I'm interested as well.

Unfortunately I won't be available tomorrow after all. I could do 18:00 and only stay one hour, if that works.

I'm cool with the 30th. I think we can save the date.

I managed to get it working :) I didn't do anything special actually. I just took it to take some high-magnification pictures using my USB Microscope, and then I checked for continuity across some of the Wolfson's pins, and then it started working. It might be the multimeter leads that...

Hi Guys! Another one with a no-sound problem right here! Here are some notes: 1. The GrubDAC is detected fine by Windows and shows up on playback devices. No instabilities. 2. The LED lights up. 3. 3.3V Test point shows stable ~3.29V. 4. 5V Across C5. 3.3V Across C1 & C15. I've reflowed U1...

I'm in as well! :)

Really late bump: Since then, I found a solution to the problem. Removing a 75 Ohm resistor under the coaxial input solved the problem. It was an impedance mismatch with the DI (probably with other transports as well, I can't recall if I checked that). I hope it will help others. :)

I see. Can you check your dac coaxial input impedance? If you have a multimeter, check the outer ring and the inner hole for resistance.

Does it make any sound? Does it play?

I have the Intel Z68 - top of the line high end chipset for the LGA1155.

My input: 1. Either with external power supply (battery) or usb power supply, I get blue screen. Cable contacts are perfect. 2. My computer power supply is Enermex Pro 82+ II 620W, which has lots of clean power and headroom. I'm directly connecting to back usb ports that can 100% deliver 500ma.

Are you talking about the DT880? Why do you think that?

You mean to check continuity? I can do that. What you did to the K75? it looks interesting. I have the FT-3 and the K42-11 combined.

1. Where is this 47k you are talking about? 2/3. I guess you'll have to order some TDA1543's to check.

Well, as far as I can tell it only affects ASIO, so you might just use ASIO4ALL for a while. I was quite right actually - I put back the transformer and then removed the 75R resistor. 96Khz still plays beautifully and the transformer (upgrade) is back. I think there a slight impedance...

I think the sharc has the spdif receiver integrated. Anyhow, I am now convinced the problem is not the spdif receiver. You see, when Ori from Oritek Audio upgraded the dac (from Zhaolu into Oritek) he put a transformer on the coax input as one of the upgrades, it should reduce jitter / upgrade...

I understand. What settings are you using? WASPI / KS / ASIO, and what are your selection for the output audio format? Kingwa says that the CS8416 is "hard to design" and different designs might actually not work. I hope this can be fixed through the drivers.

Wayne, he suggested a non-microphonic alternative for techflex as cable sleeving :)

1. Can you elaborate on the "plate choke" mod? 2. Can you test optical / coaxial input? 3. Try to remove the TDA1543 from their sockets and then put them back. 4. Remove all 7 TDA1543 so you have only one chip. Try different chips in different sockets.

1. Different computer? 2. Leave USB unconnected and check if coax input works.

I don't think it matters because you are using I2S so you're bypassing the receiver. :) Did you try Coax? I understand your DAC has the DSP-1 which uses the DIR9001 spdif receiver, the same as my Valab that works. So far (to my understanding): DIR9001 - OK ES9018 - OK CS8416 - BAD I don't...

I think the problem arises with certain spdi/f receivers inside the dacs. With my Valab NOS DAC I recall playing 24/96 with WASAPI fine. It has a DIR9001 receiver. My Oritek which doesn't work with the DI has a CS8416 receiver. Which dac's / receiver's do you have?

Since I switched to ASIO a few hours ago, I had about 12 blue screens on normal listening, also track loading and seeking is very slow. This method is unbearable. I had to switch back to WASAPI and listen to standard definition content.. there is no other option for me. When playing high...

It works fine.. extract it using 7zip. Guys, I still can't play 24/96 or 24/192 using my DAC, and I'm starting to think my DAC is absolutely fine and the problem is the DI. I get all sorts of weird crackling noises, and on current conveyer the signal actually locks (but with noises that subtly...

I can't play 24/96 with my Oritek which is a kind of absurd. It should support up to 24/192 playback.. I don't know what's going on. :(
