The device simply does not perform its main function declared by the manufacturer, namely, it does not record sound in PC-FREE mode! To make it more clear: when recording gameplay through it in PC-FREE mode, you will have a video recorded (the gameplay itself, directly) and comments to it if a microphone is connected, but there will be no sound of the game itself! The device, in principle, has problems with connecting and installing drivers, there is no PLUG & PLAY, as it says on the manufacturer's website and is drawn on the box - I spent a day to ensure that an image appeared in the regular ReCentral capture program, t. To. when connected, the program simply did not recognize the connected device!
Addition: The problem with recording sound via hdmi connection was solved by an adapter from HDMI to VGA (that is, we connect the card to the monitor via an analog input so that the path, in general, does not look for sound at all). The fact is that the GPU, when connected through this card, sees a monitor without speakers at the end of the cable as an output source and flatly refuses to send sound through the cable, and by connecting the card to the monitor via VGA through an adapter, we do not let the card understand that the source at the end is not capable of reproducing sound . Of course, this is an engineering miscalculation. Finally, after a week and a half, or two weeks, the offline mode worked fully, as it should, when the source is a PC. It's very sad that you had to come to everything yourself. Support services, we can now say with complete confidence, no! I attached their response to this review and it speaks for itself! Someone casually mentioned the analog connection on Reddit. This comment is not specifically noted by anyone, and this is but the only solution to the problem of no sound over HDMI.
