The procedure to install a sound server named PulseAudio on a ChromeOS device, which typically uses a different audio system, involves enabling Linux support (Beta) within ChromeOS. PulseAudio is a sound server system for POSIX and Win32 systems. It is a networked sound server, and a replacement for Enlightened Sound Daemon (EsounD). This installation modifies the default audio handling to allow for greater flexibility and control over audio routing and processing.
Installing PulseAudio can be beneficial for users who require advanced audio configurations, such as connecting to Bluetooth devices that are not natively supported, routing audio streams between applications, or applying audio effects. Historically, ChromeOS has had limitations in its audio subsystem, prompting users to seek alternative solutions like PulseAudio to overcome these restrictions and enhance their audio experience. The ability to manage audio in a more granular way significantly expands the functionality of the ChromeOS device.
