Topic: UFX+ WDM make pop noise when changing sample rate

After I change the sample rate on config page, the channel not belong the current WDM devices will make pop noise continuously.
I set one WDM devices with multichannel and the problem look like below screenshot.

And by the way another question, could extend the Q value of UFX+ eq to [0.7,9.9]? It seems that some channel of the ADI-2 could do that, I don't know wether it depend on hardware or firmware, I post this question on total-mix section (https://forum.rme-audio.de/viewtopic.php?id=32824) but no response.

It seems that the problem was on the WDM driver:
Noise will disappear after no output to WDM driver (all channel/device) a while.
If make test signal to one WDM device, the pop noise will disappear on that device's channel.

Re: UFX+ WDM make pop noise when changing sample rate

You have to open the Sound control panel and watch what is happening: the WDM devices are all removed and then generated newly. Obviously a running WDM software will not know what is going on and fail to send correct data until it is reset. In other words: do not change sample rate while WDM is in use.

OK then, I will stay sample rate when using WDM driver.
What about another question? Is Q limit by hardware?

More by usability and compatibility. We have no plans to change the EQ in TM FX.

Thanks for your explanation. At least it's possible to add more Q range wink.
