Hi all,

I am using my Flex Balanced for over a week now and really like it. I was able to do measurements and get the speakers x-overs done etc. I used REW and played the sweep through the USB audio input on the Flex. Nice and easy.

For the life of me, i can't get REW to work anymore this way. I tried about everything (i think) but i cannot get any sound from my Mac played through USB to the Flex. Not through REW, not even 'normal' audio using Spotify, VLC Player etc etc. I can access the Flex through USB and all other inputs (optical,spdif) work fine.  The Flex shows up in the Midi Setup and in other applications as well.

Any hints? I hope it's something I am missing.

Thanks,

Stefan

Edit: I'll try a different Mac tomorrow to exclude that from the equation.

I disconnected the power last night and tried again this morning. Works fine now. Go figure.

Hi Stefan,
I have the flex digital version that I tested first on my office computer (PC windows 10) It works via USB input for a couple of days and then sudently, no sound anymore through USB input. The only way I've found so far was, as you did, to disconnect and reconnect the power supply of the Flex to get the sound back ! So it is not related specifically to mac but windows OS too.
A reboot of the computer and or an unplug of the USB cable did not change anything. The only solution to recover the sound was to disconnect Flex power and reconnect it.
It is very bothering...
Then, last week I moved the flex to another computer and since then, it works ok there. SO what can we deduct ?
- it is a bug related to flex hardware
- it will be hard to track it down as it seems to be hardware dependant
Looking forward to minidsp team suggestion...

Hi All,

Same problem here, except there's never sound using the USB input. Laptop detects the Flex no issue. (Un)power the Flex didn't help.
Otherwise everything works fine, but missing the point somewhat when USB audio isn't possible.

Update 24-07-22: After contacting MiniDSP support, they continuously adviced the source selection was set wrong (not set to USB). However, it was always set to USB, but no sound. My solution was to unplug the Flex from power, attach the USB cable to Flex and laptop, then switch on the laptop and then power the Flex, and it worked. There was never a problem with the Flex PEQ interface, only when trying to play music or soundfiles from the laptop or REW.

I have issues with my miniDSP Flex Balanced USB audio as well. Occasionally, the unit won't play sound via USB. I used two sources so far: windows 10 PC and an iPhone. At first I thought it might be a cable issue, but then I tried two more cables, including the one which was shipped with the unit.
Turning off the unit, detaching the power cable and waiting for more than few dozens of seconds and then turning the unit on helps to get the USB audio work again. I don't know exactly what causes the issue, but I think that it has to do with the fact that I am switching between different USB audio sources.

Having to power of the unit after attaching another USB source is a bit annoying. Moreover, I hope the USB audio won't eventually stop working.
