For example, when the multiple line-outs are present, it adds 598 * the channel suffix like "Front", "Surround", etc (only when @cfg is given). 599 * If no unique name with a suffix is available and @indexp is non-NULL, the 600 * index number is stored in the pointer. 601 */ 602 int snd_hda_get_pin_label(struct hda_codec *codec, hda_nid_t nid, 603 const struct auto_pin_cfg *cfg, 604 char *label, int maxlen, int *indexp) 605 { 606 unsigned int def_conf = snd_hda_codec_get_pincfg(codec, nid); 607 const char *name = NULL; 608 int i; 609 bool hdmi; 610 611 if (indexp) 612 *indexp = 0; 613 if (get_defcfg_connect(def_conf) == AC_JACK_PORT_NONE) 614 return 0; 615 616 switch (get_defcfg_device(def_conf)) { 617 case AC_JACK_LINE_OUT: 618 return fill_audio_out_name(codec, nid, cfg, "Line Out", 619 label, maxlen, indexp); 620 case AC_JACK_SPEAKER: 621 return fill_audio_out_name(codec, nid, cfg, "Speaker", 622 label, maxlen, indexp); 623 case AC_JACK_HP_OUT: 624 return fill_audio_out_name(codec, nid, cfg, "Headphone", 625 label, maxlen, indexp); 626 case AC_JACK_SPDIF_OUT: 627 case AC_JACK_DIG_OTHER_OUT: 628 hdmi = is_hdmi_cfg(def_conf); 629 name = hdmi ?
