 |
|
This is more about better understanding my system and kernel config than an outright problem, since my sound is working.
But, like many, I don't like error messages and prefer to understand why, whether they can be fixed, and what they're telling me.
To try to provide relevant info up front, I have the following | Code: | $ dmesg

If I can safely ignore all of this so be it, but I'm curious because:
I just built the latest kernel and built in the HD audio support including Realtek, leaving in all other options as modular.
I don't really understand why (IIRC) early on in the boot it finds and loads the Realtek codec, but later on the snd_hda_intel module fails to load (again, IIRC)?
My ' $ lsmod | grep Intel' shows no reference to the sound module, whereas '$ lsmod' (omitted for brevity) shows "snd_hda_intel 0"
Any advice or help much appreciated  |
