No,  only those creative sound card emu10k1 and ca0106 allow up to four pcm
devices

For hda,  you need to change the logic of alsa playback stream similar to
multiple alsa capture devices,  you can use hint "indep_hp=1" to enable
multi stream playback (analog and alt analog playback )

Freebsd allow you to use your hda intel as four independent pcm devices
