Thank you Clemens, sudo setcap cap_sys_rawio... solves the problem :) I only need to ad it to the qt build or to the app itself. Best Regards, Rafal

I would like to access pin verb hda interface using snd_hwdep_open() function. It works fine if I run as root. I hope there is a way to configure my kubuntu so I can do it as non-root user (e.g. debugging) so far, I have been trying changing access flags for devices in /dev/snd/ directory to crwxrwxrwx no plus character. It did not change my privileges for snd_hwdep_open() - still returns –13.
sound/pci/hda/hda_hwdep.c says:
static int hda_hwdep_open(struct snd_hwdep *hw, struct file *file) { #ifndef CONFIG_SND_DEBUG_VERBOSE if (!capable(CAP_SYS_RAWIO)) return -EACCES; #endif return 0; }
