The last update of the Raspberry Pi OS in 2020 is here and it looks like it brings some nice improvements, especially around audio and printing. First, the distro is now using PulseAudio as default sound server instead of ALSA (Advanced Linux Sound Architecture). This change alone enables out-of-the-box Bluetooth audio support, adds support for playing sounds from multiple sources at the same time, especially when using HDMI output, lets you switch the sound from HDMI to a USB sound card while a video is playing, and makes it easier to manage the default input and output devices.
