From your png, it seem that you are not using the alsamixer in the
latest version of alsa-utils.
The alsamixer or amixer are unable to display EQ Peaks correctly, the EQ
Peaks is a volatile read-only kcontrol which return 20 EQ peak values
from the 10-bands stereo hardware equalizer in au8810/au8830.
The graphic equalizer in vortexcontrol use a timer callback to read and
display the EQ peaks when EQ Enable switch is on. (attached vc_eq.png)

What do you mean when you say "the equalizer sliders look odd" ?
i'll show you: see png file, notice that the first 2 peaks are stereo, and the
last 2 peaks are mono... ???
Would you post the settings of the equalizer from "/data/path/mixer" or
/etc/asound.state ?
I must also say that when restoring, i always get one warning: something with
bad value for... somethingorother
When you upgrade from ALSA 1.0.8 to ALSA 1.0.9 ,the SPDIF sample rate
control ( ALSA 1.0.8 ) has been replaced by the IEC958 control ( ALSA
1.0.9 ).
You will need to delete old setting in "/data/path/mixer" and use
alsactl to store the new setting, otherwise error will occur if you try
to use alsactrl to restore the value of emunerated spdif sample rate
control settings saved by the previous ALSA version to the au8810 in
ALSA 1.0.9 driver.
Your /etc/asound.state seem OK and the equalizer is OFF.

After eight instances of "mplayer" playing stereo music concurrently in
my 32-bits machine and start an instance of aplay.
aplay outls.wav
Playing WAVE 'outls.wav' : Signed 16 bit Little Endian, Rate 22050 Hz,
Stereo

aplay abort as there is no more SampleRateConvertors available.
There is no deadlock or hang. After the "mplayer" finish playing and
release the SRCs, I can start another instance of ALSA application to
play music.
