Dear Elimar,


Sorry for the late reply. I ran some more tests.

Just starting the system to the graphical login manager (LightDM, 
lightdm-gtk-greeter) no sound cards are detected, and no sound can be 
played (MPlayer outputs `Audio device got stuck!`) when logging in over SSH.

```
$ aplay -l
aplay: device_list:268: no soundcards found...
```

As soon as I log into a graphical session, sound devices are detected 
and I can play sound with no problem.

```
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VB Analog [ALC269VB Analog]
   Subdevices: 0/1
   Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]

```
$ sudo alsactl init
alsactl: sysfs_init:48: sysfs path '/sys' is invalid

Found hardware: "HDA-Intel" "Realtek ALC269VB" 
"HDA:10ec0269,10280577,00100100 HDA:80862806,80860101,00100000" "0x1028" 
"0x0577"
Hardware is initialized using a generic method
$ echo $?
99
$ ls -l /var/lib/alsa/
total 0
```

So that didn’t seem to have worked.

```
$ sudo alsactl store
$ ls -l /var/lib/alsa/
total 12
-rw-r--r-- 1 root root 9233 Dec 19 17:23 asound.state
```

After restarting the system, the udev error message is gone, as expected.

But functionality wise, nothing changed. Until I log in in the graphical 
session no sound devices are found.

```
$ ls -l /var/lib/alsa/asound.state
-rw-r--r-- 1 root root 9233 Dec 19 17:23 /var/lib/alsa/asound.state
$ aplay -l
aplay: device_list:268: no soundcards found...
```


Kind regards,

Paul
