Internal CD/DVD recorder,player

Volumio 3 Issues?

I am relatively new to VOLUMIO / LINUX> I installed and configured VOLUMIO streamer onto an unused (previous WINDOWS 7) Lenovo laptop . The VOLUMIO OS is seated and boots from the original HDD.
All functions appear to working A OK. I am in a sense ‘very impressed’ with this system.
I searched various docs in this community and I cannot find an answer or appropriate guide to this install. I wish to use the integrated CD /DVD player to use on occasion when not streaming +/or WEBRadio.
I’m sure it can be accomplished but where to start ?
Thx, Ihor
