Win10, there are speakers on the monitor connected through back panel and headphones through the front. Speakers on the monitor is quiet so there is 100% volume and on headphones 25%. The default settings such that when I pulled out the headphones, which was 25%, the sound machine went on the speakers to 100% and Vice versa when back stuck headphone volume was 25%.
Recently Win10 cheto updated, and now all the same volume. The question is how to get it back?
