I have a 'man cave' set up in my house and have run into a rather worrying problem, every time an electrical appliance is given electricity (either through plugging in or turning on) the audio on my speakers cuts out. But first let me explain the setup.
Gaming PC (650w PSU), Xbox One and Sky box all connect via hdmi to an Optoma Hd141x projector. The connection is currently being supplied manually via a two sided female hdmi dongle. (Although HDMI switches have been used but more on that later)
The audio system used is a Logitech z906 which is connected directly to the projector with a 3.5mm audio jack and audio is supplied via Hdmi.
Attached to the underside of my desk are 2, 6 port extension plugs all surge protected up to 13,500 A. One of these extension cables is connected to a regular 3 port extension plug which then plugs into the wall socket via a surge protected adapter (also 13,500 A). The other 6 port plug is plugged into a regular 3 port extension which then plugs into the wall again through an adapter. All devices mentioned above including monitors and the projector are spread over the 2, 6 port extension cables. On one 3 port connector a lamp and a Husky mini-fridge is plugged in and on the other a digital clock and the sound system.
Sorry if that part is a little confusing.. Essentially all substantial suppliers of electricity are on surge protectors whilst low electrical use appliances are not.
So back to the problem when an appliance is turned on the audio cuts out for some reason, this especially a problem as it occurs every time the mini-fridge re-initiates cooling. At this point I reckon that it is a HDMI surge which is going through the projector and is not strong enough to knock out the projector video feed but is the audio. I came to this conclusion as when using a HDMI switch with an audio extractor all was fine. But, this then led to a problem... I am now down to my 4th HDMI switch, all previous 3 have been fried in some way or another at various points depending on quality. So, that leads me to the second problem... I am actually scared at this point to plug in my new switch incase it too follows the pattern of becoming fried. Therefor my second question is why is this happening?? Is it due to a HDMI surge overloading the PSU on my switch or something else. I have invested in a single HDMI surge protector yet I am not sure on which cable to put this, one of the inputs or the output? If you have any ideas please feel free to help.
Cheers,
Mark
