No sound is playing from this laptop

[Adrian Barbuio]

I recently installed Ubuntu 19.04 on this protab laptop. In the settings menu the sound output shows a headphone and a multichannel output option. There is no sound coming out of either system, despite there being sound detection demonstrated in the sound bars in the output menu moving with the playback audio. I have tried force restarting/reinstalling Alsa mixer and pulse audio and all the obvious things such as checking sound level settings.

the issue is probably not from the UI but from pulseaudio/alsa/kernel

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1839006

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

responding to the automated message, I ran the required code and the information retrieval screen hangs and the terminal reads:

Thus I cannot run this command

The audio on your machine is Intel ASoC audio, it is not Intel HDA audio. you need to add ucm conf files specific to this machine:

git clone git://git.alsa-project.org/alsa-lib.git
cd alsa-lib
backup all contents in the folder of /usr/share/alsa/ucm/
sudo cp -rf src/conf/ucm/bytcht-es8316* /usr/share/alsa/ucm/
reboot
#check if audio works

To restore to original state:
restore all contents in the folder of /usr/share/alsa/ucm
reboot.

[Adrian Barbuio (oiubrab)]

Hello Hui, I followed the steps you outlined, but my laptop still isn't playing sound.

[Hui Wang (hui.wang)]

Then we need to debug pulseaudio, I guess the pulseaudio meet some errors when initializing this sound card according to ucm, to do so:

edit /etc/pulse/client.conf
add a line: extra-arguments = -vvvv --log-target=file:/tmp/a.txt
reboot and upload the a.txt to lp.

[Adrian Barbuio (oiubrab)]

Adding this line to the conf file does not generate the a.txt file on startup. I tried adding the line, altering the line with the extra arguments tags and adding to the extra arguments variable

[Hui Wang (hui.wang)]

The client_3.conf should work, put this file to /etc/pulse/client.conf
reboot
check if there is /tmp/a.txt

if there isn't, please run 'ps -aux | grep pulseaudio" to check if pulseaudio is running.

[Adrian Barbuio (oiubrab)]

Again, I have followed the instructions here. There is no a.txt file in the tmp folder. It seems like pulseaudio is running.

[Hui Wang (hui.wang)]

your output is different from mine:

gdm 1194 0.1 0.0 1153544 11656 ? Ssl 14:13 0:00 /usr/bin/pulseaudio --daemonize=no
hwang4 2205 0.5 0.0 1172556 12604 ? S<l 14:14 0:00 /usr/bin/pulseaudio --start --log-target=syslog
hwang4 2696 0.0 0.0 21532 1076 pts/0 S+ 14:14 0:00 grep --color=auto pulseaudio

[Adrian Barbuio (oiubrab)]

Yes I see. I have followed your instructions. Tried a different way. Is this it:

[Adrian Barbuio (oiubrab)]

I am able to get the pulseaudio log, but not on startup (in the tmp folder) I've tried a few methods, but nothing works.

[Hui Wang (hui.wang)]

Did you install the timidity? it can't work well with pulseaudio.

dpkg --list | grep timidity*

sudo dpkg -r timidity
sudo dpkg -r timidity-daemon

reboot

[Adrian Barbuio (oiubrab)]

No, I haven't installed timidity. It seems to be that the drivers for this laptop do not exist

[Hui Wang (hui.wang)]

But according to logs of #5 and #16, the driver works fine.
card 0: Audio [Intel HDMI/DP LPE Audio]
card 1: bytchtes8316 [bytcht-es8316]

2 card(s) available.
    index: 0
 name: <alsa_card.pci-0000_00_02.0-platform-hdmi-lpe-audio>

    index: 1
 name: <alsa_card.platform-bytcht_es8316>
 driver: <module-alsa-card.c>

I think the problem is the UCM and pulseaudio. I don't know why your pulseaudio can't generate the /tmp/a.txt
