I have an older HP system upgraded from Windows 7 to Windows 10, the auto no longer works, using HD audio, driver is loaded, and recognizes when jack is connected, but no audio. I checked and set playback device, output audio format etc. I right click selected playback device and click test and I get 'Failed to pay test tone"
I installed a USB audio device, drivers loaded automatically but exact same result. Tried other pair of speakers, same result.
I ran a SFC /Scannow result said all files are correct
I uninstalled Norton AV, same result.
Anyone got any other ideas?
