Set ALSA playback buffer and period size based on time

So rate adjustments won't modify the latency

Always disable ALSA's resampler for playback
...
This means the frequency config option won't have an effect if the ALSA device
can't set an alternate sampling rate

Specify the buffer size to ALSA, so the period count remains flexible
...
Under conditions where the period size is fixed (such as dmix), ALSA will still
attempt to provide the requested number of periods even if the requested period
size needs to be dramatically altered. In these cases, it would be better to
increase or decrease the period count, instead of growing or shrinking the
total buffer size and significantly changing the latency.
