If anyone has any objections, please let us know. ------------------ From: Takashi Iwai commit 43785eaeb1cfb8aed3cf8027f298b242f88fdc45 upstream Don't create mixer volume elements for Headphone and Speaker if they use the same DAC as normal line-outs on AD1988. Otherwise the amp value gets screwed up, e.g. https://bugzilla.novell.com/show_bug.cgi?id=398255 Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela Signed-off-by: Greg Kroah-Hartman --- sound/pci/hda/patch_analog.c | 32 +++++++++++++++++++++----------- 1 file changed, 21 insertions(+), 11 deletions(-) --- a/sound/pci/hda/patch_analog.c +++ b/sound/pci/hda/patch_analog.c @@ -2623,7 +2623,7 @@ static int ad1988_auto_create_extra_out( { struct ad198x_spec *spec = codec->spec; hda_nid_t nid; - int idx, err; + int i, idx, err; char name[32]; if (! pin) @@ -2631,16 +2631,26 @@ static int ad1988_auto_create_extra_out( idx = ad1988_pin_idx(pin); nid = ad1988_idx_to_dac(codec, idx); - /* specify the DAC as the extra output */ - if (! spec->multiout.hp_nid) - spec->multiout.hp_nid = nid; - else - spec->multiout.extra_out_nid[0] = nid; - /* control HP volume/switch on the output mixer amp */ - sprintf(name, "%s Playback Volume", pfx); - if ((err = add_control(spec, AD_CTL_WIDGET_VOL, name, - HDA_COMPOSE_AMP_VAL(nid, 3, 0, HDA_OUTPUT))) < 0) - return err; + /* check whether the corresponding DAC was already taken */ + for (i = 0; i < spec->autocfg.line_outs; i++) { + hda_nid_t pin = spec->autocfg.line_out_pins[i]; + hda_nid_t dac = ad1988_idx_to_dac(codec, ad1988_pin_idx(pin)); + if (dac == nid) + break; + } + if (i >= spec->autocfg.line_outs) { + /* specify the DAC as the extra output */ + if (!spec->multiout.hp_nid) + spec->multiout.hp_nid = nid; + else + spec->multiout.extra_out_nid[0] = nid; + /* control HP volume/switch on the output mixer amp */ + sprintf(name, "%s Playback Volume", pfx); + err = add_control(spec, AD_CTL_WIDGET_VOL, name, + HDA_COMPOSE_AMP_VAL(nid, 3, 0, HDA_OUTPUT)); + if (err < 0) + return err; + } nid = ad1988_mixer_nids[idx]; sprintf(name, "%s Playback Switch", pfx); if ((err = add_control(spec, AD_CTL_BIND_MUTE, name, -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
