[alsa-devel] chmod with USB sound device?

[william estrada]

Harald,

   I revisited /etc/security/console.perms.d/50-default.perms
and got it to work.
   For the list, I changed:
     In /etc/security/console.perms.d/50-default.perms
> # permission definitions
.
> <console>  0666 <sound>      0666 root
   And
     In /etc/udev/rules.d/50-udev.rules
> KERNEL=="snd/*",		MODE="0666", OWNER="wre00:root"
   Then I did the udevtrigger.

   Then i did the udevtrigger, plugged in my USB sound device and got this:

> [root at laptop wre00]# ls -lrt /dev/snd
> total 0

> crw-rw-rw- 1 wre00 root 116, 9 Oct 10 10:28 controlC1


   I guess both changes are required but it now works.

   Thanks for your time.
