It depends on the audio splitter you choose to use.Having utterly failed to get audio out of USB on my RPi 5 running current PiOS, and sick of the noise and latency of Bluetooth, I thought it might be possible to split things and get video out of one HDMI port and audio from the other. I know I can get an external gadget that does this, but surely someone has cooked up a way to do this in software, right?
There is no such thing as sending only audio over HDMI, so it has to mimic some form of display, and that display be active within the OS.
USB sound cards should be recognised. Has the kernel detected it? "lsusb" will tell you, and I'd then expect "lsmod" to report "snd-usb-audio" to be loaded. "aplay -l" should list it as a sound card.Alternatively, is there a way to get the Pi sound system to recognize USB? The soundbar has a nice built-in DAC for just such a use, but Pi audio doesn't recognize the existence of the Pi's USB ports. Nor a USB connection to the soundbar, which it finds happily via Bluetooth. Installation is stock; did nuke Pulseaudio and have latest Pipewire in the repository. Are there other packages I need to install? Seems as if there might be.
