The standard capture source has front mic at 0x3 while the 6stack capture source has front mic at 0x1; this is the only difference but this seems to be what makes it work, I don't know why. (Btw: It is always front mic, no matter what microphone I use. As soon as I plug the external mic the internal one gets muted and the external one takes over it's channel) About the technical stuff: I don't know what an unsolicited event or a VREF is, I'm not a programmer. I just fiddled around with stuff until it was working but don't understand it :) I have uploaded the output of alsa-info.sh twice. First with normal alsa und then with my patch (don't know is this is important) http://pastebin.com/f22f73445 http://pastebin.com/f4a7b49d7 > > > > > > Questions: > > Is this patch any good or is there a better way to fix my problems? > > Why is the recording so quiet and why can't I record with capture value > > above 40? > > > > > > > > Patch: > > diff -r c4c5e6ced12f pci/hda/patch_realtek.c > > --- a/pci/hda/patch_realtek.c Wed Feb 06 15:48:06 2008 +0100 > > +++ b/pci/hda/patch_realtek.c Wed Feb 06 15:59:28 2008 +0100 > > @@ -2917,7 +2917,7 @@ static struct snd_pci_quirk alc880_cfg_t > > SND_PCI_QUIRK(0x161f, 0x203d, "W810", ALC880_W810), > > SND_PCI_QUIRK(0x1695, 0x400d, "EPoX", ALC880_5ST_DIG), > > SND_PCI_QUIRK(0x1695, 0x4012, "EPox EP-5LDA", ALC880_5ST_DIG), > > - SND_PCI_QUIRK(0x1734, 0x107c, "FSC F1734", ALC880_F1734), > > + SND_PCI_QUIRK(0x1734, 0x107c, "FSC F1734", ALC880_FUJITSU), > > SND_PCI_QUIRK(0x1734, 0x10ac, "FSC", ALC880_UNIWILL), > > SND_PCI_QUIRK(0x1734, 0x10b0, "Fujitsu", ALC880_FUJITSU), > > SND_PCI_QUIRK(0x1854, 0x0018, "LG LW20", ALC880_LG_LW), > > @@ -3161,7 +3161,7 @@ static struct alc_config_preset alc880_p > > .dig_out_nid = ALC880_DIGOUT_NID, > > .num_channel_mode = ARRAY_SIZE(alc880_2_jack_modes), > > .channel_mode = alc880_2_jack_modes, > > - .input_mux = &alc880_capture_source, > > + .input_mux = &alc880_6stack_capture_source, > > .unsol_event = alc880_uniwill_p53_unsol_event, > > .init_hook = alc880_uniwill_p53_hp_automute, > > }, > > _______________________________________________ > > Alsa-devel mailing list > > Alsa-devel@xxxxxxxxxxxxxxxx > > http://mailman.alsa-project.org/mailman/listinfo/alsa-devel > > > _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
