Glitchy sounds on 7.1 surround

The last couple of day’s I’ve noticed weird noises comming from my surround back speakers when playing stereo tracks. Some of these noises are from the the track and some sound very glitchy. Normal all stereo track only play on the front speakers. This is only with Audirvana. I have no problems with other players like VLC or Itunes.

Hello @LaZyLiFe,

Can you send me a copy of the “Debug Info” while connected to your DAC? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info Audirvana button automatically copies all its content, all you have to do is paste it in response to this message

@Damien3 only removed my name for privacy reasons.

Since you have upsampling activated, can you change this settings to “Power fo 2” or deactivate it?

@damien3 I cannot change anything in audio settings.

To change your audio settings you’ll need to stop your audio (the square icon)

@damien3 Yes changed to deactivate.

@damien3 Seems to be fixed. thanks!
