I have IDT High Definition Audio Codec installed on my E6420 Dell. When I had Win 7 installed, I was able to direct sound to my speakers. I have the IDT speaker/headphone combination selected as default.
Since I upgraded to Win 10, I am no longer able to get any sound through the speakers (I have the headphone pulled out).
In addition VLC will not play back through the speakers or the headphones.
When I left click on the audio icon, a single slider pot comes up representing the IDT system, but manipulating this makes no difference.
I ran the windows troubleshooter and it fixed some problems, I can now hear Vlc and Skype, and Audacity loaded with no error message, but still no way to get sound through the speakers.
