[alsa-devel] Linux 2.6.22 and SB-Live! - broken microphone capture?

I have been testing my old SB Live! card with Linux 2.6.22 and the 1.0.14 alsa lib and utils, and
I have discovered that the following no longer works:
$ arecord -f cd -t wav -d 4 > testin.wav
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
arecord: pcm_read:1346: read error: Input/output error
The testin.wav file is always 44 bytes long.
The microphone works, is plugged into the correct slot, and (AFAICT) all the mixer settings are
- playback AC97 = 0
- capture AC97 = 100
- mic select = mic1
- mic set to capture
- capture volume = 100, and set to capture
Has something broken in ALSA, please? Playback seems fine, and I get some kind of noise from the
speakers if I raise the Microphone playback volume to 100 and then blow on the microphone.
I also have an Audigy 2 card, and microphone capture works fine there.
Can anyone confirm this, please?
