Default Sound issue PC-BSD 9.0 on Lenovo Thinkpad R400
+++++ have submitted the same question into FreeBSD Forums hoping that even more guys with expert hints read it, if this is not the right way pls excuse and tell me so ++++++++


Hi all,

I am happy with FreeBSD and PC-BSD on my 3 systems, however with PC-BSD 9.0 on my Lenovo Thinkpad R400 I don't get sound regardless what I try.
Would be glad if one of you experts have a hint for me!

Situation:

Parameters and tunings I have found in various postings to similar topics, tried out but have erased again as they have not been working in my case are:

/boot/loader.conf:
sound_load="YES"
snd_hda_load="YES"
snd_driver_load="YES"

/etc/sysctl.conf: (also tried with =0 ....)
/hw.snd.default_unit=1

/boot/device.hints:
hint.hdac.0.cad0.nid18.config="as=0"
hint.hdac.0.cad0.nid17.config="as=1 seq=15 device=Headphones"
hint.hdac.0.cad0.nid22.config="as=1 seq=0"


Now, after erasing all these try-and-errors, the cleaned-up-again situation is
as follows:

dmesg:
..
hdac0: <Intel 82801I High Definition Audio Controller> mem 0xfc020000-0xfc023fff
irq 17 at device 27.0 on pci0
..
hdac0: HDA Codec #0: Conexant CX20561 (Hermosa)
pcm0: <HDA Conexant CX20561 (Hermosa) PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA Conexant CX20561 (Hermosa) PCM #1 Analog> at cad 0 nid 1 on hdac0
..

cat /dev/sndstat:
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA Conexant CX20561 (Hermosa) PCM #0 Analog> (play/rec) default
pcm1: <HDA Conexant CX20561 (Hermosa) PCM #1 Analog> (play/rec)

/etc/sysctl.conf:
hw.snd.default_auto=1


BTW the sound is working with other Operating systems so I mean it is not a broken HW...(just wanted to check the basics )
