mixer: speaker.volume=0.00:0.00: Device not configured

New message appearing in boot.log ( dmesg -a )

mixer: speaker.volume=0.00:0.00: Device not configured
This is a fairly new message appering in boot_log for 15.1 Stable, that i did not notice previously.
No info as to which Audio device its about.

Certainly the desktop computer does not include the IBMPC era PC-speaker.
Mixer(8) manual page does not mention a configuration file.
Only suspect i can see is the "speaker" listed with the pcm5 audio ports on the Decktop PCs front panel.
which does not appear to be a physical device as Headphone Volume is the "vol" device.
any ideas ?

I'm not sure exactly what you are asking, but I have never considered a "speaker" being a "recording" device.
But pcm5 looks like a secondary connection to the front jacks on the system. pcm4 is connected to the rear panel jacks.
It's possible that an output is not physically connected on pcm5
 
I found the ALC662 datasheet

There Is ofcourse a Microphone input jack on the Front panel that is a recording device.
and the MIC device is missing from the pcm5 list above.

is the Software/PCM driver, mislabeling the MIC device as Speaker ?
