J Tech Digital HDMI Audio Extractor

This worked great up until the 8 month mark, after which it stopped outputting video while audio still worked. I went through all the usual troubleshooting tips, tried it with my chromecast ultra, samsung blu-ray player, 2 different laptops, and gaming desktop with a 3070. All of them played audio through this audio extractor but the TV still said no signal. Bypassing the extractor and plugging each of these in directly worked fine. At first, support was helpful and they sent me a replacement, but the replacement had the same issue. Wanting to determine once and for all if it was the extractor's fault, I bought another brand (the VPFET HDMI audio extractor), and lo and behold it worked perfectly using the exact same input devices and cables I was using with this one - essentially proving that something in this audio extractor had stopped working with my setup. Here's where support started to get annoying and useless, after I sent it back again with an excruciating amount of detail about the video modes of every device I tested it with and with the information that a different audio extractor worked fine, proving that theirs is faulty, I was given back a video of them using the device with their own TV of a different brand as if that proves that it doesn't have issues with any other device (and they didn't even use the same generation chromecast that I used it with, not that it matters as much since I tried 5 different devices to no avail). At this point they are refusing to do anything other than return to me the malfunctioning unit or give me store credit to buy another one of their products, which obviously is useless to me since I already needed to buy another brand to prove that their audio extractor was the issue, and if they returned the unit to me the only thing I can do is toss it in the trash since the HDMI output is broken as far as I can tell. 0/10 do not buy, the supposed 1 year warranty just gets you a broken unit sent back to you. Get the VPFET brand one instead as it seems to have higher compatibility and isn't plagued with the issue I have with this one.
