Audio Dropouts after recent update

[BruceS2]

Similar issue but not exactly the same.  I did a one hour session last night Mac to Mac and it was perfect.  Tonight, joined 2 others, both Windows users with me on the mac.  As we played, after about 4 to 8 measures of a song, one guy's audio dropped out...just a "click" and he is gone.  Video sill good. (tied with no video, same) The other player did not lose him and I could hear the 2nd player..he never dropped out.   He rejoined, same issue.  I reboot, same thing.  Ideas?  Must have happened 10 times tonight with the same guy.  Good latency and perfect sound while it worked. Have played with this group in the with out problems...feels like a bug.
