![]() Component Required for installing and testing USB Sound Card on Pi Zero This tutorial is the part of our Raspberry Pi Zero series where we are going to install USB sound card in Raspberry Pi zero W and we will use ALSA utilities to test sound card and sound device. The USB sound card or bespoke analogue with an ADC (analog-digital converter) can be used to connect the additional hardware to Raspberry Pi. We all know that the Raspberry pi zero W does not have audio hardware and pin-based PWM situation. A USB sound card along with the microphone is used to add audio capabilities to Raspberry Pi Zero that lacks an audio connector like other Pi versions.
