iConnectAUDIO4+ outputs stop playing audio and play electronic noise

Hi everybody!
While I'm waiting for iConnectivity support reply, I'd like to share a problem I've been experiencing for a while:
all iConnectAUDIO4+ outputs stop playing audio and play high level electronic noise; iConfig works normally except for audio meters, which don't display anything even if audio softwares keep running as if nothing happened.

Everything else is working properly: ICA4+ front panel controls, iConfig and iConfig controls, all softwares keep running (I didn't have a chance to check midi during these events).

The problem was present while firmware on 2.0.3.
Issue was happening only seldom and in the last year I've been using ICA4+ only at home, so it wasn't bothering me enough to investigate further: I power-cycled the soundcard and went on working.
In the last weeks the problem started becoming more frequent. Hardware or software configuration hasn't changed or moved (I do my live-sound work with AUDIO2+), so I tried connecting the audio interface straight to computer (before was through an USB 3.0 hub).
Still getting the noise every once in a while and needing to reboot the AUDIO4+, yesterday morning I tried updating to 2.0.5 and the issue is showing more frequently.
I cannot track the problem to a specific software nor duplicate the behaviour on purpose.

Unpatching everything from analog outputs on iConfig doesn't stop the noise, which is present on all outputs, and its level responds to volume and mute controls for every channel.

Power-cycling the unit restores the normal working condition.

Only iTunes running. It happens again, and again.
Tried also resetting card to factory settings, but issue manifests anyway.

Tried changing audio frequency and bitrate, USB cable, USB port, computer...

Any idea?

Thanks, regards
G

  • I’ve got exactly the same problem. No solution yet?
  • gis took the right steps in his approach to troubleshooting.
    Reload firmware
    Factory Reset
    Try a new USB cable, try another USB port on computer.

    The sound would likely be made but a crashed processor in this case. 
    This could happen with some bad data which a bad cable could cause.
    This could happen because of bad information from a firmware load/setting mix up, which is why the factory reset and firmware load is good.
    It could happen in a very hot place, without good ventilation.

    These would be my first options to test out.
  • Tried all suggestions but it didn’t change anything.
    The problem is intermittent. Yet to determine the cause but noticed it happens often if using the YouTube app on iOS.
  • I’ve got exactly the same problem. No solution yet?
    iConnectivity offered out of warranty repair.
    I've not yet considered the option because I've been working very little since covid lockdown in March.
  • I've just had this happen a few times this morning with my ic4+  - so far only with audio streaming form the internet (youtube, radio, and other sources).

    I'm just now letting ableton loop out and it's not happened yet after ten minutes or so... very weird

    For me it has disappeared for a long time, and it's happening again since a few weeks.
    I'll keep track of devices connected and iCA4+ settings when the problem arise.

    Maybe we can track some information in this topic, when the issue does happen.
    What can be useful to know? I try drafting a list.

    iConnectivity AUDIO4+ USB port 1

    • USB cable plugged in? Yes / No
    • If cable plugged in, what cable are you using? (USB-Lightning, USB-Apple 30-pin, USB 2.0, USB 3.0, USB 3.1, ...)
    • Computer or device connected? Yes / No
    • If connected, what computer/device are you using and which OS version is running?
    • If connected, what computer/device are you using and which OS version is running?
    • If connected, are you connected directly to computer/device or are you using USB switches or similar? Direct/Switched
    • If a computer is used, which version is the USB port you connect to?
    • Which softwares were running audio on USB iCA4+ port 1 when the problem showed up?
    • Which softwares were running midi on USB iCA4+ port 1 when the problem showed up?
    • Which iConnectivity softwares are on this computer/device and what are their version?

    iConnectivity AUDIO4+ USB port 2

    • USB cable plugged in? Yes / No
    • If cable plugged in, what cable are you using? (USB-Lightning, USB-Apple 30-pin, USB 2.0, USB 3.0, USB 3.1, ...)

    • If a computer is used, which version is the USB port you connect to?
    • Which softwares were running audio on USB iCA4+ port 2 when the problem showed up?
    • Which softwares were running midi on USB iCA4+ port 2 when the problem showed up?
    • Which iConnectivity softwares are on this computer/device and what are their version?

    iConnectivity AUDIO4+ USB host port

    • USB cable plugged in? Yes / No
    • If cable plugged in, what cable are you using?
    • Is a device connected? Yes / No
    • If connected, what device are you using on the USB host port?
    • If a device is connected, does it have its own power adapter or is it powered through USB host port?

    iConnectivity AUDIO4+ settings

    • Hardware Version
    • Firmware Version
    • Number of buffered audio frames
    • Sync factor value
    • Audio configuration
    • Clock source
    • Mixer configuration
  • Good call, I think (hope) that I fixed mine by doing the firmware update - I had it once more lately when I was streamng again but it didn't repeat...
