My questions are as follows (three separate ones).
(1) From a practical perspective, what do the above codec errors mean (both for the driver
and system wide)? In other words what, exactly, is being disabled? Is some functionality
missing elsewhere because of this? Performance ramifications?
(2) I suspect that this is why, on boot, "Starting Udev...." takes longer (codec probe timeouts).
(3) What does enable_msi=[0|1] do? What does that mean? When is it necessary?
Thank you in advance all. I just need to understand this better because it just feels
like editing asound.conf may be a quickie hack and there is a more proper way to do this, that
does not result in these errors or udev delays.
