Just rebuild v3.15. The message in the subject appears to be at the error level. Sound plays fine. Everything seems to work as intended.

Is this reason for concern?

This comes from the commit ca460f86521ed515d17dd1314f7b95183866f681 ALSA: hda - Fix CORB reset to follow specification

I guess it's a non-standard behavior of Nvidia controller. The write to these bits are likely ignored, so it's mostly harmless.

For avoiding the confusion, we may need to paper over the changed reset procedure for such chips. Could you give the specific of your hardware, especially about this HD-audio controller chip?

thanks,

Takashi

I take it you want the vendor:device id, but since you have requested additional info I have provided some more data. Please let me know if I missed anything you require. Thank you.

Below you will find lspci. I have used the alsa-info.sh script for the rest (how convenient!):
