P.S.:If you aren't the good interlocutor I am sorry to disturb you.
The vt1708 "just works" with recent versions of linux kernels. On my system it calls itself "SB" (soundblaster?)
aplay -l
... card 1: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 card 1: SB [HDA ATI SB], device 1: VT1708S Digital [VT1708S Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 ...
For my particular ALSA usage where I wanted SPDIF output doubled w/ analog output, see "mythcd" and "mythtv" controlling card "SB" in http://nielsmayer.com/npm/dot-asoundrc.txt
Also, some setups (like my ASUS_M4A78T-E mobo ) the vt1708S gives you a additional HDMI device you may never use, yet it uses an interrupt and an ALSA audio device.
## 1 [SB ]: HDA-Intel - HDA ATI SB ## HDA ATI SB at 0xfb7f4000 irq 16 ## 2 [HDMI ]: HDA-Intel - HDA ATI HDMI ## HDA ATI HDMI at 0xfb9fc000 irq 19
It can be disabled (allowing some other ALSA device to be bound to card slot 2) with the following in /etc/modprobe.d/
alias snd-card-1 snd-hda-intel #alias snd-card-2 snd-hda-intel ## ## disable HDMI device to conserve resources and interrupts ## 'modinfo -p snd-hda-intel' indicates this param will do the trick: ## enable:Enable Intel HD audio interface. (array of bool) ## options snd-hda-intel index=1,2 enable=1,0
