im totally at a loss of what to do. I feel like I've installed various versions of ubuntu about 20 times

may I recommend the XBMC-Freak-Live install, it just works out of the box

If it has an ION or ION LE GPU on it, it should have a BIOS setting that allows you to choose how much main RAM gets assigned to the graphic subsystem.

If so, it will likely top out at 512MB RAM for graphics. I would set it to the highest available, IF you have 2 or 4GB RAM. If you only have 1GB RAM, that is likely a big reason for jitter problems.

My Revo 1600 runs video just fine (and it is the "slow" one)under XP playing a full stream rate BD disk (Avatar w/HD Audio). It also plays it on xbmc over the hard wired net from a Win7 PC share as a 38GB MKV file (that stutters a bit, but it is not video processing, it is feed dropout). I cannot stop watching that flic. It is just too good. :-) Anyway, I hope everyone here has their ION BIOS RAM setting tweaked right!

I have been running 9.11 for months, and I UG'd mine to 4GB RAM and a 7200 rpm HD, and I drilled all the vent holes out slightly bigger and dropped the temp 10°F! Check out my mod picks:

Recently, I have been compiling my own, and experimenting with upgrading and dist-upgrading, and continuing to run. Lots of learning. I noticed my new build using mayhem 3 HD I used to see the system details in the lower right corner when I hover over "system", similar to the weather update when hovering over the "Weather" menu item. It used to be there, so either my power mngmnt is tied to it or the new mayhem doesn't have it in/fixed yet.

Anyway, check your BIOS, ION-o-folks. My new project today is a Zotac ITX H55 MOBO ($135)http://www.zotacusa.com/zotac-h55itx-a-e...board.html with 2x4 (8GB) of 1333GHz DDR3 ($200), i5-670 CPU with HD video (32nm)($204), a 500GB 7200 rpm Seagate ($90), Raidmax case($39). It has a full length PCIe16x slot, so I can put my full sized graphics card in it if I want or need to. This is a cool board. It will even take an i7 I read in at least one place. My old machine is full sized and seven years old, but it ran Vista from beta flawless, and Windows 7 as well (Asus AN8SLIyadayada), mainly due to the $400 vid card. This tiny thing will likely beat it. So, for less than $800 so far... We'll see what we'll see...
won't we? I'll let y'all know what progresses. This MOBO has no setting like that I described to you, I just thought I would let you all know what I am doing currently.

Amazing that in the past every transistor in a computer had an ounce of steel associated with it. (more in the old mainframe days) Now there are about a million transistors for every ounce of steel. Amazing.

Welcome mate! Great to see another modder at this forum Nerd

To bad I didn't come up with that. This would make the fan run at a lower rpm also and maybe prevent the FAN from speeding up down every time.

I placed a external Fan with a modded passive cooler, but it's now completely silent.

meh never ending with me...

I have aac being sent to my receiver as PCM audio, but my center channel audio is being output from my back left speaker. this is rather annoying.
here is some info

my system is only a 5.1 system does this make a difference?

No need for posting the same question in different topic's...

But did you successfully completed the guide?

The next two files will fix the wrong channel mapping of multi-channel PCM.

sudo wget http://pastebin.com/download.php?i=f5f9654bb -O /etc/asound.conf

sudo wget http://pastebin.com/download.php?i=f2e38265 -O /usr/share/alsa/cards/HDA-Intel.conf

Also it doesn't matter if you got a 5.1 system.

yes I did sudo wget those two lines and it didn't have any errors doing so.

I figured maybe some people would be subscribed to one or the other thread and respond quicker.

@ flomaster.

Make sure you are using at least nvidia driver 256.25. Pcm was broken after 185 then fixed again in 256.25

cheers

harry, I have 256.44 driver updated via the ppa before I had a 195 driver and I only got background sound no center channel. with this new one I get center channel but its being output via my rear left speaker

Only thing i can think of doing it deleting the conf files and downloading again.

Quote:sudo rm /etc/asound.conf

Quote:sudo rm /usr/share/alsa/cards/HDA-Intel.conf

Quote:sudo wget http://pastebin.com/download.php?i=f5f9654bb -O /etc/asound.conf

Quote:sudo wget http://pastebin.com/download.php?i=f2e38265 -O /usr/share/alsa/cards/HDA-Intel.conf

Quote:sudo reboot

If you still have issues after these steps can you provide a sample of the file in question. I dont think i have a file with aac audio.

cheers
