Ok, count me as another one with screeching sound. I also got the following popup with in 45 seconds of the first song under win7 what popup would that be, nothing's posted?

He's saying that he had the screeching noise popup within 45 seconds. GeeboYou mentioned you didn't have problems with USB audio. Were you using a bit-perfect player like WASAPI mode?

My XDA-2 arrived yesterday. Both my Mac's - 2008 unibody Macbook and 2012 Air - are emitting strange ringing sound every 30-45 second I used iTunes and USB connection. Here is one test. Connect your high speed USB device, e.g. a hard disk using your USB cable. If hi-speed mode (480 Mbps instead of 12 Mbps, the old USB 1 standard) fails, it is a bad digital cable not compliant with USB 2 standards. The old USB standards do not let anything above 24/96 pass especially if the cable is of any substantive length.

So is there any word from Emotiva on this? Any word on a firmware update? On the XDA-1 I had to send my unit back to them to get a firmware update.

Were you using a bit-perfect player like WASAPI mode? I was using Foobar with the Wasapi plugin. I am using a port on my laptop that is a combo eSata/USB2 port. Windows 7 64 bit. But I was getting a static type sound for a second or two whenever interupting playback by selecting another song. When it cleared up it was fine until I interupted playback again. Charlie7 said he got the same with Foobar but not with JRiver.

I just listened to an entire Diana Krall CD from HDTracks with a bit rate of 96khZ and not a single glitch. I am using a 3 foot long USB cable. It sounds exactly the same as playback of the same CD from the Flacs on my hard drive connected to the Oppo 93. As I said before, I get a short static sound or stutter if and only if I interrupt playback and not every time. I think it has something to do with the buffer in Foobar. The sound is not very loud and is of shorter duration when using WASAPI push instead of WASAPI event. I don't get this when letting a CD just play through.

What Sorbe said with the popup. I am done playing with USB on the DAC with both Win7 (screeching sound) and Linux syste (DAC is recognized but no sound).

I would be highly surprised if there is anything wrong with the XDA-2 hardware. From everything I've seen here (and experienced/troubleshooted myself), I'm nearly convinced these problems point to a driver issue. This applies to the built-in Mac drivers as well as the custom Windows drivers. As far as I can tell, the hardware itself is solid. The audio reproduction via USB sounds perfect during the short durations of normality and in between the screeching, distortion, and ringing.

Right unless there's some issue with the ASRC circuitry messing up timing even when disabled or the way it locks onto a signal hardware wise. But I'm inclined to think it's more likely driver issues.

goat, I will follow-up on this tomorrow. I now own three 24/88.2 albums just purchased yesterday. My mini optical adapter arrives tomorrow, so I can test the 88.2 files with Decibel for you via the Mac optical out. We'll see what kind of strangeness occurs. Awesome! Thanks for doing this. I have been enjoying the XDA-2 with the TOSLINK outputs...even with the files being downsampled. I just wonder what I am missing if I could get the actual sampling rate with the USB connection (probably not a whole lot, really...but I hope this issue gets resolved). Thanks for doing this! OK, I got my mini optical adapter on Friday so I can now do optical out on the Mac. As promised, here are the results of my test: Using the built-in optical output on my MacBook Pro, I was able stream 24/88.2 files from Decibel to the XDA-2 at their native bit-rate with no down-sampling issues. Here are the settings I used: Audio MIDI Setup (Built-in Output)Source: Digital Out Format: 96000.0 Hz / 2ch-24bit Integer Decibel PreferencesOutput Device: Built-in Output (checked) Obtain exclusive access (checked) Adjust sample rate for best quality (sets device sample rate to match that of the playing track) (checked) Insert silence between sample rate changes (checked) Load files in memory Sample Rate Converter: Maximum quality (N/A) I tried 5 different tracks for each of the follow sample rates: 16/44.1 24/88.2 24/96 All of these files displayed the correct sample rate on the XDA-2. Because the optical output is limited to 24/96, I was not able to play back my 24/176.4 files. These were down-sampled to 24/88.2 just fine and displayed 88.2 on the XDA-2 front panel. With USB, I can play these bit-perfect, although I have to deal with the squealing. To be quite honest, I have only four tracks at 24/176.4 and zero tracks at 24/192. For now, it's not a big deal. It appears that some newer Macs support 24/192 from the optical output. Let me know if you want me to try or check anything else.

Here's what really makes me nervous: One of the XDA-2 symptoms repros on all platforms (Windows, MAC, Linux, other non-Emotiva CMedia based audio devices) and that is the "screeching". Since that happens on all of them, it cannot be just a device driver issue, the screeching has to be either a hardware flaw or correctable in firmware. Either way, Emotiva/CMedia cannot just post new Windows drivers and fix it.
The XDA-2 will need to have new firmware flashed (factory?) _or_ it will need to have chips replaced.

Please note, not necessarily, have you tried different cables ? I learned the hard way when trying to update my Harmony remote. Plugged it in to the computer and the Harmony (USB) and it showed they saw each other but no information would move from the computer to the remote. I could not figure it out. One day by accident, I grabbed a new cable, plugged it in a voila, it worked. I have had this problem with USB and computer audio, if the cable is not right, or if the usb slot you use on the computer has other electronices that run before it, you may get interruptions or other bad information. Go to device manager, USB and check to see if anything is inline with the port. If so use a different port. We should not automatically assume the equipment is bad. Also, Regardless of how new your computer (and USB controller) is, there is one cardinal rule — for Class 2 Audio most D/A converters cannot share a USB controller with any other devices. Be is antivirus software or ...well anything. It could cause drop outs and noise while the computer tries to do other things.

Hi guy's, Just a quick note to everyone...
We are quite confident in the XDA-2 hardware. This is not the issue.
We are working closely with C-Media to get the the root cause of this noise issue.
I apologize for the inconvenience, but we will have it addressed shortly and as always, Emotiva stands behind our products and your satisfaction.
Please allow us a few days to address this with C-Media and we'll get you sorted out.
We will extend your return privilege on the XDA-2 until this issue is resolved. I'll make an official announcement to this effect on the XDA-2 page and on this forum. In the unlikely event your unit needs to be physically updated, we'll arrange for an exchange of your current unit at no charge to you.
My apologies for the inconvenience. The XDA-2 is a fantastic DAC, and we will not rest until this problem is solved. Cheers, Big Dan

I am going to try mucking around with Linux later today and see if I can make it work with a stripped down version and see if Linux has the same issues.

Dan, Thank You for your comment and clarification on Sales/Support Policy with the XDA-2. I am interested in purchasing one of these now. I was going to ask you folks what your repair/exchange policy was with respect to this issue. You preempted my Post & Question re: support with your response here. Thanks Much!

Is It possible to make this the Official Thread on this topic so that we can better monitor all users comments and experiences with respect to this issue and to track possible resolutions both from both end-users and EMO etc?
Thanks!
HL
