Yes they are. See the block diagram in Quartet user's guide. Subdevice hw:x,0 corresponds to channels 1,2 while hw:x,1 corresponds to channels 3,4 and SPDIF input/output. That is 4 channels in total.

I seem to have more problems. The capture devices in hw:x,0 work, but hw:x,1 doesn't. Testing hw:x,1 with arecord gives "File descriptor in bad state" and using the multi pcm device gives "Input/output error". Multi pcm works if I combine just the first two channels of each device to form a four channel device.

I wonder if there is anything particular in alsamixer that needs to be switched to make the 3/4 inputs work?

Alsa is 1.0.24 on XBMCbuntu, I will look in to upgrading to 1.0.25.

Confirmed, there is a bug somewhere in the quartet driver. Since I made the quartet support in the ice1724 module, I will take a look at it and fix it. I am afraid it will take a few days though. Thanks for detecting the bug and for your patience too

That's very nice of you! And thanks for confirming it as a driver issue. In the meantime I can continue setting up the base 2-channel system. Surround channels and subs can be set up later for practical reasons too (new apartment, undecided placement).

Default sound card config

I recently added a sub to my desktop setup and cant figure out how to do the sound card config. Sound card is m-audio revolution 7.1. I will be running it in 2.1 mode. OS is kubuntu 12.04.

I have setup the card as 7.1. The only options in the Settings->multimedia->phonon settings are stereo, 5.1 and 7.1. The sub is not working under this setup.

I tried OSS also, using the command line test programs, the sub works, but most of the music players dont seem to work with it. The full range signal goes to speakers and I would like to send it to sub only at times.

I want to configure the following features:

1. crossover at 80 or 100hz.
2. Ability to send the bass signal to just the speaker, just the sub, both.

Any pointers on how do i do this? I didnt go through this thread in totality but searched and couldnt find the relevant info.

I had some issues with my simple sound setup at work with Ubuntu 12.04 that went away with mint 13.
Since mint also uses pulse audio by default, it may not be optimal but you can try it by booting from a Live CD. You might also want to try Lubuntu, which uses Alsa by default vs Pulse audio. Check this page for some interesting info https://sites.google.com/site/comput...inux-for-audio I've run into sound issues with Ubuntu a few times and sometimes the path of least resistance is ripping it out and starting from scratch.

Try Linux Mint it's idiot proof. Download the MATE version and install alongside windows (you can then choose which OS to use at start up.

Main Page - Linux Mint

If you don't like it - windows control panel - add/remove programs - LinuxMint - remove

Mint is the biggest linux distro nowadays I think and it's the same functionality as windows (but faster and more reliable etc). (I've used it hassle free for 5 years and I'm a full weight idiot so that's saying something about how versatile it is).

There are plenty of reviews etc on youtube. For those of you yet to try Linux look at this (and even this is how good it was "back then"):

I love Linux mint !!
I use the KDE version and there is very little that I have found that I have to go back to windows for.
I can even run Circuit maker in it and that is a big plus for me.

I have Ubuntu studio as well, But its installer is a PITA when you want to do a multi-boot system.
And beware if you have windows installed and if it fails for any reason you will lose your windows boot file and you will have start all over so backup your data First before attempting to install Ubuntu.

Some may not have any issues, but this what I have been through.
I also use a set of SCSI drives as well so it gets even more confusing at times.

Linux Mint installer works every time with Windows and as well for a multi-boot system with Windows and Ubuntu installed on separate drives.

The nice thing about Ubuntu Studio is the apps that come already as part of the package.
But all of these can be installed manually via software manager into Mint.

When I first started with linux I tried Ubuntu and I couldn't get the graphic driver to work properly wit a dual monitor setup as I am using an older system with a GT7600 card.
Linux mint 12 worked the very First time I used it.
The latest version of Ubuntu seems to have solved this.

Now the only issue I have now is that in Ubuntu and Linux Mint 13 I can't set one of my monitors to 1600X1200 resolution as the monitor does not support that resolution but will display it.
I am able to do this in Linux Mint 12 and Windows as well.

I have had only one audio issue in a earlier version of Ubuntu and I think Lmms or Ardour as it was glitching out.
This appears to be fixed in the latest versions.

I have never had any problems with Mint 12 or 13 as far as audio is concerned except having to re-install VLC in Mint13 because the sound system wasn't linking up to it for some reason on the initial install using my Gina24 card.

The only time I have ever locked the system up is on occasion with Firefox using the Ant Toolbar to download videos.
This may be just a problem with the Toolbar.
With Google Chrome I have never ad any issues.
I don't use Firefox much so I don't know about any more issues there.

My onboard sound works as well as my Gina24 card,But I had to turn off the onboard sound system in the Bios in order to use the Gina card or else linux gets confused and defaults to the onboard system.
Even though the card was recognized and appeared to be installed with the stock system I could not get it to work and had to do a re-install.

Since then I had replaced the Gina24 sound card with my Creative X-FI card but I have not learned how re-install the AlSA drivers manually yet and doing a re-install is not an issue as I just haven't taken the time to do so.

I love Linux and spend 90% of my time using as it is much quicker and snappier than using windows.
Especially on my older Opty185 and P4-3's.
Not to mention that it is very stable and free of any virus issues that I have found so far.

When I installed one of my TV tuner cards it worked the First time without a hitch.
This was not the case when trying to find the right drivers and install them from ATI for windows!

In linux all I had to do was install the TV app and now I have instantly a DVR!!
How cool is that?!!!!

I am hoping to learn more about Lnux and learn the working ins and outs of it as well.
It reminds me of the joys I had using OS9 on the Radio Shack Color Computer with a Hard drive, But even better on a much much more powerful and faster machine!!

Cheers !!

Oh My God, I just had a flash back to 1982(ish), a co-worker was doing the same thing with a CoCo, OS9 and Hard drive, in his mad scientist basement..

Btw.. At work, I've got an AMD Opteron with an Nvidia Quadra running a 30 inch monitor at 2560x1600 on Mint13, and quite nicely I might add

It is very impressive how far the new Linux Distros have come in the last few years.. Lubuntu doesn't have the eye candy, but it also "just works" and runs better on older systems, since they have tweaked it for lower system resource usage.

If sound quality is important, having Pulse audio out of the way (Lubuntu leaves it out, so you dont have to mess with trying to remove it and fix the dependancies) is very important.
