phoo Posted June 25, 2020 Share Posted June 25, 2020 My older studio setup has developed interference when a second monitor is attached to the laptop to mirror the screen. I've done this in the past but don't remember problems. Current setup is a G10, GuitarPort or UX2, and and older HP laptop. It's used as a standalone amp sim setup for recording, though it is connected to the internet wi-fi (disabled sometimes that that does cause interference at times, G10 dropout). All are normally plugged together into the same laptop for power via USB. The extra monitor is an older monitor previously used in the main desktop. It has been used in the studio setup for a long time with no issues such as this. There are rhythmic bursts of noise, audible even when the volume of the GuitarPort or UX2 is at a minimum. The timing seems to be around one burst per second, a half second of noise. The bursts are visible in the meters in GearBox, even when the GuitarPort physical volume is at a minimum. This happens ONLY when a second monitor is plugged in to mirror the screen. It happens whether HDMI or SVGA is used (the only two ext monitor options on the laptop). The interference does not seem to be proximity related. I've moved everything away with longer USB cables and have tried using different USB ports so the video connections and audio USB are on different sides of the laptop. No dice. Unplugging the G10s audio out, GuitarPort input, taking our the guitar cable between the two, does indeed stop the noise, but that mean there's no input audio at all to the GuitarPort from the G10. This also stops the visible meter action in GearBox. This seems to imply that the interference is coming in through the audio cable, even if the audio cable can still be plugged into the GuitarPort, oepne ended, if not connected to G10 out. I'm still feeling like this may be THE issue, but so far it happens with all cables, and even when the monitor itself is many feet removed, like 6 feet apart. There is no level change that distance might help with. Plugging the G10 into any other charger, across the room for example and running a longer audio cable changes nothing. (distance and removing the USB connection of the G10) This is new, and is directly related to the change to add a mirroring monitor. No extra monitor, no problem. I'd like to understand the issue better before looking into other solutions, such as replacing the laptop or extra monitor. Doing those things may not actually alleviate the problem if this is a known unavoidable problem with Line 6 devices. THANKS! Quote Link to comment Share on other sites More sharing options...
