<dl class="Bl-tag">
<dt id="hw.snd.pcm_d.latency_timer"><var class="Va">hw.snd.pcm%d.latency_timer</var></dt>

most popping and crackling issues (especially on VIA motherboards).</dd>
<dt id="hw.snd.pcm_d.spdif_enabled"><var class="Va">hw.snd.pcm%d.spdif_enabled</var></dt>

<dd>Experimental polling mode, where the driver operates by querying the
device state on each tick using <a class="Xr">callout(9)</a>. Polling is
disabled by default. Do not enable it unless you are facing weird
interrupt problems or if the device cannot generate interrupts at
all.</dd>
