HoloAudio Drivers – Win7/8/8.1/10 v5.12.0 (this is the LAST driver for Win7/8/8.1 OS) 05-28-2021
Firmware for Gen2.1 USB ONLY (Post August20th 2021 dacs ONLY) “enhanced 3144” fixed_volume and variable volume – NOT for Gen2.0 USB – best paired with the new v5.27.0 windows drivers (HERE). (This firmware (fixed volume version) addresses a Bug with Linux OS where the volume is at 40-50%, this firmware will address that and apply volume at line level (this was not an issue with windows or mac) This firmware (fixed volume version) is STANDARD as of 11/29/2021 (optional variable volume firmware included but not recommended for most setups but may be ok for windows and mac)
*note: May DAC DAC does NOT need firmware update in some cases. L2 May and KTE May come shipped with 30.14 firmware (pre aug2021) and Gen2.0 Enhanced USB Module. (compatibility firmware), however if you need to use DSD1024 and PCM 1.536mhz than you would need to install 30.12 firmware which is less compatible with some devices. However the 30.12 firmware does support high res content with Intel Gen7,Gen8,Gen9, Gen10 type Intel boards and many AMD comparable motherboards are incompatible with this firmware. And some dedicated cards with Altera Chipsets. Please contact us about the Gen2.1 USB module if you have AMD CPU. Post Aug2021 KTE Spring3, L2 May and KTE May come shipped with Gen2.1 Enhanced USB Module. Between Gen2.0 and 2.1 there are no differences in sound quality, only added support for AMD CPU. Many users will not need this module, however if you have AMD CPU, contact us to discuss our swap out program and how you may qualify for this program.
these firmwares are also for other models – Cyan DSD or PCM, and Spring V1 or Spring V2. Please read instructions included carefully and entirely.
note: WIN7 users may have issue if you don’t have the most recent hotfix for SHA-256bit code signatures. By default Win7 only supports SHA-1 signatures, yet SHA-1 is obsolete and this hotfix is very important for security reasons. Win 8 and above have SHA-256bit by default. Some users reported these drivers not installing properly, so be sure your Win7 is up to date, or download the hotfix here (KB3033929) : https://support.microsoft.com/en-us/kb/3033929

NOTES for new 5.00 Driver (this is a major release with firmware update for each model, Spring2 (two versions), Spring1, Cyan.
* New usb driver, 5.00
* Spring2 new usb firmware 30.12 (significant improvement of USB performance, and recommended for those using Motherboard USB (intel/amd) this is only firmware that supports DSD1024 and PCM1.536Mhz (all dacs ship with 30.14 for compatibility reasons) but you can use this if you have a modern PC with Intel/Altera USB chipsets. It works with most Gen7, Gen8, Gen9 and Gen10 Intel boards and comparable AMD boards.
* Spring2 new usb firmware 30.14(only support up to pcm768k and dsd512 but is DEFAULT firmware since late 2020). This firmware can be worked with those ‘hifi’ PCIE usb cards (JCAT PCIE Femto (renasas chipset), Linear Technologies PCIE Femto card, Matrix Element/ElementH USB card (texas Instruments). it’s most compatible with most usb cards and usb controllers. Also compatible with some special USB fiber optic cables.
* Spring Version 1 – new usb firmware 21.16. This fixes the problem roon has mentioned before, which has problem while switching between 24bit and 16bit at same sample rate.
* Cyan PCM or DSD – new usb firmware 21.06. This fixes the problem roon has mentioned before, which has problem while switching between 24bit and 16bit at same sample rate.
All new firmware must have installed the new 4.67 USB driver first. and then copy the directory of the firmware contents into the driver folder… commonly found in programfiles/holoaudio/USB Audio Device Driver/W10_x64/
then run the file “holousbaudioDfu.exe”
BE SURE you copied the appropriate firmware for your dac.
V1 and V2 spring are very different.
take note dacs from late 2020 were shipped with version 30.14 are for those with either JCAT Femto PCI-E card (renasas chipset) or the Matrix Element or Element H card (texas instruments chipset)
these are LIMITED TO DSD512 and PCM768 at this time.
HIGH content resolution firmware – version 30.12 is for motherboard USB chipset which is commonly Intel base USB controller and should support DSD1024 and PCM1.536Mhz as stated above in overview.
Spring V1 firmware is only one choice and has no issue with Jcat or Matrix USB cards, so no worries here. both Spring V1 and Cyan have known issue with Roon where changing from 24bit and 16bit sample rate can cause a problem. this is now fixed and addressed in the new firmware update.
ALL these new firmware updates improve USB transfer eye pattern in a significant way! there is a significant reduction in emi noise during USB transfer, and this means theoretically improving sound quality. Measurements confirm whether one can hear the difference or not
