Lofi signal on USB streaming from computer to QU16

[Seb]

Hello,

I wanna use my QU16 as a sound card but the USB streaming from my Mac book pro (dual core 2ghz, 8goRAM, hybrid SSD HD 500GO + Yosemite) sounds really bad (kind of lofi/distortion/flanger), from the DAW/Ableton live or Itunes whatever the ch1-2 or ST1/2/3 i choose.
I checked the forum but did not find another similar topic, anybody knows what’s the reason?
The QU 16 firmware is V1.62.
Please A&H team help me to solve this issue.

RGDS.

what are your core audio settings?

Hello,

Config:
Mac book pro 13″ (mid-2009) => 2,26 GHz Intel Core 2 Duo.
Ram => 8 Go 1067 MHz DDR3.
OSX => Yosemite 10.10.4.
HD => hybrid SSD 500GO.

Core audio settings:
-into utilities: I/O audio midi => In: 24 Out: 22 QU16 internal Clock => 48KHZ 22ch-24bits. (no option of buffer size to select).
-into my DAW => Ableton live 9.2 => Buffer size: 512smp, in: 12.9ms out: 12.7ms.
Remark: whatever the buffer size (128/256/512) the result is the same = lofi/distorded/noisy sound.
I start to think that my QU16 unit is out of order (regarding USB/audio streaming) or do you have anything else to suggest to check on my computer?

Regards.
