I have Windows 7 Pro 64 bit SP1 tower, which was built by a local shop years ago. I have the paid for Windows extended updates. Latest one is Security Monthly Quality Rollup for Windows 7 for x64-based Systems (KB5015861), which I installed on 7/27/2022.
I am having a real problem with getting audio from websites and web radio stations that play music or spoken voices. That includes YouTube. There is no sound at all. I have confirmed that my speakers are connected correctly to the tower. I have deleted and reinstalled Windows Media Player (Windows Media Center and Windows DVD maker are also installed). Unfortunately, since I don’t try accessing audio via websites and radio stations very often, I have no idea when this problem started.
But there are exceptions. If I can access the website via VLC Media player, the sound plays. If the website gives me the option to listen via MP3 or RealPlayer, the sound plays. I also have a Sonos system. If I have a radio station that will not play directly, but access that same station via Sonos, the sound plays.
I also have two Windows 10 laptop computers, which have internal speakers. Everything works fine on them.
I have searched the internet, and so far have not found anything that addresses this problem.
Any help or suggestions would be greatly appreciated.
