for DAC settings

The real issue is not with DAC selection. This is rather PCI Latency
Timer issue, which is too flexible for snd_es137x. Try to increase its
latency timer value for pcm0 (128 is a good start) using pciconf(8),
or this tool:
http://people.freebsd.org/~ariff/utils/pcilattimer
There is a hidden kernel hint for this, that is
hint.pcm.<dev>.latency_timer . Set appropriately using kenv(8) and
reload the driver or through /boot/device.hints (require reboot).
