I am designing a digital microphone that should send PCM (LPCM) data to a PC, and I am new to electronics.
My first thought for the connection type to interface with the PC was of course USB, but then I figured that HDMI is an alternative more suited to digital audio data, and maybe simpler to work with.
But how to get at audio data through HDMI on a Linux system, if it is even possible? I do not mind writing a kernel module if it would not be too complicated.
My CPU is i5-8300H with Intel® UHD Graphics 630.
