Mac OS. When I begin a TeamViewer session your software auto-adjusts my computer's sound volume to 100%. Since I use a headset, once I quit Team Viewer, the next sound I encounter will be at absolute full freaking volume. That said, even at 100% volume it is difficult for me to hear certain customers. Would there happen to be an older version of TeamViewer that I can fall back to that would avoid this issue? If not then I would like to humbly offer my best wishes for a fix to this problem that has existed now for an very unreasonable amount of time. Please fix this issue before my eardrums melt and leak out of my bloody head. Thank you very kindly and have a great day.
