Dell Venue 11 Pro 7140 - No sound

English Hardware
#1

I just got this tablet w/keyboard, and installed Leap 15.1. Everything works except for the sound. I found this:

https://en.opensuse.org/SDB:Intel-HDA_sound_problems

So, I did this:

head -n 1 /proc/asound/card0/codec*

and got this:

Intel Broadwell HDMI

I then installed kernel-source in Yast after reading this:

The options for the modules are available in the kernel-source.rpm, install this if it's not already on your system.

Then I did this, except I searched for Intel Broadwell HDMI:

In the file /usr/src/KERNEL_VERSION/Documentation/sound/alsa/ALSA-Configuration.txt search for the codec, in this example again ACL883.

It’s not there. Any ideas?

Hi
Can you run the following commands (as your user);


pacmd list-sinks
aplay -l

If there is output, may need to set the default sink manually by editing /etc/pulse/daemon.conf and set the default device.

Hi
It’s likely the second one, so set that as the default sink, edit /etc/pulse/default.pa and at the end add;


set-default-sink alsa_output.platform-broadwell-audio.HiFi__hw_broadwellrt286__sink

See how that goes.

#5

In System Settings (KDE Plasma), Multimedia > Audio, Devices tab, says “Outputs - No Ouput Devices Available”. I first re-did the sound setup in Yast…

#6

OOPS! I hit return after “set-default-sink” - let me fix that . . .

#7

Ok, this time when I set up the sound in Yast, it said it was starting the sound card (or something), so I’m getting closer. But in Plasma dsetop settings, it still doesn’t see any output devices.

Edit: a “Default” entry shows in Audio and Video

#8

Oh boy, this is embarrassing . . . I added that to daemon.conf, not default.pa . . . . one more try . . . .

#9

Ok, now it only shows HDMI audio in System Settings > Multimedia > Audio Volume > Devices tab

#10

Hi
And still no joy? If you change the sink to the other device: alsa_output.pci-0000_00_03.0.hdmi-stereo

Can you check the output from;


ps -ef |grep pulseaudio
systemctl list-units |egrep "alsa|sound"
#11

It works! We have sound! Here’s what I have:

ps -ef |grep pulseaudio

Many thanks for your help!

Hi
So do you have a HDMI cable to connect to say a TV and check it switches the sound to that? Or your happy with what you have?

#13

I could try it on my TV, but I’m just happy to have sound. There are now two choices for audio, one being the speakers in the tablet. Thanks again!

#14

Hi
No worries, I have one of these devices (loaned out), but not here for me to check… I’m planning to get a dock as well, but got a USB hub/ethernet device to plug into it…

#15

It’s now about a year later, and I’m happy to report that the new Leap 15.2 installation has sound! Nothing had to be fixed. Nice!
