This patch proposes virtio specification for new virtio sound device. Any feedback would be greatly appreciated. Previous version of the proposal: [1].
Reference implementation is now available and located here: * QEMU v4.1.0-rc3 device: https://github.com/OpenSynergy/qemu/tree/virtio-snd-draft * Linux kernel 5.2-rc7 driver: https://github.com/OpenSynergy/linux/tree/virtio-snd-draft How to use: 1) Set the SND_VIRTIO configuration option in Linux kernel config to enable virtio-snd in a guest. 2) QEMU command line must contain virtio-snd-pci device configuration: a) ALSA backend: -audiodev id=sndbe,driver=alsa,out.try-poll=off,\ -device virtio-snd-pci Polling mode must be disabled because QEMU will freeze until playback is stopped. b) PulseAudio backend: -audiodev id=sndbe,driver=pa,server=/run/user/1000/pulse/native,\ -device virtio-snd-pci [1]: https://lists.oasis-open.org/archives/virtio-dev/201905/msg00013.html Signed-off-by: Anton Yakovlev <[email protected]> Signed-off-by: Mikhail Golubev <[email protected]> Please mind our privacy notice<https://www.opensynergy.com/datenschutzerklaerung/privacy-notice-for-business-partners-pursuant-to-article-13-of-the-general-data-protection-regulation-gdpr/> pursuant to Art. 13 GDPR. // Unsere Hinweise zum Datenschutz gem.
