3 Steps: Micro iDSD Firmware Upgrade
1. Ensure you have the latest iFi Windows Driver (v2.20) from here: http://ifi-audio.com/download/
2. Go here: http://ifi-audio.com/micro-idsd-ifi-xmos-firmware/. And save the firmware file “idsdv406.bin” to a folder of your choice (eg. Downloads)
3. Connect the MICRO iDSD to a Windows computer (OS X is not possible).
After this upgrade:
Win users (DoP)
With JRMC, the upstream “pop” issue from the source is virtually non-existent. With Foobar2K, there is still some residual “pop” hence we recommend JRMC until F2K catches up.
OS X users (DoP)
Using Audirvana, the upstream “pop” issue from the source is much reduced.
iPhone/iPad users (DoP)
With Onkyo HF player, the “pop” issue has gone. With Hibiki, there is still a residual “pop”.
Step 1: Run the upgrade program
It is NOT possible to double-click on the “idsdv406.bin” (it will NOT autorun).
Located here: C: Program Files>iFi>USB_HD_Audio_Driver
Step 2: Load the firmware file
Load the firmware file “idsd_v406.bin” by pressing the “Browse…” button.
Step 3: Upgrading the firmware
Upgrade the firmware by clicking “Start”.
When it is done, it will say “Firmware upgrade finished successfully.”
After the upgrade, please unplug the micro iDSD from your computer and completely power OFF the micro iDSD before first use.
Note： On some computers, one needs to perform the upgrade process twice for the upgrade to be successful. After the first go, the firmware version may still report it has the original version, in which case, press “Start” again to perform another upgrade and the firmware version should be correctly upgraded to v4.06. sometimes it just takes two attempts)
