breabill Posted April 7, 2022 Report Share Posted April 7, 2022 Hi All, I just want to give a heads up to folks regarding issues I've encountered with the MixPre-10ii since upgrading to FW 7.16. On two of my last 3 jobs I have encountered a single occurrence each of a recorded file being discontinuous in the middle with upwards of 9 video frames worth of data missing in the recording. This of course resulted in loss of lip sync with picture - I had to find the point at which the "skip" occurred in the timeline, cut the audio file at that point, and then move the remaining audio 9 frames to the right in order to reestablish proper sync. Unfortunately, this left a 9 frame audio hole in my project but I was able to use the "mix out" from the recorder captured on camera (scratch track) to cover the missing audio without it being too obvious. I've subsequently downgraded to FW 7.14 and have run 3 one hour plus takes and have not been able to duplicate the problem. SD is aware of this issue and at this point has no information regarding a root cause assessment. FWIW, here are the details of my setup: 6 line level inputs from venue soundboard, plus 2 mic level inputs from my stereo audience mic (ambience). MixPre L/R mix output via xlr to my camera as a "scratch track" for reference. 64GB SanDisk Extreme SD Card 128GB Samsung USB thumb drive (for backup) Timecode Input via BNC from a UltraSync One MixPre "Sync Ref" is set to BNC In 32bit float, 48khz, 23.976 frame rate Quote Link to comment Share on other sites More sharing options...

Michael Render Posted April 8, 2022 Report Share Posted April 8, 2022 Thanks for the heads up. I was just about to update to 7.16. I guess I will hold off. Quote Link to comment Share on other sites More sharing options...
Barry M Posted April 21, 2022 Report Share Posted April 21, 2022 7.17 just released, seems to address this. "Rare, brief interruptions of audio in recorded files and USB outputs no longer occur." https://www.sounddevices.com/download/?prod=mixpre-10-ii Quote Link to comment Share on other sites More sharing options...
Michael Scrip Posted April 23, 2022 Report Share Posted April 23, 2022 It just occurred to me that I might have experienced this bug back in March on my MixPre 6 II running the 7.16 firmware. I shot a 90 minute dance show and somewhere in the middle the sound got out of sync. I didn't think anything of it until now. Hopefully 7.17 fixes it. Next month starts dance recital season! 😎 Quote Link to comment Share on other sites More sharing options...

It happened on my MixPre-3 too (which also received the fixed firmware now). I don’t think the bug was as rare as the firmware notes suggest.
