"Speech POST Reporter" [Disabled] will stop the messages.
In the Hardware Monitor BIOS page, select "CPU Fan Speed" and
set it to [Ignore]. Since the thermal monitoring will still be
enabled, you'll get a warning if the fan actually stops, and
the CPU is overheating. Asus COP should also shut down the
board, if the CPU overheats enough. Using this option will allow
the "Speech POST Reporter" to be left enabled.
As for your sound symptoms, it sounds like a DC leakage problem
with your speaker system. Everything on the sound chip is AC coupled,
which means signals entering or leaving the board, are periodic
signals centered on zero volts. Now, if the caps used in an
audio path, have a DC leakage path (i.e. a resistor in parallel
with the capacitor), this can charge up the input on another device
until it gets to the point that the sound signal runs out of dynamic
range. To test for this, get an audio Y cable, and plug a
headset into one side of the Y, and your speakers into the other
side of the Y (i.e. they are running in parallel). The 32 ohm DC
load of the headphones, should give a path for the DC leakage to
go, and give a consistent sound level. This is the only theory I
can think of, unless there is some software reason why the sound
level could be turned down continuously.
You could also connect some other device than your amplified
speakers to the Lineout, to see if the sound level is
consistent. Try the headphones, assuming they are 32ohm
impedance and are DC coupled.
The most annoying solution would be to RMA the board, but
the problem might be with your speakers, rther than the
board. That is why testing with alternate output devices will
help identify whether the motherboard or the output device(s)
are at fault.
