Extigy only one sound channel

[digitig]

I'm pretty much a persistent Linux newbie -- I keep trying it, getting frustrated at not getting things to work, and giving up before I get any good with the OS. Let's see if I can do better this time.

I have a Soundblaster Extigy sound card, which works fine under MS Windows. Under Kubuntu I only get the left channel -- nothing at all on the right channel. Has anybody got any ideas how I can get both channels working? Somebody mentioned that it might be to do with the card autodetecting whether one of the lines is input or output, and getting it wrong, but I don't know how to check that or fix it.

Thanks in advance.

All of that stuff seems to be about no sound. My sound card is being recognised and I have sound -- just on one channel -- so it doesn't seem to be relevant.

[dibl]

Is that a USB sound card? If so, in a terminal run

lsusb -v

and find the section where the information about that card is listed. It will begin with a line that includes the name of the card, something like this one:

Bus 010 Device 003: ID 046d:08d7 Logitech, Inc. QuickCam Communicate STX
Couldn't open device, some information will be missing
Device Descriptor:
  bLength                18
.
.
.

Copy and paste in here the first dozen or so lines of that output.

I assume you reviewed the information here: http://exaudio.sourceforge.net/

It's not encouraging that they don't list a kernel 3.x driver. Here's driver downoad site: http://sourceforge.net/projects/exaudio/

I found that, but I don't even know what kernel I have and I didn't understand the installation instructions.

Because I have sound I assume I have a working driver and it's just a matter of configuration.

[dibl]

I don't even know what kernel I have and I didn't understand the installation instructions.

You can always check that with

uname -r

Because I have sound I assume I have a working driver and it's just a matter of configuration.

That may or may not be a valid assumption. I googled "extigy 041e:3000 linux driver" and it appears the snd-usb-audio driver is supposed to work for that card. I ended up at this page: http://www.alsa-project.org/main/ind...dule-usb-audio

A very handy package for this kind of question is hwinfo, and it is available in the universe repo. So, in your terminal

sudo apt-get update && sudo apt-get install hwinfo

Then you can run the package in the same terminal with

sudo hwinfo

It will output a long list of information about your hardware, and for those items that use a driver and kernel module, it shows them. So scan down the list to the USB devices, and scan down those until you find the Extigy card, and look down the list of information under it. Does it show a driver? Does it also show a "Driver Module"? What are they? Does it show the configuration parameters being used? If you can paste in that section, it might let us guesstimate what needs to be changed.

[digitig]

I've got another problem at the moment, so there will be a delay in responding to this one. I'm not ignoring you!

[digitig]

You can always check that with

uname -r

Ok. It's 3.0.0-17-generic.

sudo hwinfo

I don't see any driver or driver module. Is that the sort of thing ALSA will be doing?

[dibl]

I'm away from home and my Linux system at this moment, but here is where I think we're headed:

- does your system have an onboard audio chip -- an intel-hda, perhaps? If it does, you will see it in the output of "lspci -v" in a terminal

- if there is an onboard audio chip, does your BIOS have an option to disable it? If so, that would be on the "to do" list

- if you can't disable the onboard audio, then we'll probably need to blacklist the module that drives it

- then we'll need to look at the files in /etc/modprobe.d/ and see if there is one named "alsa-base". If so, it probably needs an edit to set the snd-usb-audio module as the default

More later. If you want to look up Ubuntu's audio troubleshooting guidance in the links above, you will find information about these configuration issues -- even though they are talking about "no sound", the approach for "half sound" is similar.

[dibl]

OK let's see all the sound cards your system sees:

aplay -l

Let's see all the sound kernel modules that are presently loaded:

lsmod | grep snd_

Let's see what /etc/modprobe.d/alsa-base.conf has for sound configuration:

cat /etc/modprobe.d/alsa-base.conf

Let's see what the existing blacklist looks like:

cat /etc/modprobe.d/blacklist.conf

Also, I have no problem running my onboard Intel HDA in parallel with a USB webcam which has a mic, using pulseaudio, so for now let's install the needed pulseaudio packages if they're not on your system:

sudo apt-get update && sudo apt-get install paman pavucontrol phonon pulseaudio

Probably some or all of these are already installed -- no problem.

[digitig]

Ok, I upgraded to kubuntu 12.04, and XWindows stopped working, so I went hiking in the Rockies. I'm back now, I've fixed the X problem, and the sound symptoms have changed a bit. Now it sometimes gives me stereo when I boot, sometimes doesn't. I thought it was strictly alternating, toggling on each reboot, but then it worked twice in succession and it's just failed twice in succession. My answers below are from a reboot that only gave me mono. Oh, I also disabled the on-board soundcard using the BIOS.

OK let's see all the sound cards your system sees:

aplay -l

It certainly made some changes. I'll try rebooting and let you know if anything has changed.

Hi,
Facing a similar problem with the same hardware, I wake up this thread with the hope to finally find a solution.
In my case, I only have the front right and front left speakers working.
Even stranger: I have a DVD player sending S/PDIF signal to the extigy via a coaxial cable. When the computer is off, the sound-card works fine and the sound comes out from all the speakers (5.1). As soon as I switch on the computer, there is no more sound from the 2 rear speakers and the center speaker.
I've created a topic on the ubuntu forum with all the details I can get about this issue but didn't get any help so far.
Digitig, did you find a solution or a workaround for this problem?

[digitig]

No, I didn't find a solution to the problem. The computer died, and I'm not using the Extigy with the replacement computer.

Hi, I have similar problem. The analog stereo output works fine, but when I switch output to analog 5.0 or 5.1, the sound is scratchy, but still only stereo and the stereo configuration is not recognized. It means, when I click test button for each speaker, the sound is playing on both front speakers. Also, the sound seems to be a little slower (seems like some 44/48 kHz issue).

The card was recognized and enabled just after I connected it. It seems to be some driver configuration issue, because I use Extigy as external DD decoder from TV to 5.1 speakers and the 5.1 sound is good.
