Exactly. This is what I tried:
dm at schlupp:~$ cat /proc/asound/cards
0 [UA5 ]: USB-Audio - UA-5
EDIROL UA-5 at usb-0000:00:10.0-1, full speed
**unplug device**
dm at schlupp:~$ cat /proc/asound/cards
--- no soundcards ---
** check if there are any procecces still accessing an audio device - only
gnome-settings-daemon **
dm at schlupp:~$ lsof | grep snd
gnome-set 11449 dm 35u CHR 116,0 1025295
/dev/snd/controlC0
dm at schlupp:~$ lsof | grep mixer
gnome-set 11449 dm 34u CHR 14,0 1024941
/dev/mixer (deleted)
**plug device back in and wait a few seconds**
dm at schlupp:~$ cat /proc/asound/cards
--- no soundcards ---
dm at schlupp:~$ killall gnome-settings-daemon
dm at schlupp:~$ cat /proc/asound/cards
0 [UA5 ]: USB-Audio - UA-5
EDIROL UA-5 at usb-0000:00:10.0-1, full speed
** Now I tried something else to make sure I'm not mistaken: I made the two
audio-devices inaccessible for g-s-d.**
dm at schlupp:~$ cat /proc/asound/cards
0 [UA5 ]: USB-Audio - UA-5
EDIROL UA-5 at usb-0000:00:10.0-1, full speed
dm at schlupp:~$ sudo chmod 600 /dev/snd/controlC0
dm at schlupp:~$ sudo chmod 600 /dev/mixer
dm at schlupp:~$ lsof | grep snd
dm at schlupp:~$ lsof | grep mixer
** plug out ***
dm at schlupp:~$ cat /proc/asound/cards
--- no soundcards ---
** plug in **
dm at schlupp:~$ cat /proc/asound/cards
0 [UA5 ]: USB-Audio - UA-5
EDIROL UA-5 at usb-0000:00:10.0-1, full speed
** It worked then. So the two devices being still open are causing the problem.
I had to chmod __both__ devices btw. **
Hope that helps
