[pulseaudio-discuss] Missing second HDA playback device

[Jon Smirl]

If I understand this right the reason why
pci_8086_284b_alsa_playback_1 didn't open is because alsa didn't
define any device strings for it.

I loaded snd-hda-intel like this which is the right jack configuration.
options snd-hda-intel model=6stack-digout

My SPDIF on hw:0,1 is missing from the following list.
So it appears that the config files in /usr/share/alsa aren't building
the right device strings.

This looks even more messed up. The USB device is a mic on a camera,
why is it in the aplay list and not in the arecord list? The record
devices on my HDA hardware should be front mic, back mic, line in.

The conclusion is that ALSA is not describing the devices correctly,
right? Now I need to figure out why ALSA didn't get this right when I
told it the jack setup on the module params, model=6stack-digout. The
ALSA hw devices are right, it's these devices from the config files
that are all wrong.
