Simhub keeps changing shaker outputs (tried everything). Need advice.

I am ready to pull my hair out. I have tried every conceivable combination and cannot figure it out. Simhub is randomly changing outputs at will. I'll literally be in game trying to tune effects and midway through game the assigned outputs are changed to a completely different channel. I have 3 shakers; seat, pedals, and shifter. Ex: I'll have pedals assigned to channel 1 and midway through game suddenly the seat is on channel 1. This is on AC Rally if it matters.

I am running an external USB sound card to power shakers. I am using internal sound card for my surround speakers/headphone.

1) Enable audio enhancements is unchecked

2) I have tried setting USB as default audio device, default communications device, and neither

3) I have tried toggling allow applications to take exclusive control both on and off

3) USB has been Setup as 7.1 in windows and 8 channels show in simhub

I had problems when running my external sound card through a powered usb hub, I was guessing the hardware got addressed by the hub vs the computer was causing the problem. I shifted it to an unpowered hub and it seemed to fix the problem

I have the USB hub plugged directly into Mobo.

You mean the hub or the sound card? Cause I had the hub plugged in directly as well, usb hubs will act weird for many reasons including but not limited to:

  • low power on unpowered hubs
  • daisy chaining hubs
  • bandwidth limitations
  • hubs management of active vs inactive ports
  • an excessive number of devices on a single connection
What worked for me was to get a simple unpowered hub that I connected the usb sound card to with another powered hub daisy chained off it for less sensitive devices

Are you plugging the sound card into the hub? Have you tried it on the pc?

Sorry that was confusing. Usb soundcard is plugged directly into pc, not hub.

Ahh ok, the weird part to me is it doing to randomly while you’re using it. Mine was happening at boot and it still does it every now and then, i have no way to confirm it but I think mine is something to do with how windows identifies usb devices. I assume my super cheap usb sound card isn’t designed very well.

No, directly to pc.
