Have to admit I used to have drop-out issues fairly often. Got used to turning my Pulse Infinity off and on to make it work again. However those days are (hopefully) over. I recently got a new computer and therefore had to reload the software/drivers and haven't had an issue since. Seems like those bugs have been worked out (at least for my setup - Infinity & Windows 10). Cheers

The newest firmware is not completely bug free, seems it still have problems with sample rate switching, with one channel dropping out. It doesn't really bother me much I just use a different filter than closed form for 48khz pcm/dsd

Cork top added. It was an easy change before I create a wood top out of purpleheart or wenge.

I will go ahead and attach the latest firmware version for your unit in the email below. The online step-by-step procedure for updating your unit can be found here If the Pulse refuses to connect, try disconnecting the USB cable from the back of the Pulse, wait for about 3 seconds, then reconnect. The Pulse should then connect and update.
The MTX on the other hand cannot be updated from he field unfortunately. However, 2.0 was a very stable firmware and I can proudly tell you that from my experience with working alongside these dacs. Let me know if the MAIN firmware update resolves the issues you've been experiencing with your unit.

 
Hello everyone!
 
I just received the email and attached lasted firmware from LHLabs for my Pulse Dac. I will do such updating upon Im back my home (from my office now).
 
However, I really dont know the meaning of the sentence "The MTX on the other hand cannot be updated from he field unfortunately". Could you advise me what the MTX mean? I did google such but cannot find the meaning thereof.
 
Thanks & regards,

Believe they're talking about the firmware for the display, which shows up as MCU in the menu. For the original (V1) Pulse chassis the display firmware could only be changed at the factory. For the updated (V2) chassis they included a card slot to allow that part to be updated in the field as well. 
 
However, if someone know "MTX" as something different, please let me know.

MTX refers to the matrix display.
 
Only the newer Pulse 2.0 units are able to have their display board firmware flashed in the field (by you), the Pulse 1.0 units have a matrix display board that can only be firmware updated by LH Labs.

Curious about why 2.29 would work as I wouldn't expect LH Labs to have done 2.29 with a driver signature but not 3.26?  

 
Below is what they told me to do:
 
The new Windows 10 update has changed the way it accepts digitally signed drivers so if it doesn't like the way one of the drivers is signed, it will block it from being used with the computer. You will need to disable that feature and all should work then.   
Here is what I've found, "Many programs which use driver files do not have digital signature authentication, such as the phone drivers or other USB drivers. To receive verified certificates, manufacturers or developers have to pay Microsoft, and this makes lots of drivers are not accessible in Windows. To install the unsigned drivers on your computer and make them work properly, you need to disable driver signature enforcement." Link

Received a follow-up email they were able to recreate the problem and looking and updating the driver. They suggest staying with 2.29 for now.
