Ubuntu
alsa-driver package

Sound mostly not working

Asked by Jonatan Männchen

After most restarts, Ubuntu only recognizes "Dummy Output".

After cleaning the pulse config, deleting the file /var/lib/alsa/asound.state and restarting, sometimes only the DisplayPort Audio or sometimes also the internal sound card is recognized. After a restart, im back to step 0.

The computer is a Tuxedo Book and is setup according to this guide: https://www.tuxedocomputers.com/en/Adjustments-after-installation.tuxedo#

At least on the website of the manufacturer I can't find newer versions of the BIOS. Since the laptop is only a few weeks old, I guess that no newer versions are available.

I've checked with the manufacturer and the BIOS is up to date.

This problem still exists. If I do the following, I can solve the problem until the next reboot:

sudo apt reinstall oem-audio-hda-daily-dkms
sudo rm -rf /var/lib/gdm3/.config/pulse
sudo rm /var/lib/alsa/asound.state
rm -rf .config/pulse
systemctl --user stop pulseaudio.socket
systemctl --user stop pulseaudio.service
pulseaudio -D

After a reboot, the problem is back.

Could add that to each startup. I'm guessing that you only really need the last 3 commands. Does that make it work?

Without the apt reinstall it does not work.

I probably have exactly the same problem with the same hardware.

The log-details above are from a state where the audio device is already malfunctioning. I will post below the missing details about the audio-device as seen when it is working correctly.

Only the analog device ALC892 stops working. The HDMI devices still work!

I could reproduce the problem and solve it temporarily!

When the notebook is connected permanently to a faucet and the battery is charged, the state of the sound device does not change. When performing a hard reboot (by pressing the start button for 5 sec.) and restarting after removing the power plug, the the state of the audio device (from none to available or from available to none) may change. I suspect the probability for this to happen increases the lesser the battery is charged.

So i suspect this might have something to do with power management.

I have tested plain Ubuntu and Budgie (18.04.3) with kernel 4.18.0-15-generic and 5.0.0.29.86 also openSUSE 15.1 with kernel 4.12.14-lp151.28.16-default

BIOS is the newest: 1.07.05RTR1

I managed to recover the audio device in openSUSE by removing the audio device and making a rescan:

echo 1 > /sys/bus/pci/devices/0000\:00\:1f:3/remove
echo 1 > /sys/bus/pci/rescan

After that, the dummy device gets replaced by the audio device and analog audio works again. It did not work on the Ubuntus.

I would gladly provide more information about this problem if anyone is interested.

Is there a way to check the power management status of the device, or even to switch the status on or off?

For some reason the device ALC892 cannot be re-scanned and activated.

Changing the state of "power/control" to "auto", deleting the device and re-scanning the pci bus seems to reactivate the device:

assuming that the device (00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)) is on 0000:00:1f.3 as shown with lspci, you could:

sudo su
echo auto > /sys/devices/0000:00/0000:00:1f.3/power/control
echo 1 > /sys/devices/0000:00/0000:00:1f.3/remove
echo 1 > /sys/bus/pci/rescan

and the device ALC892 should be there again:

aplay -l

  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I still don't really understand why this is happening. I will try to find out why the state of "control" is "on" and see if i can fix it.

Gregor

Or (easier) :

echo auto | sudo tee /sys/devices/0000:00/0000:00:1f.3/power/control
echo 1 | sudo tee /sys/devices/0000:00/0000:00:1f.3/remove
echo 1 | sudo tee /sys/bus/pci/rescan

Do these commands make the sound work OK?

Gregor Darius (gregordarius) said : 		#12

sorry, directory 0000:00 is actually pci0000:00

but yes, those commands also work.

so:

echo auto | sudo tee /sys/devices/pci0000:00/0000:00:1f.3/power/control
echo 1 | sudo tee /sys/devices/pci0000:00/0000:00:1f.3/remove
echo 1 | sudo tee /sys/bus/pci/rescan

I could write a script to activate this device every time the system boots, but the real problem is not solved. Why is the system sporadically ignoring the codec for ALC892?

If you run:

sudo touch /etc/rc.local
sudo chmod 755 /etc/rc.local
sudo vi /etc/rc.local

Add the lines that make it work then add a final line of:

exit 0

Save the new file, exit vi and reboot. If you don't like vi then use whatever text editor you prefer.

It doesn't work.

Somehow this must be too early to activate the codec. The script gets executed (i included a touch /root/test.txt to check) but the codec won't get activated. Executing the script by itself works but changing the sysfs at that moment doesn't seem to have any effect.

Apologies, the TOP line of the file should be:

#!/bin/sh -e

So the entire script will be:

#!/bin/sh -e

echo auto | sudo tee /sys/devices/pci0000:00/0000:00:1f.3/power/control
echo 1 | sudo tee /sys/devices/pci0000:00/0000:00:1f.3/remove
echo 1 | sudo tee /sys/bus/pci/rescan

exit 0

Thank you, I did exactly this. The scripts works, executed standalone or during the start up process. It just has no effect at the  moment when it is called during the start up process

Ok lets try another tack:

run:

sudo vi /usr/bin/soundfix

add the below lines:

#!/bin/bash
sleep 5
echo auto | sudo tee /sys/devices/pci0000:00/0000:00:1f.3/power/control
echo 1 | sudo tee /sys/devices/pci0000:00/0000:00:1f.3/remove
echo 1 | sudo tee /sys/bus/pci/rescan

Save the new file, close vi and then run:

sudo chmod +x /usr/bin/soundfix
sudo vi /etc/rc.local

The file needs to be the 3 lines below:

#!/bin/sh -e
/usr/bin/soundfix &
exit 0

Save the new file, close vi and reboot.

The command will run the script but wait 5 seconds before the commands run. This should allow the system to setup itself. You can play with the time to wait (I used 5 seconds as an arbitrary time amount).

Thanks a lot Gregor & actionparsnip.

The soundfix scripts seems to solve the problem perfectly. I had to increase the sleep to 15 seconds and it is working like a charm :)

Is this a problem that is caused by the hardware or is this a bug with alsa / pulseaudio etc.?

Revision history for this message
actionparsnip (andrew-woodhead666) said : 		#20

Not sure. I'm terrible with sound issues to be honest

Revision history for this message
Gregor Darius (gregordarius) said : 		#21

It is not pulseaudio's fault. As it happens with Ubuntu and openSUSE i tend to say it has nothing to do with any distribution flaws.

I think it might have something to do with ALSA and the way it discovers the audio chip on startup. I will open a bug report on ALSA's bugtracker.

Did you ever report the bug Gregor?

Revision history for this message
Gregor Darius (gregordarius) said : 		#23

Yes, i posted it here: https://bugzilla.kernel.org/show_bug.cgi?id=205045

I hope this is the right place?

I actually found out that the bug is more complicated. The solution posted here only works on some Notebooks of thjs model. In some it does not work at all. I am trying to debug the kernel to find out why. But any help from the ALSA-team would be very appreciated.

I just want to confirm this problem does exist. With this notebook model Clevo N350TW. Built in speakers + SPDIF wont be activated. Only HDMI will be activated.

Below is link to alsa information script I created under Ubuntu 20.04

http://alsa-project.org/db/?f=c5f459dfb6183f1cd98f8a0bfd649a98869f009a

It happens also randomly under Windows 10 that built in speakers + SPDIF wont be activated after reboot. But will be activated after next reboot then.

Hi,

Also would like to mention that I made a bugreport. Link below.

The situation seems to have declined. The soundfix script does no longer solve the problem for me and instead of a flaky soundcard it doesn't work almost all the time.

I'm currently on Ubuntu 19.10 using linux 5.0.0-32-generic.
