Scream is a virtual sound card device driver for Windows that broadcasts audio played on the machine as a PCM multicast stream over the local network. Receiver applications for Linux (PulseAudio/ALSA) and Windows can pick up the stream and play it on remote speakers, with optional IVSHMEM transport for QEMU virtual machines.

Use cases

stream audio from a Windows PC to Linux speakers over the network
get sound out of a Windows VM running on a QEMU host
play Windows audio on a remote machine without cables
set up a virtual network sound card
redirect VM audio to the host via IVSHMEM

When to choose

you need low-latency audio streaming from Windows to another machine on the same LAN
you run a Windows guest in QEMU/KVM and want simple audio passthrough
you want a lightweight multicast-based audio redirect instead of PulseAudio network modules

When to avoid

you need audio streaming over the internet or WAN rather than a local network
you require encryption or authentication on the audio stream
your Windows 10 install cannot load cross-signed kernel drivers and you cannot use the workarounds
