Running Linux on the EZBook 2?

[Anonymous]

The bytcr_rt5651 driver does not have any auto-mute control. You have to use alsamixer or pavucontrol to switch over from headphone to speaker manually.

Hi,,,, BC

Speakers do not work .

there is no way to pass your configuration?

Thanks in advance.

The asound.state I attached earlier is my ALSA configuration.

Running Linux on the EZBook 2?

@uno, try unlocking the L+R channels in pavucontrol and turn the volume of only one channel down to zero.  Does it produce any sound?

As you can see Linux audio (ALSA) is complicated. If it does not work “out of the box”, you need to go through all the details, especially the Troubleshooting section.
for example see the section “removing asound.state file“

Try run this program as root user.
[jumper@123456 ~]$

can that be the problem?

Thanks

[Brad]

@uno, when you run alsamixer is the speaker level set to zero?

did you do this from the troubleshooting guide?…
Output is muted after reboot
Run the following command:

# alsactl restore

If the problem persists, verify that the Auto-Mute option in alsamixer is set to Disabled.

In alsamixer try to increase the value of the sliders, unmuting channels if necessary.  <– and still nothing? no audio?

In that picture your speaker volume is at level zero.  If you select it and use the arrow keys can you increase the level?

@uno, do this in a terminal window..

  pulseaudio -k
  pulseaudio –start –realtime=false –log-level=4 -vvvv –log-target=newfile:/tmp/pulseaudio.log
  speaker-test -D hw:1,0 -c 2 -t wav
  pulseaudio -k

then drag-drop the file /tmp/pulseaudio.log on https://gist.github.com and post the link to it here on the forum.
also if you grep the file it should look something like this…

@uno, something else to try.  Try going back to kernel 4.11 and test that (there have been some regression bugs reported about audio on CherryTrail recently).
Also, just to check again, you did this right? –> https://github.com/plbossart/UCM/tree/master/bytcr-rt5651
What is your output of this in the terminal?…

journalctl -b -2 | grep rt5

@uno, sorry, I never used these tools before. But this is what I did to show the two sound devices on my notebook and play the test.
I get the same error if I use “hw:0” (HDMI) on my notebook and using “hw:1” (generic) succeeds…
