![]() Running aplay from SSH, produced nothing, but also didn't show any error messages, as opposed to all the other plughw:X,X combinations. This can only be done by creating an /etc/nf like this: You want to remove pulseaudio, gstreamer-pulseaudio, and anything pulseaudio related.Ģ., You need to tell ALSA that the HDMI Sound on your graphics card is your sound. Alsa support for HDMI appears to be better, or PulseAudio doesn't work for HDMI audio. I removed pulseaudio as this is an instruction on the net. There may be settings related to tearing, but this setting makes video watchable instead of unwatcable. By turning the NVidia Power Mizer to Full Performance, most of the tearing and other video quality issues are gone from videos. Installing KBunbu resulted in a more stable system, which seems easier to configure. Also, the configuration utilities for Compiz / Unity are confusing or don't seem to work. The Default Ubuntu window managers / graphics utilities, Unity and Compiz are reported to do horrible things to video playback, and are confusing the issue. After trying Unity, Gnome 3, and KDE, I settled on KDE because it seems to do the best job of editing configuration files and configuring your system from the GUI controls in System settings. If you want a true HTPC, you need Linux with a real window manager. XBMC turns your computer into a DVD player, a nice one, but still mainly a DVD player. While incredibly good looking, XBMC is not very useful beyond playing movies. XBMC lacks any of the nice features you want from an HTPC, like you tube or browsing. Set the Multimedia audio output default to HDMI 1 in the KDE Multimedia settings Setting up /etc/nf to default all apps to my HDMI out on my Video Cardħ. Set the ModeLines using the calculator link above, also editing /etc/X11/nfĦ. Turned off NVidia PowerMizer (critical) by editing /etc/X11/nf (above line added)ĥ. Installed the NVidia native drivers version 304.65 at time of writing.Ĥ. It leaves me with a working computer, that can also play video (Chrome, YouTube, Pandora, etc.)Ģ. CPU is also at 20%, meaning that the decoding is being offloaded to the GPU.ġ. Now, running Totem (Movie Player), I am seeing perfect video. Later, I made the HDMI 1 output the ALSA default, forcing all apps to use this without any configuration (see below.)įinally, I set my ModeLines using this calculator. In VLC, first I set Video to X11, and Audio to my HDMI 1 output. Shutting down PowerMizer results in watchable video. The current value can be observed by noting that the speed is at the maximum of the three speed levels available. The button reads "Adaptive", but this isn't being used, this is to set it to a different value than what is current. Option "RegistryDwords" "PerfLevelSrc=0x3322 PowerMizerDefaultAC=0x1"Īdding this option worked, PowerMizer is now set to Maximum Performance. I changed 'nf in /etc/X11/nf (make a backup first), adding the Options line, in the hopes that PowerMizer is now off across restarts of the machine: Power Mizer, turning off for ever and on restarts:
