I have a XFX R9 280X 3GB video card. Until yesterday the audio was working through HDMI port. It has now stopped working. No splats on any devices. The devices all show as working properly but no audio. I have tried uninstalling/re-installing the drivers/software for the card and deleting the device from device manager then re-installing. I have tried different ports on my LCD which I am using as my monitor. I have tried rolling back the OS to a restore point prior to this issue occurring, no luck with any of those. has anyone else had a similar experience and if so how did you resolve it?
