Apologies if this is a very basic question but I've searched around and can't find the answer.
I have an HTPC running LibreELEC 18.2, set up as part of a small home network. The PC has one internal hard drive and a sound card with a single HDMI socket used to connect it to my amplifier.
Also connected to the amp are a reel-to-reel tape deck and a vinyl-disc turntable; these obviously are not part of the network, but the amp is. Is there a way of transferring audio material from these sources to the HTPC's hard drive? The computer has its own audio in/out sockets but I'm not sure if these are still active or have been disabled by the insertion of the sound card.
I know I could do it via a direct connection with a Windows OS and suitable software, but can it done with LibreELEC/Kodi?
Many thanks in advance for any thoughts.
