I had a problem with the playback audio. I listen during the playback a little random flanger on Left/Right channel. It's always random on time (sometimes really short, like a flanger, sometimes longer like a delay.
Sometimes i can see on my Motu 828 mk2 (Fireware) the difference on the meter on the audio interface.
It's always random, sometimes happen sometimes doesn't.
I play Video (in MPeg4, h264) and audio (AIFF 48Khz, WAV 48 Khz, doesn't metter the extension, that problem happen in both of audio).
My set up is:
Motu 828 mk2 Fireware on production.
