Keep in mind that simply submitting a log file DOES NOT normally result in response to you (other than an automated response that gives the log number). Never intended to.
With that said, I seldom use sound on any of my Wyze cameras, but have never noticed what you are reporting. Just did a test and sound worked fine, but I did notice that at least within a group, it will only let you receive sound on one camera at a time. If you turn on sound on a second camera,the sound will be turned off on the first camera.
