Realtek Audio HD Manager does not auto-detect speakers

pyromanta · 28 Oct 2014

Hi all,

I recently updated my AMD drivers as Civ: Beyond Earth asked me to. Since then, the Audio Manager has not been able to detect the speakers automatically.

I regularly plug in and unplug my headset and previously the system would detect it being removed and automatically switch the sound to come out of my monitor (a small TV). For some reason it now switches to Optical out, which I have nothing connected to. Plugging the headset in resets it to Speakers and I can hear sound from the headset.

I can't re-enable Speakers as my playback device as it's listed as 'Not connected' even though it is. The only solution I've found is to completely restart, which I shouldn't have to do every single time I unplug my headset.

I'm going to try disabling all the audio devices on control panel and then restarting to see if it detects the correct ones again. I'll edit here if it works.

Apparently a problem with the AMD drivers. I assume you are connecting via HDMI to the TV.
Roll back the AMD drivers to the previous version and see if that fixes it.

When you are using HDMI, the PC sound, e.g. RealTek is not being used. The sound is generate in the Video Card.

When an HDMI cable is plugged in the Video Card detects that and sets a flag for Windows that HDMI is connected and Windows will automatically make the HDMI the Default Playback device.
