My background info: I have not only an archive of analog tape video records, but also a bunch of 30 years archived analog music audio to digitize. To mime, my audio records mainly started when I bought my first reel tape recorder, Tandberg 1200X about 1970 (my first own earned money), in parallell with some vinyl LPs. https://www.audio-high-store.com/tandberg-1200x/ Later on followed also the popular music compact casette deck period for home and in cars. So far I have just ripped audio music tracs from audio CD and DVD discs to mp3 files on my Linux workstation, using K3b or other suited applications. Indeed, I have just started to look at how to digitize and record analog audio from external connected tape and vinyl players. Analog PC connections Analog AUX ports (3,5 mm Jacks or RCA phono connections) labeled "Line IN" (usual on previous internal sound cards), are  have more or less left out on modern workstations and laptops with digital USB ports. However, my most relevant workstation with a MSI Z170A Pro maiboard includes an AUX "Line IN" jack (Light Blue color code) on its backpanel, see attached image if allowed. I am in doubt and have not yet been able to verify or test with analog players if this (Blank: empty?) Jack Line-IN works at all. I think I read on a forum another user had issues with similar. While Audacity didn't find it, possibly the Pulse Audio Volum control (pavucontrol) could enable the Jack Line-IN. If Jack-IN on the mobo back panel won't work, the other option is to find and buy an analog to USB audio interface adapter that works well with Linux. Meanwhile, possibly experience and suggestion to test procedure for this will be welcome ?! ----------------- Some related output from my workstation: inxi -Fxz System:   Kernel: 5.3.18-59.19-default x86_64 bits: 64 compiler: gcc v: 7.5.0   Desktop: Gnome 3.34.5 Distro: openSUSE Leap 15.3 Machine:   Type: Desktop System: MSI product: MS-7971 v: 1.0 serial: N/A   Mobo: MSI model: Z170-A PRO (MS-7971) v: 1.0 serial: <filter>   UEFI: American Megatrends v: 1.K0 date: 07/10/2018 Audio:   Device-1: Intel 100 Series/C230 Series Family HD Audio   vendor: Micro-Star MSI driver: snd_hda_intel v: kernel bus ID: 00:1f.3   Device-2: NVIDIA GK208 HDMI/DP Audio vendor: ASUSTeK driver: snd_hda_intel   v: kernel bus ID: 01:00.1   Device-3: Microdia Camera type: USB driver: snd-usb-audio,uvcvideo   bus ID: 1-11:3   Sound Server: ALSA v: k5.3.18-59.19-default Drives:   Local Storage: total: 5.19 TiB used: 2.87 TiB (55.4%)   ID-1: /dev/nvme0n1 vendor: Samsung model: MZVPV512HDGL-00000   size: 476.94 GiB   ID-2: /dev/sda vendor: Intel model: SSDSA2CW160G3 size: 149.05 GiB   ID-3: /dev/sdb vendor: Seagate model: ST3500418AS size: 465.76 GiB   ID-4: /dev/sdc vendor: Seagate model: ST3500418AS size: 465.76 GiB   ID-5: /dev/sdd type: USB vendor: Seagate model: Expansion size: 3.64 TiB   ID-6: /dev/sdj type: USB vendor: SanDisk model: Ultra size: 28.97 GiB Selected references: https://www.linux-magazine.com/Issues/2018/206/Digitizing-Analog-Music-Media https://ro-che.info/articles/2017-07-21-record-audio-linux https://kimbriggs.com/computer/record-digitize-cassette-ubuntu-linux https://opensource.com/life/14/10/how-clean-digital-recordings-using-audacit...
