Hi,We recently upgraded to v0.5.5.3 and now we have a periodic popping noise and overall lower quality audio. Same laptop, configuration, etc. The audio quality is poor enough that we cannot do recordings. However, the recorded data appears to be artifact free and good quality. I'd like to try to roll back to an earlier version. Can you tell me how to do that?

Thanks for your reply. It is indeed strange. We have 3 open ephys set-ups around in the building (different labs) and I heard this sound on one other system before and had no idea why it was happening. We will try to rollback the GUI version and report back to you all.
New headstage, new cable, new port (each tested individually) running newest version 0.5.5.3 did not help the situation. There is popping which you can hear in this video: https://www.dropbox.com/s/sgs4ehctngqv35f/popping_OEv553_2021-12-14_11-43-42-949_.mp4?dl=0
Here is a video showing both popping and fading in / fading out of sound. https://www.dropbox.com/s/q6wgjluj4eco9ps/fadeout_20Off_20tap_20off_OEv553_2021-12-14_11-56-49-321_.mp4?dl=0
From time = 20 sec to 40 sec, we are repetitively tapping lightly on the rat’s back, which should generate a multi-unit response; however, the tapping causes a fading out of the sound which gradually recovers after the tapping stops. It also makes the popping louder. But, note that the popping gets louder during the tapping but it is not synchronized with the tapping. The popping also occurs in the first video when there is no tapping.
Now we rolled back to version 0.5.4. Everything is back to normal. Here is a video. We do the tapping from time = 10 sec to 20 sec.
We didn’t try other versions, but I think we had 0.5.5.1 earlier and it was also OK. The problem may have just been with 5.5.3.
So, it is good that we solved the problem. Let me know if we can do anything to help figure out what happened.
