I've been trying to get audio recording working properly, with no
success.  Looking through the mail archives, I don't appear to be
the only one.  I'm hoping somebody here can provide me a clue,
cause this works fine under Windows.

I have a laptop with a clct (dmesg follows;
lines wrapped):

    clct0 at pci0 dev 8 function 0: Cirrus Logic CS4281 CrystalClear
	Audio Interface (rev. 0x01)
    clct0: interrupting at irq 10
    clct0: ac97: Crystal CS4297A codec; headphone, 20 bit DAC, 18 bit ADC,
	Crystal Semi 3D
    clct0: ac97: ext id 200<AMAP>
    audio0 at clct0: full duplex, independent

    NetBSD slab 2.0_BETA NetBSD 2.0_BETA (GENERIC_LAPTOP) #0: Fri Jun 25 19:01:50 UTC 2004  autobuild@tgm.netbsd.org:/autobuild/netbsd-2-0/i386/OBJ/autobuild/netbsd-2-0/src/sys/arch/i386/compile/GENERIC_LAPTOP i386

My mixerctl settings have mutes off for everything, and all volumes
are >= 191.

Plain old audiorecord fails:

    $ audiorecord foo.wav
    audiorecord: failed to set audio info: Invalid argument

Recording from /dev/audio seems to do something:

    $ audiorecord -d /dev/audio -t 0:05 foo.wav

But playing it back with audioplay just produces white noise -- it
has some vague pulsing pattern, but it's still just hiss.  I've tried
the mic and line inputs.

I did notice at one point last night that, during a 5 second sample,
my test appeared very momentarily in the middle.  But it was not
clear -- or what I expected.

I've tried using the audio/xwave and audio/dap packages, and they
can't get anything better.

Ideas?   I've attached my `mixerctl -a' and `audioctl -a' settings
below.  Thanks.

Brian.
