USB points with macbook professional and audio interface

Hello I’ve this very odd subject with a late 2013 retina 15″ MBP (ME294LL/A) 16gb 2.3ghz i7

I’ve an apogee symphony desktop audio interface related through USB.

It was working tremendous for like 6 months once I obtained the apogee (I purchased the laptop computer used) after which all of the sudden whereas recording in Logic Professional X the audio interface simply stops transmitting audio. It would not disconnect from the pc although, it nonetheless reveals at related, however there isn’t any audio. There’s additionally no audio if I attempt to hearken to anything (youtube, spotify and many others.)

After I change to laptop computer audio system on the spot, the audio performs. Then I change again to apogee and it would not work. Just some combo of restarting the interface unit itself and/or the pc makes it work once more. But it surely solely works for a couple of minutes earlier than disconnecting.

The identical subject occurs if I do not even use Logic and simply hearken to youtube or one thing. Once more, the gadget itself (and it is management software program) don’t disconnect, simply no audio.

I’ve contacted the producer and we spent per week attempting various things. They thought it was the unit in order that they despatched me a brand new unit. The identical subject occurs with the brand new unit.

I’ve tried resetting nvram, smc and many others., we have gone via all of the steps with apogee tech so far as reinstalling the software program. I’ve even tried doing a contemporary set up of OSX with no knowledge being saved.

The one different usb gadget to check is an android cellphone and it connects tremendous and transfers knowledge. No different USB gadgets can be found to check.

I did an apple {hardware} check and it handed.

The issue occurs in each usb ports.

Does anybody have any recommendation. Can this be as a result of a nasty usb controller chip? It appears not like to be on the port, because the gadget connects, and identical subject with each ports occurs.

I am pondering possibly it wants a brand new logic board? Or can I take it to microcenter or one thing and have them exchange simply the usb controller chip?

It is so perpelxing what the issue may very well be! Any recommendation/perception can be useful thanks
