General informations

The Linux kernel configuration item CONFIG_SND_CTL_DEBUG:

Help text

Say Y to enable the debugging feature for ALSA control API. It performs the additional sanity-checks for each control element read access, such as whether the values returned from the driver are in the proper ranges or the check of the invalid access at out-of-array areas. The error is printed when the driver gives such unexpected values. When you develop a driver that deals with control elements, it's strongly recommended to try this one once and verify whether you see any relevant errors or not.
