[Qemu-devel] [PATCH 0/3] Allow hw/audio drivers to pass raw DB values to audio/ drivers

[Yaroslav Isakov <yaroslav.isakov@gmail.com>]

This patch series introduces the ability for virtual audio drivers to pass
information about guest-chosen DB values to backend audio drivers.

For now, supported virtual driver is hda-codec, and backend is pulseaudio, as
they both support DB values.

Without these patches, emulated Windows has a very short range of hearable
sound, as range in the guest is much smaller than in Pulseaudio.

Yaroslav Isakov (3):
  Allow audio driver to pass DB value to underlying drivers
  Pass raw DB values from hda-codec.c to audio driver
  If raw DB values are known, use them in paaudio
