Doug Goldstein	888275e66c	alsactl: sprintf to snprintf prevent buffer overflow ... sprintf() is a bit dangerous unless you explicitly know your type size and want to keep it in sync always. Its safer to just use snprintf() and ensure your string doesn't overflow and is NULL terminated.

Jaroslav Kysela	95788fea25	alsactl: Fix the string size for the lock file contents ... The string length is 10 characters + LF + '\0' = 12 characters. Signed-off-by: Jaroslav Kysela <perex@perex.cz>	2013-04-15 14:44:13 +02:00
Jaroslav Kysela	cc5c3357cf	alsactl: add the daemon mode ... For the plug-and-play hardware, like USB devices, it may be helpful to manage the sound state periodically, before the devices are removed. This change implements new commands 'daemon' and 'rdaemon' to save the sound state in defined intervals when the sound controls are changed. The udev rules can notify the daemon using the 'kill' or 'nrestore' commands to rescan available cards in the system. Signed-off-by: Jaroslav Kysela <perex@perex.cz>	2013-04-05 13:47:18 +02:00
