I'm trying to work out how to get PCIE sound cards working with Xpenology installed on my HP N40L Microserver. I've got an Asus Xonar DX 7.1 sound card that I want to use to run Shairport-Sync on for a multi-room setup (ie 8 audio channels -> 4x discrete stereo sound outputs -> 4x pairs configured in ALSA with 4x instances of Shairport-Sync).
As far as I can work out, I just need to follow this guide https://xpenology.club/compile-drivers-xpenology-with-windows-10-and-build-in-bash/ to compile the sound card drivers and all ALSA related components, and inject them in?
I believe Xonar DX is natively supported in Linux 2.6+ and ALSA, so it should work?
Is there anything else that I need to do to my Xpenology install to get ALSA and the sound card drivers installed and working?
