alsa 1.2.5 upgrade errors


Executing (v 1.2.5 upgrades)

alsactl restore


yields this message:


alsa-lib parser.c:2372load_toplevel_config) Unable to find the top-level configuration file '/usr/share/alsa/ucm2/ucm.conf'.
alsa-lib main.c:1402snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2

But, sound on my system functions, nevertheless.

Harmless?

Or needs attention?

Does your microphone work? My laptop's built-in microphone stopped working when I upgraded alsa-utils to 1.2.5.

I get the same errors.

Downgrading the alsa-utils package to the previous version (but not alsa-lib and alsa-plugins packages) "solved" my problem with the microphone.

EDIT: Apparently, I am even newer to Linux audio than I already thought. My microphone now also works with the latest alsa-utils version. I had never seen or heard of the "alsactl" command before today, but "alsactl store" and "alsactl restore" seem to have solved my problem (despite the errors).

Latest alsa 1.2.5 rebuild shows this. Seems that github patches not yet applied for SW?

alsa-lib parser.c:242error_node) UCM is not supported for this HDA model (HDA Intel PCH at 0x6041118000 irq 183)

Same error here on latest alsa-lib-1.2.5 from today's changelog. I even downloaded the source and recompiled with USUARIONUEVO's patches and it still has this error. Hopefully it will be fixed upstream soon.

Hopefully it's already been fixed. It's part of tonight's system update.

That's what I am talking about, I already upgraded to tonight's changelog. That didn't fix it, so I downloaded the SlackBuild source from tonights update and recompiled it with the above patches and I am still getting the error. However everything seems to be working fine other than that message during boot.

The -3 version from today fixed it for me.

-3 did not fix the missing mic for me. Moving back to 1.2.4 did...

Same here, todays -3 did not fix it for me. Everything works correctly, I just get that above error when I run "alsactl restore". removing it from my rc.local gets the error to go away but then my sound starts muted on each reboot. Not a big deal, hopefully this will get fully sorted about soon. For me this is more of an annoyance than a real problem.

More precisely, I had no sound (without downgrading) until -3 so it was a more than an annoyance in my case.
