I think it's time to RMA this board to change to another model.
First of all, forgive me for creating a new topic. I have built a PC recently, installed Windows 10, necessary drivers and programs. Then I realized that audio stops for a few seconds randomly every hour/half an hour. It continues working after that automatically. It became annoying quickly. I used different audio cables, different headphones and speakers, installed, updated, uninstalled and reinstalled audio drivers over and over. I have even used speakers without audio drivers. I have disabled audio enchancements. I have updated BIOS thrice. I have clean installed Windows 10. Note that any audio is muted during this period, including sounds from games, songs, videos, Skype calls, and Windows sounds.
I have contacted Gigabyte online support. They couldn't help me. Then I have sent the motherboard to the technical service. They fixed a bent CPU pin (only one pin) and said that the problem is most probably related to that. The problem wasn't fixed, however. I have done further experiments and found out that OBS can record all the sounds during these few seconds. So the audio is created but it can not be transmitted to the speakers. Also CPU usage and temperature don't spike when the audio is muted, so I don't think that it's a CPU-related problem. After all, I encounter the problem even when I'm watching movies sometimes. Can you think of anything? Thanks already.
