# @AudiodevPerDirectionOptions:
#
# General audio backend options that are used for both playback and
# recording.
#
# @mixing-engine: use QEMU's mixing engine to mix all streams inside QEMU and
# convert audio formats when not supported by the backend. When
# set to off, fixed-settings must be also off (default on,
# since 4.2)
#
# @fixed-settings: use fixed settings for host input/output. When off,
# frequency, channels and format must not be
# specified (default true)
#
# @frequency: frequency to use when using fixed settings
# (default 44100)
#
# @channels: number of channels when using fixed settings (default 2)
#
# @voices: number of voices to use (default 1)
#
# @format: sample format to use when using fixed settings
# (default s16)
#
# @buffer-length: the buffer length in microseconds
#
# Since: 4.0
