Asus KFSN4-DRE: no Wi-Fi nor sound
I know it's a server board, but I don't understand why my external Wi-Fi key isn't recognised with Wicd or sudo ifconfig (supposedly supported, a TP-LINK WN722N, Atheros version).
Ethernet works, but I don't see it in sudo ifconfig either??
As for the sound, in qjackctl I have a "system" device listed on a working PC, but here there's nothing.
My external USB soundcard is listed in alsamixer though.
The interfaces are not in /etc/network/interfaces.
Minimal install is a bit too minimal sometimes.
I added them, rebooted, and sudo ifconfig still doesn't display anything about wlan0.
There's no eth0, but there's a line for a hot-plugged ethernet already.
As for the sound, no idea.
OTOH, ifconfig works without sudo on my other machine.
Why? What changed?

I bought the wrong version. Version 2 isn't using Atheros.
The vendor indicated Atheros, but I guess I should have confirmed it.
Alsamixer only lists the GPU as a sound device.
When I plug my external sound card, it's also listed,
but... I'll get some more precise data.
Super odd: in Audacious, instead of default pcm in the parameters, I selected one of the lines named after my external soundcard and I got sound output.
Now I restart qjackctl, and it doesn't fail.
I don't understand.
In alsamixer, I have no levels of volumes displayed, and I can't mute any channel.
Next, I close Audacious, open it again and it fails.
I suppose I need to configure default_pcm.
I pretty much did all the checks I could find, but I still have issues with alsa.
I'll try to set up my external soundcard as the default one and hope for the best.
When jack is on, it is normal that alsa can't work.
Jack works with configured programs.
In theory, it means that alsa works through jack only (need to confirm).
But when jack is off, alsa doesn't work.
The simplest way is to just use jack, but alsa alone still seems broken, and I don't like it.
I also did this:
* https://wiki.archlinux.org/index.php/Jack#Playing_nice_with_ALSA
* I'm in the audio group
* my card is unmuted in alsamixer
* I installed the OSS module, just in case
One possibility is that the hdmi from the GPU (considered as the default soundcard) might block something.
Even after blacklisting the default card (and a proper poweroff, then reboot), alsa still doesn't work by itself, but only through jack.
I modified /etc/modprobe.d/blacklist.conf as:
blacklist snd_hda_intel
I also tried from https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture
pcm.!default {
type hw
card USB
}
ctl.!default {
type hw
card USB
}
Finally fixed :D !!!
Not sure the blacklisting is useful though.
