GoKawiilDedicated PC sound cards become niche as motherboard audio and USB improve
Modern Windows, Mac and Linux PCs now handle audio processing through integrated motherboard chips, commonly Realtek components, rather than separate sound cards. High-quality lossless audio, including 24-bit/192kHz Dolby Atmos streams, can be transmitted over USB 3.x, DisplayPort, Wi-Fi or HDMI without the bandwidth constraints that once necessitated dedicated hardware.
GoKawiil's interpretation of the reporting above, not reported fact.
The shift suggests sound cards are becoming largely obsolete for mainstream users, as integrated chips and modern data interfaces now handle what once required dedicated expansion cards. Thinner laptops and handhelds benefit from freed-up internal space, while desktop builds avoid extra power draw and airflow restrictions from graphics-card-dominated cases. Professional audio use cases may still favor external solutions, since internal PC components can introduce signal interference that shielding only partially mitigates.
- Integrated motherboard audio chips like Realtek have largely replaced dedicated sound cards in consumer PCs.
- Modern interfaces such as USB 3.x, HDMI and Wi-Fi can carry lossless high-resolution audio well within their bandwidth limits.
- Space, power and interference concerns make external or integrated audio solutions preferable to internal sound cards in many builds.
