I have the same problem. Wether in bluetooth mode or in PC mode, it goes to sleep. Super annoying.

I think this may work.

This doesn’t work, they still sleep after 10mins or so.

I have tried everything. No change.

Who would even want this feature?

I will probably return them if I can’t get a fix for this.

I had this this morning after installing them yesterday.  Wired usb connection.  I’ve updted firmware to latest release & in the speaker power option in synapse 4, the power saving option is disabled.   Yet this morning, no usb audio on the PC.  

Did you get a fix for this?

I too will most  likely return if not sorted - I had the chroma nommo before, but had to replace those with these after the usb audio failed and then the line in / output started failing….

Ive had mine for months now. The random powering off went away but since Synapse 4 its come back. Ive installed synapse again, turned off the power saving and deleted and reconnected the Nommo V2 several times.

Ive gotta say i like Razer products but their drivers for these speakers are horrible and so is this support site for quick support.

I'm having same issue with Nommo v2. Does anybody found a solution?

If not, I will return them. It's frustrating to spend the day turning on the speakers

Ive got a ticket in with support thats about two weeks in for all the sync issues with Synapse 4 and about every razer peripheral I own. IF i get a resolution ill post it here.

Same thing happend, I tried to turned off power saving mode, doesn’t work. And also change the PC power setings of USB to disable the auto power off, doesn’t work.

I've opened a ticket too and the conclusion is that the speakers are poorly designed.

I've returned and I will buy Logitech speakers.

I had the same problem with the Nommo V2 speakers using Synapse 4. Only way I was able to fix was to go back to Synapse 3. So far have not had any issues with speakers turning off automatically after disabling power saving in Synapse 3.

Unfortunately it seems the Axon wallpapers require the Chroma app installed and it has to have Synapse 4, so now I’ve lost the ability for Axon to sync my RGB with wallpapers.

I had the same problem with the Nommo V2 speakers using Synapse 4 . someone have a solution about this issue ? 

Every time I turn them on manually, do you have a solution to turn them on via the computer?
