PCI sound cards

PCI

— interface for connecting internal peripherals to the PC motherboard. It is the forerunner of PCIe, has significantly lower bandwidth and more modest features, so it is generally obsolete. Nevertheless, nowadays, motherboards with such connectors and sound cards for the PCI interface (including quite advanced ones) continue to be produced. This is due to the fact that relatively low bandwidth is enough to work with sound; and installing an audio card in the PCI slot leaves PCIe slots free, which may be required for components that are more demanding on connection speed. Anyway, before buying such a sound card, it's ok to make sure that the "motherboard" has a connector for connecting it.
