Comprehensive Sound Problem Solutions Guide

I can get sound playing just fine, but I can't seem to get recording working. When I go to the System>Preferences>Sound and test the record setting it always outputs and error with

"Failed to construct test pipeline for 'gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat'"

Any idea what causes this, or how to fix it?

I have the exact same problem with my AC97 card in Gutsy at the moment.

My onboard card is also an AC'97 I believe. Sadly, my searches of the forums, and google itself has not yet provided any work arounds. =/ Hopefully someone can figure this one out.

I have the same problem with my soundblaster audigy in Gutsy, it worked fine in Feisty.

Do you fellows suppose it's worth starting up a new thread for the

"Failed to construct test pipeline for 'gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat'"

problem? I have browsed various sites for the past week and can find no fix.

Finally got this damn thing to work.

I have a intel8x0 chipset and 2.6.20-16-generic kernel.

I followed the HOWTO but hit a snag. I had to compile the driver myself. At step 6, I first chose "If you chose module-assistant" option but it failed to compile properly. The log shows the compile croaking at linux/config.h As some might know, linux/config.h was removed starting 2.6.19 kernel.

So I had to follow the "Using drivers from alsa-project" option and I used the 1.0.15 final release which is recommened because, well it is final Also, older versions may not reflect the removal of linux/config.h Compile succeeded but modprobe refused to work complaining about undefined symbols. Nothing a restart could not take care of. Now it all works

Thank you !

Hmmm....followed the guide, and it says I have sound. All lights green, no mute, whole 11 yards. No sound. I know the speakers are not plugged into the wrong port, as they are built into the laptop.Headphones don't help either. Any help on this?

Have an ATi SB450 HDA Audio chip in this laptop.

EDIT: Except WINE gives me failed audio tests...curious...

Hello all

I followed the guide and ended up getting hung up compiling the drivers.
I go the module-assistant way and im stuck at the part where you sit there and wait for the bar to get to 100%
it dont do that
Ive tried twice and both times i get to about 50 % and then an error message pops up
It says something about process not being able to continue or something
But i believe my problem actually is for another reason.

I have Feisty installed on an Everex XT5000T
Everything but sound is working.
The sound device listed for it is a Realtek ALC885
But when i enter the command: lspci
It says my audio device is of Nvidia make.

Am i correct in guessing there is no support for Realtek thru ALSA because they dont list Realtek as a vendor on their list.

Help please. Im getting sick of fiddling with commands that do nothing

Audigy no sound problem SOLVED


1. Open the volume control app
2. Edit -> Preferences
3. Check "Surround" and "Audigy Analog/Digital Output Jack"
4. Increase the volume for the Surround channel.
5. Go to the Switches tab and untick the "Audigy Analog/Digital Output Jack" box.
6. Wonder why the hell Ubuntu sound architecture is so useless.
7. The end.
