I'm using on-board audio on mb ROG STRIX X470-F GAMING, video card is pulse rx 5700 xt. If i record with default audio output is hdmi audio there is sound in recordings if my realtek sound is default there is no sound. I found that there is workaround with not installing hdmi audio driver but new driver is missing that feature and installing older driver is not a option cause instability with 5700 series. Support isn't answer more than a day :\
