One of the issues we have with the MP45-BDR (which otherwise is an awesome little HTPC for the living room) is that the blue LED on the front is VERY BRIGHT. It also blinks when the little one goes to sleep, almost as if a pulsar is approaching.
I looked into tweaking the voltage to the LED but the risk/reward pay-off wasn't there.
Instead I have opted for a small piece of transparent plastic which I shaded in with a Sharpie.
BUT Somehow we filled up the 2x1TB drives on the HTPC, so the question becomes, is the Next Project a NAS or is it a new media PC (Sandy Bridge?) to replace the one at Lorne? In particular, I am intrigued by the promise of WiDi 2.0, which might solve the problem of the bad connection infrastructure at Lorne.
SOLUTION? In the end I went with upgrading the HTPC HDDs to 2x2TB HDDs. I used WD Caviar Greens (combination of low power consumption and "brand name" reliability) so now we have 4TB of storage capacity (plus the old 1TB drives can be used in the Next Project).
Switching over the drives was fairly standard but, partly for fun, I installed a new USB3.0 card, and then used a cheap HDD dock to transfer the files (max speed observed was about 49MB/s - not earth-shattering but much faster than the USB2.0 speeds I was looking at, plus now I can use USB3.0 devices).
Now to copy those archived files onto the new HDDs and fill them up too.
% sudo sysv-rc-conf (page down until you find "pulseaudio" then uncheck all the boxes, save and exit)
Configure ALSA to use your sound card:
% asoundconf list Names of available sound cards: [card name] % asoundconf set-default-card [card name]
And ensure that libao.conf is using ALSA:
% sudo nano /etc/liabo.conf default_driver=alsa
Step 2 - Install nVidia & ALSA Drivers First, kill the GUI (you can restart it using gdm):
% sudo /etc/init.d/gdm stop
Uninstall the proprietary drivers if you installed them (Ubuntu will probably recommend you get proprietary driver version 173 or 177 when you first install).
% sudo apt-get remove nvidia-glx
Now download the latest nVidia drivers from here (I'm using Linux IA32 version 177.82) and install:
% sudo sh [NVIDIA-Linux-x86-177.82.pkg1.run] (Follow the prompts... Yes, Agree, OK, Next, Yes)
Reboot the computer and download the latest ALSA drivers from here (I'm using "alsa-driver-1.0.18a.tar.bz2"). You'll then need to decompress the file, go to the directory it creates and install:
% bunzip2 -c [alsa-driver-1.0.18a.tar.bz2] % cd [~/directory name] % ./configure % make % sudo make install
Reboot the computer again, then see what you have:
% aplay -l
Hopefully you have a device with "HDMI" in it. If not, try looking here.
Now navigate to System->Preferences->Sound and turn everything from "auto-detect" to the HDMI device (and disable ESD if it is enabled).
Open up the volume control (double click on the speaker icon or gnome-volume-control) and change "Device" to the HDMI device.
Then select "Preferences" and check anything with "IEC958" in it (also, in "Playback" make sure the IEC958 device is not muted!)
