Neither of these worked. alsa-utils was not found. I did a search and found "sudo /sbin/alsa force-reload" which worked.

4) retest sound is surround pls

I am getting sound out of all my speakers, but the front and back speakers are still duplicated. It doesn't sound like actual surround sound.

5) report if you have no such files/folders or commands fail

only if they fail post the contents of /etc/init.d using command
ls /etc/init.d

not sure where to look for upstart but some distros keep the init.d folder for historical reasons

I just tried 13 before seeing this message. Will try the upgrade first before trying 14.

Sorry, that is what I meant. I posted my question in the linuxmint.com forums first and did not receive a response after a few days, so that was when I posted my question in the LQ forum.

sorry if offended on netacutte--- I have made a rough howto, with sexy images

Note that I had to use a modprobe config which I explain a bit ugly on page one but if you read page 2 you should catch my drift

Correct me if I'm wrong, but to extract voice from a sound file and "put" it in the central speaker one does need to use audio filters, doesn't he?
Perhaps this low-pass filter with ALSA page could be of some help...

any how I have finished my own little howto now on this page, whether its relevant, time will tell eh?

to test your speakers see if you have surround sound files in
/usr/share/sounds/alsa

I'm still around. I've been trying to figure out just how to install Pulseaudio 2. There is nothing from them or anywhere that I could find to explain how to update ones current version

We will see. Even if it doesn't help in my situation, I am sure it will be of benefit to others.

aus9 · 08-30-2012, 09:40 AM

ahh ok well if you use their packages you need to compile

http://freedesktop.org/software/pulseaudio/releases/

but you likely to have dependency hell unless you install their dependencies first

2) I assume you already have your kernel headers installed?

3) I am on debian sid and we are already on version 2.0 but ummm I would never
recommend sid to Linux newbies so have a go at compiling.

4) I suggest before you do anything you take an image of your system

I prefer a live cd and use partimage on partitions that are ext2 or 3

I don't use ext4 but I believe it is better to use something else

did you ever use Norton's ghost or Acronis or Driveimage? in windows

Too bad they don't explain this on their site. After doing some searching, I found http://www.linuxfromscratch.org/blfs...ulseaudio.html which explains how to install Pulseaudio 2 and what the dependencies are.

Quote:

Dependency hell is right. Going by the page above, I don't meet a few of the dependencies. It says I need pkg-config-0-27, but I only have pkg-config-0-26. It says I need D-Bus-1.6.4 but I only have 1.4.18. Since I am running Gnome, I will also need GTK+, but I need GTK+-2.24.11 but my libgtk2.0-0 is version 2.24.10. I haven't even looked at the optional requirements. To make things more interesting, just installing those dependencies won't work as they also have their own dependencies that I don't meet. Arrgh.

Quote:

Just what was installed when I installed LM13 which is linux-headers-3.2.0-23, though I do notice up to linux-headers-3.2.0-29 available in Synaptic.

Maybe when I get more comfortable at Linux I may look at switching to debian sid, but not today... LOL, though if I can find a distro with a gui that has a working sound setup and I can use my printer with it, I could switch,

I have used Driveimage in Windows. Linux Mint comes with Nepomuk Backup. Not sure how good it is as I get an error when I try to run it saying the Nepomuk backup service isn't running. Not really sure what that is.

I will give Partimage a look and see about using that if I decide to go with the daunting task on compiling and installing PA2.

It might just be easier to go with 414N's suggestion of trying out different audio filters.
