[SOLVED] No sound after latest alsa-lib update

geolimber · 2019-12-02 21:09:35

Hi. Never had problems with sound since arch installation about year ago (solve all after installing pulseaudio and pulse-alsa, and copy UCM of my sound card to /usr/share/alsa/ucm/).

Yesterday i update system, where i got latest version of alsa-lib. Today after switch on laptop i have no sound from speakers and headphones.

In /usr/share/alsa/ i have folder ucm and new folder ucm2 (creation date yesterday). In this new ucm2 folder i can see folder for my soundcard bytcr-rt5640.

My laptop is Lenovo Ideapad 100s-11IBY, with Intel Atom CPU Z3735F
Kernel version 5.4.1-arch1-1

Output aplay --list-pcm:

null
    Discard all samples (playback) or generate zero samples (capture)

Unmuting master with no problem.

But unmuting Speaker or Headphone:

amixer sset Speaker unmute

amixer: Unable to find simple control 'Speaker',0

When open alsamixer, by default card is Pulseaudio. When i change to my card bytcr-rt5640 i can unmute speaker or headphones manually , but can't increase sound, nothing sounds on a playback from mpv.

Other outputs:

sudo fuser -v /dev/snd/*

I was tried all solutions from archwiki with no success. But problem was solved removing /usr/share/alsa/ucm2 folder, which was recently created after latest alsa-lib upgrade. After removing this folder i'we got back the sound working as before.

That folder belongs to the new alsa-ucm-conf package, which is a requirement for alsa-lib on archlinux .
By removing it your system is no longer in the state pacman expects it to be.
This will cause all kinds of hard to solve problems.

The new package is a consequence of changes by upstream[1] and there has been an archlinux bug report[2]

I suggest you re-install alsa-ucm-conf and try to troubleshoot the issue further
Incase you prefer to stick to the older alsa version, create a package for it.

I tried to re-install alsa-ucm-conf but the problem is still there. I also tried some pkgbuilds form discussion you linked , but nothing happend. How can create a package to downgrade alsa? is there another solution?

Just tried re-install alsa-ucm-conf, this not solve problem. So for now to have some solution to make sound work i just remove folder /usr/share/alsa/ucm2 and will add alsa-ucm-conf to ignored packages in pacman.conf
Will looking for a future solution in bug report.

I tried also removing that folder, but nothing changed.
I also tried to downgrade with pacman -U to alsa-lib 1.9.1 but nothing

Important thing that i had /usr/share/alsa/ucm/bytcr-rt5640/. Did you have ucm folder with subfolder for your soundcard?
In my case initially i didn't have this folder after first alsa intstall, so i just put it manually and got sound work since that. And now had problem only when appears ucm2 folder with recent update of alsa, so removing this new folder solve problem.

I had /usr/share/alsa/ucm2/bytcr-rt5640/ . Note that the only difference is that in my case was ucm2 and not ucm

My folder content is :

First :

Alsa support is spread over several packages, all of them should be from the same upstream version.
To downgrade to a previous version, all of them need to be downgraded.

$ pacman -Qs alsa
local/alsa-firmware 1.2.1-1
    ALSA firmware package
local/alsa-lib 1.2.1.2-2
    An alternative implementation of Linux sound support
local/alsa-plugins 1.2.1-1
    Extra alsa plugins
local/alsa-topology-conf 1.2.1-1
    ALSA topology configuration files
local/alsa-ucm-conf 1.2.1.2-1
    ALSA Use Case Manager configuration (and topologies)
local/alsa-utils 1.2.1-1
    An alternative implementation of Linux sound support
local/lib32-alsa-lib 1.2.1.2-1
    An alternative implementation of Linux sound support (32 bit)
local/zita-alsa-pcmi 0.3.2-2
    The successor of clalsadrv, provides easy access to ALSA PCM devices.
$

If I wanted to downgrade alsa , I'd need to downgrade all of them except zita-alsa-pcmi .
Doing that in a clean maintainable way is a lot of work.

Second

Troubleshooting the issue so things work with latest alsa may be hard, but is very likely a one-time job.

Some questions for clarity :

Both of you have the same soundcard, bytcr-rt5640 ?

alsa-ucm-conf has these files for that card

usr/share/alsa/ucm2/bytcr-rt5640/HiFi-Components.conf
usr/share/alsa/ucm2/bytcr-rt5640/HiFi-LongName.conf
usr/share/alsa/ucm2/bytcr-rt5640/HiFi.conf
usr/share/alsa/ucm2/bytcr-rt5640/bytcr-rt5640.conf

Compare those with the files you had copied manually to get sound working .
What are the differences between your working files and the new ones ?

First thank you so much for your time.
I have those files , but I did not find a way of canceling files to get it working again. I just tried removing the entire folder (ucm2) without success. I agree with you , I want to find the solution once for all

I am facing the same problem.
My soundcard is bytcrrt5651.
For me downgrading the alsa-lib package to 1.1.9.2 solved the problem

I've looked at some of those files under the ucm2 folder and they're simple text-files .

A diff between the files for the soundcard in a working state (like those in 1.1.9 ) and latest non-working state could be very useful for alsa upstream.
Afaik alsa upstream doesn't even have one single bugreport about this, partially because most that have this issue just downgrade.
