Video, no Audio

[Haze]

Hello

Got recent gremlin in the system, i have my PC hooked up to my AV amp (Yamaha RX-V673) and have recently lost audio, the last couple of weeks i have solved this by rebooting the pc, but today that does not seem to be working either, i can have sound if i select my DAC instead and use my headphones, but no joy through the HDMI, any ideas?

thanks

Probably the Windows audio setting has changed?
