Thanks a lot for this information. I'v found a near identical(?) model at an affordable price, Behringer U-Phono UFO202 USB Vinyl Audio interface https://www.behringer.com/product.html?modelCode=P0A12 I wonder if it is possible to record and save audio in FLAC lossless compressed format in any application on Linux?

The Realtec ALC892 audi chip used on your (and may other) motherboards have for input two stereo A/D converters, which can do 16/20/24-bit, and 44.1k/48k/96k/192kHz sample rates. Because the analog front end is specified as 90 dB(A), and 16 bits in itself is 96 dB, there is little point in using more than 16 bits, unless it needs to be mixed with 20 or 24 bit signals. The highest sample rates usually cause a loss in precision, and bandtwith is limited to 22 kHz mostly (I think motherboard determines that).
How this compares to external USB sound cards I don't know, have not looked at measurements. The Behringer UCA202 I once measured, and S/N was 70 dB. Which was way below the noise from the cassettes I digitized, so prefect for this.

I have speakers connected to the back panel audio ports and possibly also a mic. In the meantime thanks for the received suggestion and detailed information.
What is really the "A/D converter" using analog ports in comparision with an usb A/D adapter?
