A small Marshall Amps Guitar Combo Amplifier (M-MG10G-U)
Guitar cords
iPhone 16
JBL Tune 720BT headphones that came with a hard wire cable that goes to the amp headphones jack
Another cable that goes from the iPhone 16 to my headphones (USB-C to 2.5mm TRS) that I bought
When I try to use the Justin Guitar, the app cannot hear what’s coming through my amp (I can). I checked and the app has permission to my microphone in the iPhone settings. If I unplug my headphones, the app hears my amp and I can continue through the lesson but the whole thing is quite a pain and I figure there’s got to be a better way.
These apps want you to use wired headphones. OK. But it’s simply not hearing anything when I do.
Any advice from someone who has been through this? Another cable? Ditch the headphones altogether? TIA
I did get a less than useful response from Musictopia that didn’t relate to my issue. This happens with all sound recognition in the Justin guitar app not just OMCs.
I used to work in tech. Support do Apple so I have a reasonable idea of what maybe causing the issue.
Musopia may have implemented the software requiring dedicated use of the Mic. iOS will not like this as is prioritises mic for possible phone calls
When you plug in an adapter to connect your headphones the iOS detects this and sets it for a wired mic input the headphones, as you do not have headphones with mic JG app does not detect sound
Musopia is coded to get sound from the built in Mic or the Mic wired signal if detected, the cable from headphones to iPhone may not be detected as an external Mic input or there is no signal from headphones down that cable to iPhone
I suspect 3 is the most likely cause is that when connecting the input to your iPhone iOS sees this treats it as having a mic input but there is not one.
Headphones go to into this to monitor guitar and sound guitar input goes to iPhone app via usb interface as if Mic.
This works for me with RIFF both on iPad and iPhone.
BUT it really depends on how Musopia have coded the JG app as well. I use my set up with the Gibson app which detects external hard wired devices and switches between mic and device accordingly.
Thanks. I was hoping that an alternate cable or setup would suffice. Or perhaps an Apple setting to ignore headphone mics.
Buying another piece of hardware puts me out of my price range (considering the app cost). I may have to stick with the website for another three or four months.
I think this is the likely cause. my wife used her ipad for music stuff and for certain apps, she has to use the apple usb-c earbuds with built-in mic to be able to record and monitor audio from the tablet through the headphones
Every time iPhone goes through another update, something that used to work gets broken. They just do not know when to stop. Historically, I could listen to music and radio on the iPhone at the same time I open other websites. Since the latest update, the iPhone can only handle one job at a time – it shuts off my audio when I open any other app or website. I have followed all the instructions to fix this, to no avail. Common complaint. My first guess would be to blame Apple.
Sounds reasonable yet - how many other people are out there that don’t use Apple headphones, got to be a ton. Tech support said they had information but their link was bad.
Checking with some of the other apps before I plunk down a lot of money.
I think others work as long as there is a microphone attached to the headphones somewhere. The apple ones are a known entity, though, and app developers probably test with those and not the huge variety of other brands. therefore they cannot guarantee other brands will work.
