snd_hda_check_board_codec_sid_config - compare the current codec subsystem ID with the config table

This is important for Gateway notebooks with SB450 HDA Audio where the vendor ID of the PCI device is: ATI Technologies Inc SB450 HDA Audio [1002:437b] and the vendor/subvendor are found only at the codec.

: the HDA codec : number of config enums : array of model name strings : configuration table, terminated by null entries

Compares the modelname or PCI subsystem id of the current codec with the given configuration table. If a matching entry is found, returns its config value (supposed to be 0 or positive).

If no entries are matching, the function returns a negative value.

int snd_hda_codec_reset ( struct hda_codec * codec )

snd_hda_codec_reset - Clear all objects assigned to the codec : HD-audio codec

This frees the all PCM and control elements assigned to the codec, and clears the caches and restores the pin default configurations.

When a device is being used, it returns -EBSY. If successfully freed, returns zero.

snd_hda_ctl_add - Add a control element and assign to the codec : HD-audio codec : corresponding NID (optional) : the control element to assign

Add the given control element to an array inside the codec instance. All control elements belonging to a codec are supposed to be added by this function so that a proper clean-up works at the free or reconfiguration time.

If non-zero is passed, the NID is assigned to the control element. The assignment is shown in the codec proc file.

snd_hda_ctl_add() checks the control subdev id field whether HDA_SUBDEV_NID_FLAG bit is set. If set (and is zero), the lower bits value is taken as the NID to assign. The HDA_NID_ITEM_AMP bit specifies if kctl->private_value is a HDA amplifier value.
