Bug Report Dropouts in the audio


New Member

I use Zedi8 mixer for recording old sound cards, I have dropouts in the sound:
@ 0m28s: https://youtu.be/KnSSASTcTfA?t=17
@ 3m07s: https://youtu.be/s3omKoN5sak?t=177
@ 0m28s: https://youtu.be/E3Sch10h_mI?t=20
@ 0m21s: https://youtu.be/eSCaDhASfyI?t=16

It is strange why around mostly 30-60s (I cut these videos). I did not hear any glitch at the recording in the sound, but if I play back many times accidentally there. It is total random, where, and when (the most of the videos are OK). I use OBS for recording.

Here is another type of issue - strange echo effect around 50s: https://youtu.be/tY1qzuRtf8o?t=44

I also had previously two interesting issue (I deleted these videos):
* in the middle of the video an audible frequency change (similar like a cut in the frequency over 5kHz)
* distortion, echo like "effect" at the recording - the input/output sound levels were OK

A part of the video is OK, and there is a switching - I have no clue where is from. I use the latest drivers and updates, I don't use the computer at the recording, and the CPU workload below 1%.

I find it really sad that this issue has not been addressed yet. I use the ZEDi-8 as well, and am experiencing the EXACT same issues you are. I don't think the problem is solely on the ZEDi-8 because when I use software like Adobe Audition, whether run through ASIO or WASAPI, I don't get these issues. It only ever happens with OBS. Could be that OBS and the ZEDi-8 just don't get along...
