Microfone input on snd_ich disabled? (5.3-BETA4)

[dsw]

Hi all,

Just been testing a known working microfone in my Asus P4800E-based box,
with various recording programs, with no luck.  It just seems dead.  The
microfone device is actually alive hardware-wise, as there is a windows
partition on this box, and that works.

pcm0: <Intel ICH5 (82801EB)> port 0xee80-0xeebf,0xe800-0xe8ff mem 0xfebfb400-0xfebfb4ff,0xfebfb800-0xfebfb9ff irq 17 at device 31.5 on pci0
pcm0: [GIANT-LOCKED]
pcm0: <Analog Devices AD1985 AC97 Codec>


'mixer' settings are fine, (rec,mic,etc..) all at ~75, and recording source is
'mic'. I have two inputs, line-in and mic, and i've tried both (obviously
setting 'line' to a ~75 mark, too.)

I've checked some archives, and a few others with similar setups have this 
problem.  I found one with a mention of a patch, of which i added the diffed
code to ac97.c to take advantage of the mentioned 20dB gain increase, but 
still no luck ..

Here is some sndstat debug at verbose=2:

Your's stumped!
