Sound only on 1 channel, plus other quirks post snd_hda import
I am running RELENG_7 from 12 Jan, I noticed that I am only getting sound on 1 channel. Also opening up "Volume Control" from Gnome and altering either of "Volume" or "PCM" produces crackles on the non functioning channel, and kills susbsequent sound output on either channel! (Just to be sure I tried the speakers out with another machine, and they work fine - both channels) I have hw.snd.maxautovchans=2 set in /etc/sysctl.conf - I'm wondering if that is wrong these days. $ dmesg|grep -i hda hdac0: <VIA VT8251/8237A High Definition Audio Controller> mem 0xff5fc000-0xff5fffff irq 17 at device 1.0 on pci2 hdac0: HDA Driver Revision: 20081226_0122 hdac0: [ITHREAD] hdac0: HDA Codec #0: Analog Devices AD1986A hdac0: hdac_widget_connection_parse: nid=18 WARNING: zero cnid entnum=4 j=2 index=0 entries=8 found=2 res=0x21002211 pcm0: <HDA Analog Devices AD1986A PCM #0 Analog> at cad 0 nid 1 on hdac0 pcm1: <HDA Analog Devices AD1986A PCM #1 Digital> at cad 0 nid 1 on hdac0 hdac0: <VIA VT8251/8237A High Definition Audio Controller> mem 0xff5fc000-0xff5fffff irq 17 at device 1.0 on pci2 hdac0: HDA Driver Revision: 20081226_0122 hdac0: [ITHREAD] hdac0: HDA Codec #0: Analog Devices AD1986A hdac0: hdac_widget_connection_parse: nid=18 WARNING: zero cnid entnum=4 j=2 index=0 entries=8 found=2 res=0x21002211 pcm0: <HDA Analog Devices AD1986A PCM #0 Analog> at cad 0 nid 1 on hdac0 pcm1: <HDA Analog Devices AD1986A PCM #1 Digital> at cad 0 nid 1 on hdac0 hdac0: <VIA VT8251/8237A High Definition Audio Controller> mem 0xff5fc000-0xff5fffff irq 17 at device 1.0 on pci2 hdac0: HDA Driver Revision: 20081226_0122 hdac0: [ITHREAD] hdac0: HDA Codec #0: Analog Devices AD1986A hdac0: hdac_widget_connection_parse: nid=18 WARNING: zero cnid entnum=4 j=2 index=0 entries=8 found=2 res=0x21002211 pcm0: <HDA Analog Devices AD1986A PCM #0 Analog> at cad 0 nid 1 on hdac0 pcm1: <HDA Analog Devices AD1986A PCM #1 Digital> at cad 0 nid 1 on hdac0
