I have taken a look under the gitweb : in the commit of the introduction of snd_hda_jack_detect() http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commit;h=864f92be7e8d4a0ba11d912e3f03d1a92a031dee I see : @@ -13183,8 +13098,7 @@ static void alc269_speaker_automute(struct hda_codec *codec) unsigned int present; unsigned char bits; - present = snd_hda_codec_read(codec, 0x15, 0, - AC_VERB_GET_PIN_SENSE, 0) & 0x80000000; + present = snd_hda_jack_detect(codec, 0x15); bits = present ?
