Topic: UFX clicks in idle state

Hi!

I have this strange problem that on the first 8 analog channels, there is some click noise (2-3 in a minute). I don't know what cause this, as this is happening in idle mode, when no software is running.

System: mac osx 10.7.2
totalmix: 0.962
ufx firmware: v351
driver: v.1.63

Re: UFX clicks in idle state

Nothing connected, no word, no AES, no ADAT, and the unit is in internal clock mode? What sample rate? Also doing this in stand-alone mode? You can check this via a monitoring to the phones.

Yes, nothing connected, internal clock, both at 48 and 96kHz. Will check it later if it does this in stand-alone mode or not.

Re: UFX clicks in idle state

It seems that it is the same in stand-alone mode. No cable connected, internal clock, and only the first eight analog inputs does this, nothing else. I did the same with snow-leopard, now I'm on Lion, and it's the same. I've tried different machines also, symptoms are the same. Is this some firmware thingy?
These weird things sometimes are as low as -80-100dB, but sometimes as high as -30dB. When I switch on at the morning, it seems worse, but that might be only my perception.
