Ok. We're trying (really hard) to port from Windows to Linux (Ubuntu to be exact)

Problem is... I just doesn't work as good as a Windows Box... The box is to function as a media centre and all reviews seen, just does not match up (unless those guys never used Windows ever)

The box consists of:-

  1. Intel Dual Core LGA 775 3.2Ghz Proc
  2. Kingston 4GB DDR-3 Memory
  3. Seagate 1TB SATA-2 HDD
  4. ASUSTeK Computer Inc. P5KPL-VM Motherboard
  5. nVidia Corporation GT216 [GeForce GT 220]

OS : Ubuntu 10.10 x64 Desktop

The propriety driver for the GT220 was installed. Ubuntu Restricted Media Formats were installed.

Software in Question:-

  1. MythTV and
  2. Movie Player

Problems is:

  1. Video is choppy... er .. horizontal "lines" can be seen within the parts of the screen that has the most movement.
  2. Only Stereo Sound can be obtained from a 5.1 Surround Setup
  3. Three weeks later... and I'm tired with this setup... therefore this posting is my final attempt prior to moving back to Windows

pavucontrol only provides "Analogue Stereo Ouput" as an option on the "Internal Audio" device, which is the only functional option.

speaker-test -c 6 -Dplug:surround51 -t wav provides only the "lady's voice" on the Front Left and Front Right Speakers.

What bugs me the most, is that one just cannot find any proper solution to the sound issue. In addition, would someone be as kind as clearing the usage / dependency / requirements of "ALSA" and "PULSEAUDIO" ? Does one still need ALSA with PULSEAUDIO ?

And for the life of me, I cannot find a working "Mixer Console" for PULSEAUDIO (Therefore the query above) ALSAMIXER nor KMIX works?

Will there be help or should I switch back to Microsoft?

Have you configured your sound card to run in 5.1 mode in the Sound Preferences control panel? You should be able to configure this from the Hardware tab:

enter image description here

By default this would probably be set to stereo, since many cards support multiple speaker configurations without a good way of telling the OS what configuration has been plugged in.

After setting the hardware profile, you can easily test it from within this control panel. With this change, you should find that stereo output is sent to both front and rear speakers in addition to supporting surround sound output.

You seem to be a little bit angry and I don't blame you. The migration from a Microsoft based system to the freedom can be a little bit irritating.

First of all, I can't give a suggestion for a really complex situation like that you are facing which seems to be a lot of work to be done and you may feel disappointed.

My suggestion for you: Give a chance to a distribution with pre-loaded software, in which you may perform several tests and find a way to learn how the things works inside of an Ubuntu system.

There are several pre-loaded systems that you can find in Distrowatch, of which I strongly suggest you the Israel Remix Team distro, in which you will find the support from the creator of this distro who is a very experienced man in which refers to Linux systems.

There are several distributions ready for multi-media (audio, graphics and video), office, programming and several other tasks.

Run a live session, from which you can check the pre-installed programs and their behavior on your system.

With the usage of these pre-installed distributions you may learn the way you did in your pre-installed Window$. Unless you started learning to make and program your windows from scratch, which I doubt a lot.

BTW: Israel Remix Team is pre-loaded with lots of software for the multi-media (audio, images and video creation/edition), programming tools, apache server, php, TV Players, Media players, and lots of useful stuff.

You may wish to check also the Ubuntu Studio distro, which is designed mostly for the multi-media purposes (audio, images and video creation/edition).
