[Raven/Raven2/FireFlight/Renoir AMD Ryzen] No Sound at all

[Moritz Wenzel]

After Upgrading to Ubuntu 20.10 (From 20.04) I noticed, that my Audio Output didn't work anymore.
Switching between different Kernel Versions (Mainline 5.8.16 and Ubuntu Stock 5.8.0-25, 5.4.0-52) doesn't change that. Even on a fresh 20.10 Livesystem i get the exact same problem (On 20.04 Livesystem it works)
An Output of "$ lspci -nnk | grep -A2 Audio" shows that the Output device uses the wrong Kernel Module (Audio Input is working since it uses the correct kernel module and driver)

I have the same model and same problem. Nothing to add apart from a workaround which might be useful to address the problem, I hope.

1) I manually remove the module snd_rn_pci_acp3x.

Microphone stops working.

2) I restart pulseaudio with pulseaudio -k

Sound output starts working.

3) I manually reload snd_rn_pci_acp3x

Microphone detected and working again, without affecting the 'sink' (output).

On a side note, but somehow related, the led light of the mic button (F4) is always on, whether the mic is muted or not.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Nick Price (dominotree)]

The above steps about removing snd_rn_pci_acp3x didn't work consistently for me, but one thing that *has* (albeit a pain) is to boot with snd_hda_intel blacklisted in /etc/modprobe.d/blacklist.conf and then when I'm logged in, comment out that line and load it with modprobe.

I still get weird behavior as mentioned above with the keyboard indicators, but it does seem to otherwise resolve the issue.

[Florian Beier (flobeier)]

I use this small script based on Giuseppe's findings as a workaround:

#!/bin/bash
sudo modprobe -r snd_rn_pci_acp3x
systemctl --user restart pulseaudio
sudo modprobe snd_rn_pci_acp3x

I also have the same problem now on Pop!_OS 20.04 after installing some updates. I suspect libasound2:amd64 (1.2.2-2.1ubuntu2, 1.2.2-2.1ubuntu2.1) beeing responsible, since this is the only sound related update that I installed today.

I also tried 20.10 two weeks ago and had the exact same issue there, so I went back to 20.04 ...

Could you try to install back the old version (the deb files are on https://launchpad.net/ubuntu/+source/alsa-lib/1.2.2-2.1ubuntu2/+build/19854508) and confirm if it resolves your issue?

[Hui Wang (hui.wang)]

@Thore,

Please try this libasound2 (ubuntu 20.04):

sudo add-apt-repository ppa:hui.wang/pa-testing
sudo apt install libasound2

This will install the testing version 1.2.2-2.1ubuntu2.1+testamd

[Thore (portram)]

I looked into the apt history and I actually updated the following sound related updates (these are the old version numbers that seemed to work)

- libasound2:amd64=1.2.2-2.1ubuntu2
- libasound2:i386=1.2.2-2.1ubuntu2
- libasound2-data:all=1.2.2-2.1ubuntu2
- alsa-utils:amd64=1.2.2-1ubuntu1

I could roll alsa-utils back since, this version 1.2.2-1ubuntu1 is still in the repos. That does NOT resolve the issue, I already did that before even posting here.

Then I downloaded libasound2_1.2.2-2.1ubuntu2_amd64.deb from the link you provided. I get the following message:
$ sudo dpkg -i ./libasound2_1.2.2-2.1ubuntu2_amd64.deb
[sudo] password for thore:

I don't know what's wrong, but it is not working.

Kind regards

I get this

You might want to run 'apt --fix-broken install' to correct these.

Is this the famous dependency hell everyone is talking about?

[Hui Wang (hui.wang)]

I already tested the testing package with 20.04, it worked.

And this is the testing package for 20.10, I don't know if this could fix the issue for 20.10 or maybe 20.10 needs more patches.

I built a testing package of libasound2 for 20.10, please install and test it:

sudo add-apt-repository ppa:hui.wang/pa-testing
sudo apt install libasound2

This will install the alsa-lib 1.2.3.2-1ubuntu3+testamd

reboot.

[Florian Beier (flobeier)]

@Hui Wang

I installed your package and rebooted. It seems to fix the issue, audio is working as expected again.

One thing I noticed is that when I mute the speakers or microphone via their media keys (F1 and F4) the LEDs on the keys don't light up. It may not be related to this issue though because when I activate the FnLock the LED on the Esc key also doesn't light up.

[Thore (portram)]

@Hui Wang

I installed everything and it seems work now properly as well on my T14.

[Nikola Snele (n-schnelle)]

Hi, installing older packages

sudo dpkg -i libasound2_1.2.2-2.1ubuntu2_amd64.deb libasound2-data_1.2.2-2.1ubuntu2_all.deb

fixed sound issues on my Lenovo Ideapad 5 14are05 with Ryzen 4500u.

Please release fix asap, this is a huge bug (to lose sound after update).

[Nikola Snele (n-schnelle)]

I can confirm that libasound2 from ppa:hui.wang/pa-testing works.

[Dustin Nisbet-Jones (d.nisbetjones)]

So far this libasound2 fix seems to work for me as well.

Acer Swift 3, Ryzen 4700U with Ubuntu 20.04 LTS & also recently updated to 20.10 (both versions effected).

[Ronin Hinojos (frost5n)]

This Libasound2 fix did not help me, and i still do not have hdmi audio. My laptop, and system are detecting it, and allowing me to select it, but when i select the hdmi option, there is no sound.

I am on a asus vivobook 15 with a ryzen 3 3200u mobile with vega graphics, and i am on ubuntu 20.10

[erio (eri0)]

this is broken for me after latest update in Ubuntu 20.04, on a Desktop AMD Ryzen machine.

@Hui Wang:

What can I Do?
