Thank you for your insight. Probably, after using my Gigabyte GA-MA790FXT-UD5P motherboard for almost 20 years, I indeed should read its manual. :) After all, "if nothing else helps, try to read the manual." :) Will do it in the nearest future, but I doubt that it says something about this issue. However, I think that you are right and the problem lies in the motherboard. By the way, for years, I have had another issue with it that confirms your point of view: if I start my computer with a Logitech USB video camera plugged in, I randomly do not have a sound out. By "randomly" I mean that sometimes the sound out may be present and sometimes not. I have tried everything and even started a thread about it here, but nothing helped. Finally, I used to start my computer without my USB video camera plugged in, and it guarantees the presence of an audio after booting. Additional information: I have AMD/ATI RV740 PRO [Radeon HD 4770] video card plugged into PCIEX16_1 slot and (never used) "brackets", one of which is connected to F_AUDIO and the other is connected to a SATA port. The manual also says that my motherboard has 6 SATA ports working via South Bridge and 4 SATA ports working via another Gigabyte SATA chip. Maybe, I have to experiment with connecting my hard drives to SATA ports in different order...
