Hi Ariff :)
For a month or so I've been using your binary blob,
sndkld_releng6_i386_lowlatency_20070426.tar.gz . It worked great, ( and so did
previous releases - thanks so much!)
( date in filename seems strange, as all the files are dated between 4th and
7th of May 07)
My sound card is :
pcm0 at pci0:27:0: class=0x040300 card=0x05b71014 chip=0x26688086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82801FB/FR/FW/FRW Intel High DefiNition Audio Controller'
class = multimedia
It is detected in dmesg as :
pcm0: <HDA Codec: Analog Devices AD1981HD>
pcm0: <HDA Driver Revision: 20070505_0044>
4 1 0xc0907000 13be0 snd_hda.ko
5 2 0xc091b000 3dadc sound.ko
Anyway, a few days ago I upgraded my kernel + world to -STABLE:
FreeBSD ayiin.octantis.com.au 6.2-STABLE FreeBSD 6.2-STABLE #1: Sat May 26

which includes its own snd_hda :). Now, this version of the module (the one
included in /usr/src, basically), outputs choppy sound when under high cpu
load. It also seems to be doing small chirps every now and then (Very
strange :D ).
I replaced all the s*nd*.ko from -stable with your binary files and it all
works sweet again.
I haven't done any particular configuration , other than :
Is there anything I can do to help figure out what the problem is?
