On my Windows 7 Laptop, sound recently stopped working in WMP/VLC/MPC/iTunes/QuicMPCkTime, however, sound continues to work in chrome, firefox and IE. dxdiag reports no errors.
My sound card is a Realtek HDA card. (However, it was working a month ago).
- dxdiag gives no errors
- MPC-HC says it's playing, but doesn't actually play
- Windows Media Player says "Windows Media Player encountered a problem while playing the file."
- VLC says it's playing, but consulting the "messages" area gives this: http://pastebin.com/qL44n92w
- QuickTime says it's playing, but doesn't.
- iTunes refuses to play
Whereas, if I open the same media file in chrome or firefox, it plays perfectly.
Just to clarify, no media players show up in Sound Settings at all. I can't unmute/mute them because they're not there.
