I have the same problem with the U5 (it turns on with a warm-up hair dryer). Can you tell me if it is possible to solve the problem of U5 in the same way by soldering the capacitors?

Thank you! Because of this video, I could fix my Xonar U7. The soldering on my U7 was rather bad so i could simply take these off the board with a tweezer and a little force. Works flawlessly again!

Just removed the left capacitor and it now starts instantly again. Before that, i tried to plug it in on different USB ports on my mainboard. Some worked, some didn't. It seemed like the newer Usb Ports with Usb 3.1 worked while older versions of Usb didn't. Maybe this information helps others.

Chinese also make a fake Keysight GPIB-USB adapter complete with Keysight CD (who knows what spyware you are getting from it). Everyone of those sold on eBay as new is a fake. Mine broke down in less than a year. You get what you pay for. The real Keysight adapter has deep knurling on the tie down screws.

Fake does not mean it doesn't work. Problem with many fake devices is that they might work great but then there are some edge cases where you spend countless hours troubleshooting only to realise it is caused by the device being fake.

National Instruments (NI) has been changing its drivers to recognize fake items and won't communicate with them. A machine with the old drivers will work fine so long as you never accidentally update them. A new installation however is a PITA to get working with fake hardware, as NI hides the old versions of the drivers; iirc you have to search for a hidden legacy installer that can see those versions on the NI servers.

If you integrated the fake one then sold your system to your customer and commit that you are using the high quality GPIB-USB from NI, you are doing wrong. If you told the customer that you are using the fake one to build the system and your customer is okay with that, there is nothing to concern.

It is risky. I have a customer who was using fake one for production. It was running great in the beginning, but later many systems got troubles. At that time, no one could help. Using fake one is putting users into a risky situation. I would rather choose used but fake.

I added a 3.3k ohm resistor between pin 1 (oscillator drive signal) of the CM6632 chip and ground, seems reliable for now even when chilled with freeze spray. I think the transistor in the chip is really weak and unable to pull the line low so this gives it a hand to cross the low threshold.

The Mk2 uses the CM6632AX chip instead of just CM6632A, I guess it's the same chip but with the issue fixed. And Asus decides that's worth calling it "Mk2", lol

I've actually done some digging on the problem on another product based on the same chip and concluded that it is indeed the main chip. Nothing really to do about it. It seems like the only solution is swapping the chip. But as always thy are also really hard to get.

Mine sadly stopped working again after some time. I've done a lot of hacking, changed the crystal, modified the load capacitors, removed the resistor parallel with each CLK pin, using external generator for clock, measuring different power rails and haven't found anything that would fix it. I even went as far as contacting Asus. Ofc companies don't give a damn and wont tell the actual difference between the "MK1" and MK2 I managed to get to a state where i can put the soundcard into the fridge for 10 min and reproduces the issue What I've concluded doing my debugging is it is indeed related to the IC and not the crystal. If heating either of the top edge corners of the IC the circuit will start operating again but not as easy to reproduce if heating in the bottom of the IC Buying a new IC is just so expensive so i sadly is out of ideas and might give up on mine. I've gone though multiple pictures of the MK2 and the old version and have not been able to find any obvious difference

Hello. I have actually also faced issues with my soundcard not working again after some time. After 7 months it started with not wanting to work unless i replugged my USB. I actually was considering replacing the crystal but before doing so i was going to try measuring the frequency as i was curious how much it had drifted

I tried this, removed both of them with force, its not broken further but its still blinking... I'm using hair drier to heat it up to function again. I may buy U7's mkii version (I hope this problem does not exist on that)... after all these years no usb multichannel dac out there to top this on price/performance. edit: btw mine has passed the method of just touching on quartz to function several years ago.. now it needs hot air to work. maybe thats why this method didnt work on my device.

Hmm This might actually explain a bit about the issue, that the capacitive load might not be the issue but rather that the crystal actually is poop quality and have to be replaced in order to fix it for some people. Sucks to hear that it was not resolved by using my method. My initial thought of why the hotair works is that the crystal frequency have drifted over the years and as those crystals are sensitive to the room temperature then by blowing hot air onto the crystal it changes the frequency which causes it to start up.
