Crosstalk from cable box on Altair headphone jack

I am getting some noise from my cable box when I listen to headphones on my Altair G1.
Any suggestions how to rid myself of this nuisance. I have a Furman 15A noise and power conditioner, running the coax cables through the Furman. Seems either the jack or the headphone cables are acting as antenas and picking up a faint signal from the Xfinity Cable Box. I moved the Altair up one position with my Oppo 4K DVD player in between but no change.
Suggestions?

what kind of signal?

It is the audio from the cable box, faint but there and distorted, people’s voices which if I turn on TV I can see they are synced with what is going on screen

If you turn the volume of your TV all the way down to zero, will you still hear the audio from your headphone?

Volume of the TV has no effect on the issue, not coming from the TV. TV on or off same interference/noise in the headphones. It seems to be picking up RF from the cable box. If I turn the cable box off then it goes away but I want my cable box on all the time for recording programs. I have tried other headphones to see if the headphone cable was acting as an antenna but no matter what I plug into the headphone jack on the Altair it seems to be getting this interference indicating it is something the the Altair acting as an antenna, the jack or some internal component in the headphone circuitry. I do not get this noise when running the Altair through my amp and loudspeakers.
I may have to rearrange my equipment in my media cabinet to move the Altair as far away as possible from the cable box but not sure that will completely fix the issue and or come up with some sort of shielding. Thanks for you responses, let me know what you think might resolve this.

Talked to another engineer and I have been thinking about this problem for a while. What I want to do is to see if the interfering coming from air (RF) or from any wire. My guess is if the signal is coming from air, then the noise should get lower when you move the ALTAIR awal from the cable box, or you can simply move them closer and see if the noise is getting louder. If the noise is coming through any wire, that movement will not affect noise level.

Let me know what you can find out and we can go through next step to fix it.
