Hello, I mounted a htpc with the new micros Ryzen 3 vega 2200G, everything works very well with Debian 9.4 stretch and with mate desktop, the sound card, incorporated in the base card is Realtek ALC 892. When I look at what card I have I get: Advences micro devices, INC. AMD / ATI device 15 dd and 15e3, and in gnome program: Press Gnome audio I get a tab with ATI R6xx HDMI with options to mark IEC 958. I tried all the possible configurations with Alsa and Pulseaudio, if I put Aplay -l I get an analog output for ALC 892 and 5 HDMI Cards without driver then The analog output works for me, but not for HDMI. There are no drivers for this type of AMD built-in graphics, for Linux, only for Windows. The asRock manufacturer of the base card, and those of AMD tell me to install Windows. I refuse to leave Debian. I do not get output through HDMI, It's an htpc, I use it with the TV screen. Somebody could help me. I would be very grateful.
