When I'm listening trough my native PC audio card (3.5 mm jack), the max volume is much higher and I don't hear any noise.

My recently bought audio-interface M-Track II is worse at this when listening through headphones (I connect trough a 6.3mm TRS adapter). Firstly, the max gain is lower. Also, the idle noise is present, but only at higher gain

Can You explain me why is that and how this can be fixed?

    Have you tried turning the Monitor knob all the way up before gradually turning up the headphone output from 0 to desired level? Commented Jul 27, 2016 at 11:31
  • And does it happen only with headphones (i.e. not with the main output connected to powered speakers)? And does it happen regardless of the gain level of the inputs? If the gain is too high (e.g. maximum) you may be hearing the noise from the preamps, not from the headphone output itself... Commented Jul 27, 2016 at 23:48
  • What do you mean by "idle noise"? Is it a hissing, like white noise?

  • @SimonBosley What is that monitor knob? Commented Jul 29, 2016 at 12:35
  • @DarekBuryński Rightmost large dial on the front of the audio interface, should be labelled. Commented Jul 29, 2016 at 13:48

Turning the monitor control all the way should give you only the playback source in the output.

The monitor control is there to set the amount of direct input to playback when you're tracking live musicians.

In your case you just want to hear the playback at 100%, without any noise introduced at the inputs.

Hope this helps!
