I'm assuming you tried another coax cable?

I did test the board outside the case, micro USB still doesn't work. Don't have a multimeter. In any case, I got the correct coaxial cable, and that port works perfectly. So now I'm using optical port for the PS4, and coaxial for the MBP. I'm sorted. Better than spending $200-$300 in order to...

Oh, just a regular mono 3.5mm pin will work? I saw those on Amazon, I thought they wouldn't work lol. Thanks!

I already ruled out 1-3 earlier, and I tried cleaning the socket as well, as much as I could. Unfortunately I got the wrong RCA coaxial to 3.5mm cable, but for now MBP USB to Signstek USB to Signstek Optical to Mojo works, so I have sound from the MBP through this way. I don't know which is the...

Yeah I totally understand your feeling. What sucks for me is that I don't even unplug from the microUSB often, only when I'm using the PS4, which is a few times a week. Oh well. At least I managed to solve my problem in an inexpensive manner. I hope the optical and coaxial ports last long.

The new USB-C MBPs don't have it built into the 3.5mm jack anymore. :( Otherwise that would've been the perfect solution. Yup, I got the same pricing/quote, and I'm pretty sure it'll cost me $300 as well. I just got the Mojo a month back, for $410 from Head-Fi sales forum, so I don't really...

I opened it up, and took as many photos as I could. https://photos.app.goo.gl/EETfuX2hdqx1EDTy1 I can't see anything wrong with it, physically. There doesn't seem to be any dust or particles. The weird thing is, Mojo is detecting a cable being inserted, as the optical input from the PS4 gets...

That's really good of them, but it's annoying that a failure is the microUSB port not working, and having to pay $300 to replace the whole board because of that, when the DAC/Amp etc is working fine with other inputs. I haven't been able to open the Mojo yet, this weekend for sure, was swamped...

Ah, I understand you now. So the Mojo actually detects the USB cord being plugged in, since the sound from the optical input gets cut off as soon as I plug the cable in the data port. Makes the problem even more weird.. it’s able to detect a cable being plugged in, but the MBP doesn’t detect...

Ah okay. I saw some posts earlier as well, (skimming through this thread). Anyway it’s the nature of electronics, failures are going to happen. I haven’t done anything to try and fix it, been busy with other things. I don’t have the tool needed to open this up and take a look, but tonight I...

I realise I worded that badly, I meant it's not a one time ultra rare problem that just happened to me, it seems be a rare recurring problem happening to a couple of people. Considering the Mojo is just two years old in the market, I have a feeling more people will have this problem in the...

Damn. It seems to be a common problem, which is troubling.

I assume opening the Mojo up and seeing if I can fix it myself isn’t advisable? (Warranty has expired)

Another weird thing I noticed, the sound from the PS4 via optical input actually gets cut off when I plug the microUSB cable in. Even though the input does not work, the Macbook does not recognise the Mojo, the Mojo knows that the microUSB input port is being used. (Mojo doesn't have an input...

I haven't tried USB input with other devices, mainly cause I don't have any other device other than my MBP to use with the Mojo. Like I mentioned initially, the USB input port seems to be the problem, since optical input works just fine with the PS4, charging works fine with the same micro USB...
