Okay... I guess I'll just use the cloud and end my frustration with the forum limits.
Here is the sound recorded directly from the headphone jack. You can clearly hear the initial click in the audio as each sound starts playing and then about 2.5 seconds after the sound drops out, you can hear the amplifier shut off. This shutoff sound is more subtle and more audible in the right channel. There is a period following the first sample where the hiss ramps up just after the amp shuts down and just prior to the 2nd sample playing. Ignore this... the recorder was mistakenly in auto-gain mode.
Here is the link to the sound the speakers create. This was recorded with the onboard mics of the recorder. You can clearly hear the initial click in the audio as each sound starts playing and then about 2.5 seconds after the sound drops out, you can hear the amplifier shut off. If you turn the volume up, you can hear the hiss of the amplifier get cut off when it shuts down.
NOTE, these are EXACTLY the same sounds that are recorded from the headphone jack. However, the initial sound is chopped off as the audio amp takes time starting up and chops off the very start of the sound. Nice!
This should be fixable via a software / driver update. There is no reason the audio system chops off sounds and makes audible transients when going into a power save mode.
There are probably any number of users who would be glad to enable a "Never Sleep" option for the audio to get around these audible problems.
Please fix this ASUS!
If it's gating power based on the input signal the blank wave file wouldn't work.
