NAMEsnd_es137x - Ensoniq AudioPCI ES137x bridge device driver
SYNOPSISTo compile this driver into the kernel, place the following lines in your kernel configuration file:
device sound device snd_es137x
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:
DESCRIPTIONThe sysctl Cm net.inet.tcp.syncookies bridge driver allows the generic audio driver sound(4) to attach to the Ensoniq 137x audio cards.
Runtime ConfigurationThe following sysctl(8) variables are available in addition to those available to all sound(4) devices:
- Controls the PCI latency timer setting. Increasing this value will solve most popping and crackling issues (especially on VIA motherboards).
- Enables S/PDIF output on the primary playback channel. This sysctl(8) variable is available only if the device is known to support S/PDIF output.
- Experimental polling mode, where the driver operates by querying the device state on each tick using callout(9). 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.
