BTW, are there boards / machines that have both analog and digital mics? Currently, we have "Digital Capture Volume". It was introduced as an alternative volume control for digital mics. But, this seems confusing people a lot because this volume works correctly at 50%, corresponding to 0dB. For systems that have only analog mics, this control doesn't make much sense. Thus, I would love to make this control depending on the presence of digital mic if possible... thanks, Takashi > --- > diff -r 6b53fa114faa pci/hda/patch_sigmatel.c > --- a/pci/hda/patch_sigmatel.c Tue Feb 19 15:03:57 2008 +0100 > +++ b/pci/hda/patch_sigmatel.c Wed Feb 20 17:11:51 2008 -0500 > @@ -3629,6 +3629,8 @@ static int patch_stac927x(struct hda_cod > spec->mixer = stac927x_mixer; > break; > case STAC_DELL_BIOS: > + /* configure the analog microphone on some laptops */ > + stac92xx_set_config_reg(codec, 0x0c, 0x90a79130); > /* correct the front output jack as a hp out */ > stac92xx_set_config_reg(codec, 0x0f, 0x02270110); > /* correct the front input jack as a mic */ > _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
