HD audio issue after upgrade to win 10, no HD sound format

Question asked by potta20 on Oct 6, 2015

Hi there.

Recently I have upgraded my os to Windows 10/64bit. After installing Realtek AMD High definition audio driver, in Advanced properties of audio manager I didnt get Studio quality. Trying to update drivers thru Windows device manager did work, but just for a short. Everything works fine for some time and then everything goes wrong - I lose Encoded formats, high Sample bitrates and high quality Default formats in Advanced tab in Properties, leaving only CD and DVD quality.

If I reinstall driver manually it works for some time, and then again, I lose HD audio.

I have HD5570 that is connected to my A/V receiver with HDMI...

Please, I`m losing my mind with this.
