[Qemu-devel] [PATCH v4 00/11] apply volume on client side

[Marc-André Lureau]

Hi,

This patch series implements client-side audio volume support. This reduces 
confusion of guest users when volume control is not effective (because mixemu 
is disabled or because client-side is muted and can't be unmuted by the guest..)

Instead, the backend is responsible for applying volume giving the guest 
control over the full range of the client, and avoiding multiple level of 
volume/mute effects.

Although I was mainly interested in having the Spice audio backend support, I 
also added PulseAudio backend support (which unfortunately requires full-blown 
API, even after quick discussion with upstream).

v4:
- code style fixes (only warnings left - mostly spaces)
- dropped the 1 << 32 -1 change
- added QEMU_MIXEMU runtime option, enabled by default
- rfc: removed some deprecated audio options

Marc-André Lureau (11):
  audio: add VOICE_VOLUME ctl
  audio: don't apply volume effect if backend has VOICE_VOLUME_CAP
  hw/ac97: remove USE_MIXER code
  hw/ac97: the volume mask is not only 0x1f
  hw/ac97: add support for volume control
  audio/spice: add support for volume control
  Do not use pa_simple PulseAudio API
  configure: pa_simple is not needed anymore
  Allow controlling volume with PulseAudio backend
  Enable mixemu by default, add runtime option
  audio/rfc: remove PLIVE and PERIOD options
