Audiochip

The model of the audio chip (a module for processing and outputting sound) installed on the motherboard. Data on the exact name of the sound chip will be useful when looking for detailed information about it.

Modern "motherboards" can be equipped with fairly advanced audio modules, with high sound quality and extensive features, which makes them suitable even for gaming and multimedia PCs (although professional audio work will still most likely require a separate sound card). Here are the most popular modern audio chips: Realtek ALC887, Realtek ALC892, Realtek ALC1150, Realtek ALC1200, Realtek ALC1220, Realtek ALC4050, Realtek ALC4080, Supreme FX.
