do we need to set the PCI Latency in a Mac Pro? If we need to set after the driver is successfully installed, how to set it in a Mac Pro?
 

(This question may not be related with my current problems.)


Did you install PCI UAD-1 cards using this method? If so, and they worked, it very well may be a Lynx driver problem.

I am in no way saying anything bad about Lynx, as they are still my favorite audio interface manufacturer even though I had to go with an Apogee when I upgraded my Mac from a G5 to a Pro. I wish I would have had the $ to purchase a newer Lynx Interface, but I had to settle for what I thought was the next best for the price. Also, the support from Lynx is better than any tech company I have ever dealt with in my life, even UA. This company purchased a G5 with my specs just to troubleshoot a problem I had. Thanks Lynx!

After I installed the driver again and reboot, I tried to load Lynx Mixer.app in Applications. Then the message showed again : 'Cannot find a LynxTWO/L22/AES16 card'
As I look over the Console Messages, I found the following:

05/12/2010 11:17:27 AM     com.apple.SystemStarter[44]     >>> LynxTWO Restore Settings

05/12/2010 11:17:31 AM     com.apple.launchd.peruser.501[107]     (com.apple.ReportCrash) Falling back to default Mach exception handler. Could not find: com.apple.ReportCrash.Self

05/12/2010 11:20:02 AM     [0x0-0xf00f].com.LynxStudio.LynxMixer[160]     Unable to find any Auroras via Mixer Driver

What can we conclude from these?

That is the console.log.  You need to look at the kernel.log.

Where is kernel.log? You mentioned Applications > Utilities > Console before.
I can't find any kernel.log in Applications > Utilities > Console as well as Applications > Utilities.
Even I searched kernel.log in Finder but got no result. Please tell me where to find it as I am merely a freshman of MacOS. Thanks

Most likely the PCI configuration registers have been programmed incorrectly.  This is up the the BIOS (EFI) to do, and clearly it is being prevented from doing so properly.  Since this is a completely non-standard device and a non-standard way of hooking it up, it isn't surprising that it doesn't work.  There isn't much that can be done about it.
Thank you,

Do you imply that the coming 64bit driver will also be unable to work for my card on Mac Pro? Did I choose a wrong PCI-E to PCI bridge expansion chassis card? What should I use to replace it? Or should I modify some specific settings (e.g. BIOS, EFI,....) of my Mac Pro to cater for my LynxTWO?
Do you mean that my LynxTWO will never be able to use in my Mac Pro? However the FAQ of LynxTWO in this site told that we should be able to use this card on a Mac Pro. Frankly speaking, I bought this Mac Pro for my LynxTWO together with some pro core audio softwares after I read the FAQ. How can I accept that we can't installed on it?

Quote Did I choose a wrong PCI-E to PCI bridge expansion chassis card?
Since it doesn't work, yes.
Quote What should I use to replace it?
The Magma is the only PCI Express to PCI expansion chassis we have tested that works.  Even the Magma has some issues with the clock chip, so you must be careful to get one that has the correct chip.  We have tested other manufacturers audio cards in the same array of expansion chassis as our card.  The results were the same for those cards as well.  Only the Magma worked.

When someone says that something like a very high-end and pro Magma chassis works, that does not mean that some weird random PCI-E to PCI adapter card (not a chassis) will work.

What you have is NOT a problem with the Lynx or the Mac Pro. It's a problem with a no-name device that costs 120 yuan or 120hk$ (i can't read chinese) ($15.50 US or $18.05 respectively) with a $7 to $8 US no-name cable.

A Magma setup costs (MSRP) $399 US for the PCI-E card, and $1,099.00 to $2,099.00 for the chassis. That's 16,605 yuan or 19,392 HK$.

Do you see a difference? The Magma costs 138 to 161 times more than your completely non-standard cheap, no-name adapter card.

Do not blame Dave, Lynx, your LynxTWO, or your Mac because you bought a product that is crap. On the link that you provided it doesn't even mention OS-X, it only says "support：Windows2000/NT/2003/XP/Vista/Linux".

Accept that you have the wrong PCI-E to PCI adapter, and get a good one.

Hi David,
 
I have trouble with my LynxTWO now.
After I have tested my LynxTWO in my MacPro, I reinstalled into my previous PC with XP (32bit). I found something special with those analog input channes. As I opened the Mixer Window, I found some signals visible in Analog input channels 1, 3 and 5. Those signals are not fixed in level. However I hadn't connect it with the external cable. I switched off my computer, unplugged my card and installed again. Channels 3 and 5 still showed variable signals. I neglected them and connected with the external cable and the problem still went on. I tried to unplug and reinstall the card. The signal of channel 5 disappeared but that of channel 4 and 6 would come out. As I changed manually the sampling rate from originally 22.5kHz to 48kHz, 96kHz. The amount of those signals would reduce for about a half but still were visible. As I tried to route those signals to an output channel, I heard some crackling sound from the channel.
On the other hand, I found another special thing with my analog input channel 2. As I feed low level or normal level of sound into it, its meter showed nothing. It would show suddenly a rather large variable signal if I increased the amount of input sound gradually till a certain large level.
 
What's wrong with my sound card? Its firmware is the latest and the driver is Build 18b. I updated the driver to 18c but the problems still go on. The sound card worked normally before my test in the MacPro. What should I do?
