Should I provide > anything more ? > = Following the advice of Paul Menzel I did a "diff" of the sources of the 2.6.32.9 kernel and of the 2.6.33. In patch_realtek.c, we see that there is an new snd_hda_jack_detect funtion with 2 arguments. I have noticed that the second argument is "normaly" the second argument of snd_hda_codec_read. In the alc269_speaker_automute function there is this new snd_hda_jack_detect function, but the second argument is "nid". But in the old alc269_speaker_automute of the 2.6.32.9 the second argument of snd_hda_codec_read is 0x15. So I think there is perhaps a bug here...But I hesitate to modify the source...so I'm waiting the anwser of the dev. --- patch_realtek.c 2010-02-27 14:58:06.000000000 +0100 +++ patch_realtek_modif.c 2010-02-27 14:58:54.000000000 +0100 @@ -13381,7 +13381,7 @@ unsigned int present; unsigned char bits; - present =3D snd_hda_jack_detect(codec, nid); + present =3D snd_hda_jack_detect(codec, 0x15); bits =3D present ?
