Topic: White noise issue only with line output 4
Hey all,
Brand new to the forum, been using RME products for almost 10 years. Wondering if anyone has any advice for me on this: today I tried using line output 4 on my Fireface 400, and when I first plug it into a speaker it is dead silent like all the other outputs, but when I play any type of audio, a loud white noise hiss plays through the speaker connected to line output 4 only. If I turn that same speaker off and back on, the noise goes away completely until I pass any audio through it again, and then the white noise comes back. Even after I stop playing audio and mute channel 4 in Totalmix, the white noise continues. It only goes away when I turn the speaker off. It does play audio, there's just alot of white noise mixed in only when using output channel 4.
I've tested all other line outputs with the same speaker and all of them work fine. No other known defects with the unit. Is channel 4 on my unit just defective?

Any tips very much appreciated. Thanks!
