MX19 - No Sound [SOLVED]

[NevilsStation]

Just loaded MX19 on a Lenovo ThinkPad W520 laptop.

I'm getting no sound. Anything obvious from here, please?

Did you select a sound card in MX Select Sound?

Is anything muted? (right click on the volume icon and open mixer)

Did you select a sound card in MX Select Sound?

There are only two options in MX Select Sound:

PCH: HDA-Intel-HDA Intel PCH - When I press "Test current sound card"
Clementine Shows surges below "Alsa plug-in (speaker test) Alsa playback on"
but there's no sound from the speakers.

CODEC: USB-Audio - USB Audio CODEC - Same behavior as PCH.

Is anything muted? (right click on the volume icon and open mixer)

Nothing is muted. Everything reacts as if sound is being processed -
but nothing is heard.

There are two buttons for sound on the keyboard, one for Mute On/Off
and the other for Volume - It's not muted & volume is at full on.

Note: I tried an external speaker & no joy there either.

In some cases I have seen just pushing up the slider on the volume (little speaker icon) is not sufficient.
Right click the little speaker icon to go into the mixer.
There you can also increase the volumes.

Try this:

Code: Select all

alsactl init

Code: Select all

sudo alsactl store

Everything is cranked up.

The only time I hear a sound is when I slide "Built-in Audio Analog Stereo" up toward 140% - I get a tone.

Nothing heard when I slide "PCM2901 Audio Codec Analog Stereo"

Nothing heard when I use MX Select Sound.

Try this:

Code: Select all

alsactl init

Code: Select all

sudo alsactl store

I did this.

Code: Select all

mx2@mx2:~
$ alsactl init
Found hardware: "HDA-Intel" "Conexant CX20590" "HDA:14f1506e,17aa21cf,00100003 HDA:14f12c06,17aa2122,00100000" "0x17aa" "0x21cf"
Hardware is initialized using a generic method
mx2@mx2:~
$ sudo alsactl store

What is it supposed to do, please?

I'm not seeing any impact.

Code: Select all

alsactl init #ALSA sound server initializes the sound card

Code: Select all

alsactl store #stores the state of the sound card configuration

On my Panasonic CF-31Mk3, I had to use those commands to get sound, even after selecting the card in MX Sound Select.

Code: Select all

alsamixer #brings up the gui for ALSA

I had luck getting sound by going into the mixer, selecting the sound card (F6), then F3 to get the playback settings, use the right arrow to change from the Master to the Headphones and then enter 'm' on the keyboard. Sound worked after that, until the next reboot.

This was fixed on the CF-31's by a member of Notebook Review's Panasonic forum. This is the fix he posted:

Code: Select all

Edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf

Look for these two Element Headphone and Speaker sections and modify them to that they look like this, by adding, editing or removing lines as necessary (requires root or sudo'ing of course) :

[Element Headphone]
switch = off
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

[Element Speaker]
required-any = any
switch = mute
volume = off 

Make a copy of the analog-output-speaker.conf (analog-output-speaker.conf.bak maybe) then edit the .conf file.

As I said, this works on Panasonic Toughbooks. I have no idea if it will work on your Lenovo. My X301 required no tweaks, sound worked out of the box when I installed MX-19_x64.

Did you go through the troubleshooting steps listed in section 3.6 of the manual and in the wiki? If you log out then log in as root do you get sound?

Sound appeared to be working - It played the Test in MX Sound Select.

The only change was to leave the laptop powered off overnight.

Oh, I did notice that the boot took extra long this morning, so perhaps one of the changes,
or the MX Update - caused something to take a new look?

I opened Firefox and tried to test a sound on a couple of sites - no sound.

Closed FF & tried MX Sound Select - no sound.

Rebooted - No sound in MX Select Sound (boot took longer than before, again).

Made the

Code: Select all

/usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf

changes.

Rebooted - no audio - and now MX System Sounds only shows one of two options.

AlsaMixer shows Card: HDA Intel PCM Chip: Connexant CX20590 & the volumes are all way up - as previously set.

Clementine shows no Devices.

If I right-click on Volume Control It will not allow me to change the level for Output Devices.

Thanks!
