Very strange v1.5.1 behavior

Just upgraded to v1.5.1 and having some very bizarre behavior.

Pulled up a 96k multitrack recorded on this SQ-5, off my T5 500GB SSD, all is fine, until a few minutes…

Audio starts sounding like it’s stuttering, faders 1, 7, and 8 take on a mind of their own and start jumping up and down.

Audio goes back to normal, then resumes stuttering, this continues on even if the virtual sound check is stopped, faders still bounce around.

Restarted console 3 times, each time this behavior resumes.

Is you’re SQ connected to any network?

Hi Ian,

That is indeed strange behaviour and I’ve never heard of anything like it before.

If you haven’t already, please contact us using support.allen-heath.com, if possible with a video and/or copy of the recording (I appreciate this could be large and a pain) along with all other details of the setup, so we can try to reproduce this and discover what’s going on.

Thanks,
Keith.

Hi,

Did you checked the 1.5.1 really installed into your mixer?
Check the firmware version on the Utilities/General/Diagnostic page!
My colleague installed it four times by the time he succeeded.

Here’s a small clip of what I’m experiencing.

Ian,

this looks like strange earth effects and gravitation issues

OK seriously… there is something wrong with the hardware
you should send it to the sales rep or distributor

I feel like it’s software. Everything was fine (except the screen freezing) before I upgraded to v1.5.1

v1.5.1 caused this to happen literally 5 minutes after the update, and continues to sporadically happen. Sometimes within minutes, sometimes 20, but it always happens at some point.

Have you reinstalled the firmware?

I’ll try re-installing the firmware at some point today.

I’ll also do a backup then full factory reset to wipe out all settings, maybe there’s something tiny setting they missed moving to 1.5.1?

Just an update as I’ve finally got around to this.

I did a factory reset (holding EQ and HF in during boot) and the problems still persisted.

Did a firmware update again (1.5.1 over 1.5.1) and it seems to have worked knocking on wood, literally

I’ll leave it on doing nothing for a few hours and make sure the ghosts have left.

If I don’t post back, assume this was the fix for anyone in the future with this strange issue.

Unfortunately the issue has reared its ugly head again.

Even after a full reinstall and factory wipe, the problems still persist.

99% sure this isn’t a hardware issue since console was totally fine until the day I installed v1.5.1

We have had a problem very similar to this occur 3 times now during church services. The stuttering, and then faders move on their own, often to max, with frightening loud volumes. It’s a SQ6, with an upgrade to v1.6.1 about a month or two ago. Is there no resolution to this problem?
The last two times, there have been no tablets with Mixing Station in use.

I repeat my above statement, consult your dealer or distributor.

We had a lot of advice and tried many different treatments to fix this issue, but had no success. I finally decided to open up the mixer and check the connectors, especially ribbon type. After this, the mixer started to be behave, except for channel 19. After reseating the connector to that channel, all was good. It’s been almost a month now without any issue. Now we know.

By the way, there were also a few dead ladybugs in there, I doubt that was the cause, but it let us joke that the mixer was buggy.
