I just gave VA 4.2 2012 Beta a small test run and it seems to work much more smoothly than earlier versions.
I didn't give it a full test with tones yet, as I will do this later.

However, I could only get it to work in Win7.

I don't have any sound cards that will work in Win7 at this time except for what is on the motherboard.

I figured that I would give it a quick try before I wiped out my Win7 drive as I have switched every thing back to XP64 at the moment because I am tired of incompatibility issues I have with my older hardware and Multiplicity.

I guess I will have figure out a multi-boot system as I use linux as well and I have done it before, but it is a PIA to do sometimes.

Anyhow I did get VA4.2 2012 beta to lock up under one condition and is probably expected by doing a calibrate function using 0v and no signal was applied only using the noise floor of the onboard sound system.

Also I didn't have anything plugged into the input jack so they were probably shut off, as it does this in Win7, and is what could have caused it to get lost and lock up.
Let alone trying to calibrate to Zero.

I will give this another full test once I get my machine reconfigured with a Multiboot of the Three OS's that I normally use.

It sucks having to keep Win7 around as I just don't like it!!!

But this is not the only program I have run into with this problem of only working in Win7 these days.

Cheers !!!

With GRUB, it's easier to install Linux over an existing Windows installation. GRUB will automatically take over the BCD in Vista and higher, and the NBR in XP and lower. I had some driver issues with XP64, at any rate.

I don't think his program is designed to operate with no signal sample at all.

I would check to see what's going on in the bios; that everything is enabled or disabled that should be. When you get the sound card, I would disable the on-board, and enable the addon card.

Most onboard sound cards are lousy, and if you blow it up, it's gone forever.

Try the C-Media CMI8738. I'ts cheap and works perfectly with VA and W7. I prefer used cards because if they still work after all that time, they will probably last forever. One problem, however, may be corroded jacks on the card. I found colored ones 10 for $2.99.

Or you keep buying used ones for $5-$8 each until you find a perfect one. New, I would go with the ASUS Xonar DS as it is high quality and there is a fully-functional, Linux driver for it. It uses either of the PCI slot types (not PCIe), and is about $50. The DG is no good for Linux, as the driver is incomplete, last time I checked 1 year ago.

I also recommend an ASUS motherboard when you get around to it.

Dust buildup on the old mobo can cause "phantom" errors. These are not only more frustrating than finding an intermittent electrical connection, there are no solutions on the net for them (for there cannot be). In fact, I suspect many of these problems we see on the net (that have no good solutions) are in fact caused by phantom errors, or errors caused by mains spikes!

I noticed most people do not bother to acquire TVS protection.....nor does anyone clean their mobo...

I strongly urge you to use a USB sound device with 24-bit ADC and DAC, like the EMU 0204 or Quatasylum QA400, for example, if you are at all interested in high resolution analysis. Many of them will work in Win7 as well as XP.

I really can't see much diff between XP and 7 except for the underlying changes and driver changes, but then I'm a Mac user mostly, so the changes wouldn't stand out for me. But Win7 does let me easily dual-boot my hackintosh.

Speaking of sound cards, what happened to http://www.daqarta.com/dw_ggnn.htm

and the Syba no. SD-AUD20040 for DC measurement?

Has anyone tried it?

I was actually able to get on the forum today and re-download the files.
And I found that the 32 bit version does work in XP64 but the 64 bit version does not.

The card that I am using at the moment is a Gina24 and it has an ASIO driver.
It works great but I was not able to get the software into 24 bit mode as in past tests in fact this version stayed locked in 16bit mode.

I have been studying more about the USB interfaces and I will attempted such an interface as described on VA's home page only I will use some other A/D and D/A chips from either Analog Devices or LT.

I can't get the Gina24 or Creative's X-FI drivers to work in Win7 on my new machine because they are not recognized by the UEFI Bios that it has, as the cards predate it by many years.

I have read of others whom did get them to work but so far I have been unsuccessful.

I did however get VA to run the Gina24 in 192Khz Stable this time (maybe, I have not verified it yet) as VA would lock up with the earlier versions.
This time it ran without locking up even though it was locked 16 bit mode.
16 bit mode is fine for now until I get a proper interface built.

Not only do I want 24 bit precision, But I would like to be able to measure DC voltages as well and you can't do that with most sound cards.

At least I did get the new 32bit version working in XP64 for now, and, just having the software stable is 100% better than it was before.

Cheers !!!

I couldn't verify it to be running at 192Khz with my hardware although the software could be set that fast, I could only verify a 96Khz input sample rate and at best it would sample up to 44.1Khz flat.

However that is what my current card is specified at, 96Khz.

When I put it in 24bit mode the software stays running but I get no signal displayed from the card, setting it back into 16 bit mode the signal re-appears and is displayed correctly.

Normally the earlier versions would just lock up when any changes were made with those parameters on my system.

As I mentioned, I will do more testing on my newer machine with Win7 once I get it back running again as the on board sound system will do 192Khz, and, after I build my interface buffers into a permanent enclosure as well and start testing stuff again.

OMG!!

I just tried out the latest VA2014 and so far it looks really good!!!
It still doesn't pick up data from my Gina24 sound card in 24 bit mode but at least it doesn't crash when I set it to it.
Sometimes it will stop when switching modes but it does recover easily.

Here are some screen shots of a simple un-calibrated loopback test, The abnormal Green FFT trace may be due to a crappy cable.

I can't wait to start putting this new version through its paces!!!

You can find it here,

Download

Nice Job, and, Cheers to the developer!!!!

P.S. You have to use the 32bit version if you are using XP64.

Great to see some activity here. Installed perfectly on a 64 bit desktop. Looking forward to digging in this weekend. Thanks for the heads Up
