I have found one old bug with help of your dmesg. On some codecs inter-channel signal leakage was possible. It is not so visible now as we have no real multichannel support, but it may affect sound quality. Problem is here: pcm0: nid=28 [pin: Line-out (Jack)] pcm0: | pcm0: + <- nid=22 [audio mixer] [src: pcm] pcm0: | pcm0: + <- nid=16 [audio output] [src: pcm] pcm0: + <- nid=37 [audio output] [src: pcm] pcm0: pcm0: nid=29 [pin: Headphones (Jack)] pcm0: | pcm0: + <- nid=22 [audio mixer] [src: pcm] pcm0: | pcm0: + <- nid=16 [audio output] [src: pcm] pcm0: + <- nid=37 [audio output] [src: pcm] Signals from nids 16 and 37 should not be mixed. Could you please test attached patch to check how does it help? It works fine on my test setup and I just want to be sure. -- Alexander Motin --------------040507030107080605080404 Content-Type: text/plain; name="hdac.c.crossch.patch" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="hdac.c.crossch.patch" --- hdac.c.prev 2009-01-08 21:26:32.000000000 +0200 +++ hdac.c 2009-01-10 12:25:50.000000000 +0200 @@ -83,7 +83,7 @@ #include "mixer_if.h" -#define HDA_DRV_TEST_REV "20081226_0122" +#define HDA_DRV_TEST_REV "20090110_0123" SND_DECLARE_FILE("$FreeBSD: src/sys/dev/sound/pci/hda/hdac.c,v 1.85 2008/12/27 11:00:20 mav Exp $"); @@ -5479,7 +5479,7 @@ hdac_audio_disable_crossas(struct hdac_d struct hdac_audio_ctl *ctl; int i, j; - /* Disable crossassociatement connections. */ + /* Disable crossassociatement and unwanted crosschannel connections. */ /* ... using selectors */ for (i = devinfo->startnode; i < devinfo->endnode; i++) { w = hdac_widget_get(devinfo, i); @@ -5497,7 +5497,10 @@ hdac_audio_disable_crossas(struct hdac_d cw = hdac_widget_get(devinfo, w->conns[j]); if (cw == NULL || w->enable == 0) continue; - if (w->bindas == cw->bindas || cw->bindas == -2) + if (cw->bindas == -2) + continue; + if (w->bindas == cw->bindas && + (w->bindseqmask & cw->bindseqmask) != 0) continue; w->connsenable[j] = 0; HDA_BOOTHVERBOSE( @@ -5516,7 +5519,8 @@ hdac_audio_disable_crossas(struct hdac_d if (ctl->widget->bindas == -2 || ctl->childwidget->bindas == -2) continue; - if (ctl->widget->bindas != ctl->childwidget->bindas) { + if (ctl->widget->bindas != ctl->childwidget->bindas || + (ctl->widget->bindseqmask & ctl->childwidget->bindseqmask) == 0) { ctl->forcemute = 1; ctl->muted = HDA_AMP_MUTE_ALL; ctl->left = 0; --------------040507030107080605080404--
