 SP1 64 bit
ASUS Z87-A motherboard w/Haswell i7 @3.4  -- latest drivers and firmware installed
16mb DDR1333 RAM

If the firmware update failed, then Prom 2 will not be usable until the card gets re-programmed. I would keep it set to Prom 1 and try a different PCIe slot and, if necessary, a different computer. If it appears at Prom 1, then update the firmware again. If the firmware update is successful, then you would move the jumper back to prom 2. 

As to latency, often the AES16e can be set one buffer size lower than the AES16. If that is not the case it may have something to do with the motherboard's PCIe support. Let's evaluate that after we get the card back online.

Thanks much Paul.  Is it OK to put the card into other slots such as PCIe x16 slot, etc?

OK, that  seems to have fixed the problem! The card is now recognized and working thanks again.

I do have a couple of other questions however, the question above regarding the PCIx16 slots, will putting the card in those slots help with latency? With the new drivers and firmware Lynx is claiming very low latency is achievable.  I've tweaked my system quite a bit but am still unable to reliably use buffer settings smaller than 256, and it is more stable at 512.  This is with Samplitude ProX software, the project has 24+ tracks with a mix of 64 and 32 bit plugins.

A 16x slot should have nothing to do with achievable latency. 
If your DAW has a mixture of 32 and 64 bit plug-ins, that can be the source of the bottleneck. The wrappers that allow a 32-bit plug to work in a 64-bit OS are notoriously problematic. 

What sample rate are you running at when you need to use a 512 buffer?

Most of the time the projects are 88.2.  Yes I figured it might be the plugins.  I'm going to attempt to switch to 64-bit ones whenever possible.

I notice if it's below 512, there is some stuttering and dropped ASIO buffers if I'm scrolling up and down quickly in the DAW to look at different tracks.  I assumed this might be a graphics issue so I added a cheap graphics card to the system but it didn't seem to help.  I'm using Samplitude and it's possible that is part of the problem(?) so I'm looking into Reaper as an alternative.

What firmware version are you currently using?  This information is in Lynx Mixer > About Lynx Mixer.

Firmware is 14.0

Check your SpeedStep, C1E, C3, C6 in your BIOS and make sure they are all set to OFF or NO.  I have an ASUS Z87 motherboard as well, and I needed to turn all of those off to get the best performance for audio applications.  That let me get my buffer size down to below 1ms with a pretty heavy CPU load.

Thanks much David for your help.

Speedstep is disabled, but I'm not sure what the other functions are that you mentioned, C1E, C3 and C6?

F2 on Boot to go into the BIOS
Advanced Mode (F7) > OK
Advanced / CPU Configuration / CPU Power Management

EIST: Disabled    (This is SpeedStep)
C States: Disabled        (This is C1E, C3 and C6)

Hi David, yes I did find the disable C state switch.  Wow that made a huge difference -- I'm now able to set the buffers at 64 or 128.  Thanks so much.

I was also curious about the BIOS regarding the CPU cores synchronization, do you have preferred settings for that?  At the moment I have that stuff turned off or set to "auto", but there are settings for syncing all the cores or syncing individual cores.

"A sleeping processor produces no audio."  You can quote me on that one...

We haven't needed to change any of the core synchronization settings.
