Audiofuse Rev2 no power on, "A" button constant flash (Read 3904 times)

i’ve submitted a ticket and unfortunately the rep chose to ignore the symptoms and instead gave me the boilerplate on how to optimize my system for audio.

problem1: system will not boot when audiofuse rev2 is connected.
problem2: if connected after boot the audiofuse rev2 is not detected.
problem3: (the dead giveaway) “A” button constantly flashes and headphones release intermittent on\off relay sounds.

here’s a thread with 3,904 views, and several people saying they have the same issue.

the last one ends:>

Better contact their support as soon as possible. They are very slow and will take 3 days just to get back to you. Many more for any type of ongoing conversation. Hope you don’t have a studio that relies on this unit because Arturia support is not in a hurry.

it is disappointing to be treated this way. certainly this experience will make me think twice before purchasing any other arturia hardware.

Hello.

Wow sorry, it is a good thing that you came back on our new forum.

I’ve seen on the original post that one of the solution was:

  1. Plug PSU while holding “A” button - it boots on emergency firmware - DID NOT HELP

In fact, afetr doing that, you’ll need to update the firmware using the AFCC.

When the device led blink like this, it is because it’s firmware is corrupted or something. Putting the device in emergency firmware will only enable to load a new uncorupted firmware into the device.

So please try to:

  1. Plug USB
  2. Plug PSU while holding “A” button
  3. Launch AFCC
  4. Go in the Firmware Update settings panel and update the FW either from server or by downloading the latest firmware

Hopefully the AudioFuse will be updated without issue and it should work again.

I hope this will works for you !

Cheers !

thanks for this info. i will try it, but i have been working with sweetwater tech support and i believe the issue goes beyond a firmware update.

aside from preventing my main system from booting (hangs on power on, no dell logo, system flashes leds yellow. system boots fine when the device is not connected), this audiofuse gets pretty hot at times, beyond what i would consider ‘normal’.

do you have a list of authorized arturia service centers in the united states?

i will see if i can do the firmware update and if that corrects any of the issues.

here’s another thread, 2,654 views, three different users all describing a similar problem:

the problem turned out to be the usb socket.

although it accepts the cable (multiple cables tested) and holds it securely, a light bump on the wire causes the unit to disconnect or the led’s to flash.

there is no visual sign of damage.

perhaps some of the other users with this issue have a similar cause, i only noticed when i was experimenting with different computers/cables and had the power supply disconnected.

if i position the unit carefully and make sure the usb cable is undisturbed, the unit works on both of my music systems, without the need to update the firmware or optimize windows for music processing. as is happens, the firmware on the unit is up to date anyway.

Hi @kiimyo and thanks for updating us on your situation, GREAT to see it’s resolved now.

Your post is a great example of why we ask people to thoroughly check their USB cables and sockets and to have at least a few spare USB cables.

:+1: :sunglasses: :+1:

I confirm using cables other than the one provided rarely work flawlessly.

I don’t know why Audiofuse is so sentitive to USB cable, but I can confirm it is.

no one from arturia ever suggested checking the cable or socket.

going thru the original tech support email, neither are mentioned.

what i was told to do instead:

  1. disable audiofuse exclusive mode
  2. ensure all applications are actually defined to output sounds through the audiofuse
  3. set asio to safe mode
  4. optimize my system for audio
  5. install asio4all
  6. update or replace my network adapter

when the symptom is a system hang before windows loads when the audiofuse is attached, none of the above are likely causes.

i have two cables which ‘work’, one is the original.

and as you say, i also have two or three others which don’t work.

perhaps those are power only.

in any case, it may be that the socket is the root cause of this issue.

HI @kiimyo

Myself and one or two others on here are ‘External Moderators’, we do not actually work for Arturia.

I know that myself and at least one other Mod will bring this up very early in posts such as this as it’s a case of looking at what might fail most often.
I think Arturia Support possibly assume that people have gone through ‘the usual’ fault finding procedures before contacting them maybe?
Over time it’s become apparent that there are A LOT of people that will use one USB cable on multiple devices, which isn’t really a good idea, particularly if they’re being swapped out fairly often… i’m not suggesting this is the case for you personally, merely that it’s a fairly common situation that crops up fairly regularly here and on other forums.

I generally advise people to treat things like USB cables as ‘consumables’ in that they’re often the weakest link in the chain and usually the cheaper they are and the more times they’re plugged and unplugged; the more likely they are to fail.
The cables themselves are copper wire and copper is very strange stuff, it’s both malleable and ductile; to a point… you can only bend copper so many times before it exhibits a strange property where it will become hard and brittle and eventually snap.
This is why electrical cables are usually made of more than one conductor (wire), so when one fails there are multiple others that will continue to function… until they all fail at some point if not looked after correctly.

This is one of the things i’m trying to get to be made ‘sticky’ in the forum as it’s such a common ‘issue’.

HTH!

thank you for explaining your position here, and thanks for providing this service.

there are definitely usb cables i would describe as ‘consumable’ but the one arturia provided is very sturdy, and i’ve only ever used it with the audiofuse. it looks close to brand new:

a couple of more things for those experiencing similar issues - this is what my jack looks like, although it is clearly the cause of the issue, there isn’t any sign of damage.

i must have damaged it somehow, as the audiofuse worked fine for 4-5 months prior to sitting in a drawer for most of this year.

this is video showing the flickering leds when the cable is wiggled:

HI @kiimyo and many thanks for posting the pics and video.
I noticed there appears to be some damage on the USB port, if you zoom in to the top left hand pic it’s pretty easy to see, i’ve highlighted it below.

I don’t think this particular bit of damage is the cause of the bad connectivity as it’s not one of the conductors, they’re the five copper ‘bars’ in the middle of the pic; but it does suggest there could be further damage inside the unit.
There is also quite a lot of detritus around all of the sockets which won’t help with connectivity either.
You could try some 99.99% isopropanol which comes in a spray can form, by spraying it into the sockets and leaving for 24 hrs to fully evaporate and then try again.

My own feelings though are that there’s likely to be some damage on the inside of the unit, most likely a crack on a circuit board, if the USB port is surface mounted, or a connecting wire is broken and intermittently connecting somehow…

If you’re confident enough, which i think you might not be from your posts, you could open the unit if it’s out of warranty and look for yourself.
Perhaps a better option would be to see if you can find a local electronics repair specialist and get them to have a look, it really does sound like a ‘mechanical’ issue rather than ‘system’ related. It shouldn’t be an expensive fix either.

Alternatively you could log in to your account to contact Arturia support to see if it could be shipped to them for repair?

HTH!

i have submitted this info to arturia support.

if it turns out not to be covered i’ll open it up and look inside.

i tried to wiggle the metal portion of the socket, and also the ‘tongue’ with the conductors, neither seems loose in any way.

i’m having a bit of difficulty seeing the damage you describe. when i inspect the upper right corner of the socket i don’t see any difference between it and the upper left corner.

arturia returned the unit to me untouched, with a new cable.

it continues to malfunction, exactly as before. tested on two different computers.

i want to love arturia. i am half-french, their vst’s work nicely with my setup.

but this type of treatment is intolerable. it’s like cablevision-level service.
