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 audio/audio.c | 15 +++++++++++++-- audio/audio.h | 6 ++++-- audio/mixeng.h | 6 ++++-- audio/paaudio.c | 9 +++++++-- hw/audio/ac97.c | 4 ++-- hw/audio/hda-codec-common.h | 2 +- hw/audio/hda-codec.c | 12 ++++++++++-- hw/audio/lm4549.c | 2 +- hw/audio/wm8750.c | 18 ++++++++++++------ hw/display/xlnx_dp.c | 3 ++- hw/usb/dev-audio.c | 6 ++++-- 11 files changed, 60 insertions(+), 23 deletions(-) -- 2.18.1
