``--alsa-buffer-time=<microseconds>``
Set the requested buffer time in microseconds. A value of 0 skips requesting
anything from the ALSA API. This and the ``--alsa-periods`` option uses the
ALSA ``near`` functions to set the requested parameters. If doing so results
in an empty configuration set, setting these parameters is skipped.
Both options control the buffer size. A low buffer size can lead to higher
CPU usage and audio dropouts, while a high buffer size can lead to higher
latency in volume changes and other filtering.
``--alsa-periods=<number>``
Number of periods requested from the ALSA API. See ``--alsa-buffer-time``
for further remarks.
