Hello.

I installed Backbox 4.1 on Lenovo Thinkpad X200 and I can hear no sound.

I have the volume indicator in top right corner (it seems active), volume slider reacts to dedicated volume buttons on keyboard, just that there is no sound.

I also had it installed in Wmware player in another computer (as virtual machine), it didn't had sound there eider.

On the top right corner at the bottom of the menu I have "sound settings", if I click it nothing opens.

What can I try in order to debug this ? I am not sure if the hardware is detected, where should I see the sound card name ?

If you want to edit sound settings:

sudo pavucontrol

Check for drivers.


Don't ask, read : http://wiki.backbox.org
or just run sudo rm -rf /*

I tried that, the volume sliders work there but no sound comes out.
Should I see a sound card manufacture name anywhere ? Like under "Volme control > Configuration > Profile" ?

How to "check drivers" ? Under "settings > Software & Updates > Additional Drivers" ? It says "No additional drivers avaialble".

I tried with jack headphones and USB headphones, no sound.

About that volume control again ...
I see under first tab ("Playback") the sliders are disabled, and under "Output Devices" I see "Built-in Audio Digital Stereo (IEC958)", is this the card or is it some generic value (placeholder) ?

And I am not sure what to select under "Configuration":
- Analog stereo duplex
- Digital Stereo (IEC958) output
- etc..

@ZEROF I tested more, I can hear sound as it comes directly from the microphone, a microphony effect but no sound from the operating system.
And the sound settings do not open from the top right corner.
Can you look at this youtube video? Maybe you have an idea:
Thanks.

Hi,

I have found this on ThinkPad site:

http://www.thinkwiki.org/wiki/Mute_button

You will need maybe to add this PPA repository as well: http://thinkwiki.de/Ubuntu_ThinkPad_Extras_PPA

This answers comes from: http://askubuntu.com/questions/133091/thinkpad-x200t-volume-mute-button-not-recognised-to-use-as-shurtcut

And two more commands that you can try to use are Alsamixer and xfce4-mixer to see if settings are ok. But first try other ThinkPad users solution. All this probelm are fixed on x201 but x200 have more issues then any other from serie X. If you have more question ThinkPad community is good place to ask as well.

Hi adrianTNT,
to find info about your HW this 2 commands can help you:
[code]
lspci
lshw
lspci show your pci card, lshw (may be you have to install) show all your hardware, after that you can check the driver with
Code: [Select]
lsmod This is only the first step, there are a lot of things that you can do, but that's the beginning!
bye[/code]

I got it to work, but I am not sure what fixed it  ???

One problem was that the volume slider doesn't make a beeping sound when adjusting volume, I usually just tested on that when trying different settings.

I tried many commands in the live CD including what was recommended above, and then I installed it on disk and at first boot it prompted for an update (including some Ubuntu base update).

Then I started an MP3 and sound was there.

I now see that in "Pulse Audio Volume Control > Configuration" I need to select "Analog Stereo Duplex" profile in order to work.
And as an output device I now see "Built in audio analog stereo".

I didn't learn much but at least it works :)

Edit: Actually I see there aren't any system sounds, errors, etc. I will look into that now.

No, initially I tested with an installed OS :) I just tested with a live CD today.
