    Sound/Video issues


    Hi, and before I get started laying my problems on you guys let me say this is my first spin with Linux (and loving it) so any help is HIGHLY appreciated. I have done a lot of research already, but I figure I will try to find a happy medium between giving plenty of information without boring you to death. Thanks for reading.

    Okay, so I have a couple of problems, possibly related, but I doubt it.

    Issue 1: Configuring xorg.conf
    I have an Acer 23" 120hz LCD Monitor that I use for my desktop display hooked up through a DVI from my Nvidia GTX 470, and also a 40" Sony Bravia TV connected via HDMI cable to the GTX 470's mini-HDMI port.

    I have removed the Nouveau driver and installed the Nvidia 290.xx proprietary drivers. Whenever I open up the 'Nvidia X Server Settings' and auto-detect the monitors, both show up (The TV is disabled at default.) I enable the TV output, set the mode to TwinView, both resolutions are on Auto (default 1920x1080.) The Acer has a max refresh rate of 120. The TV has a max of 60. I can set both of the refresh rates successfully, make the Acer my primary and hit apply, and everything seems fine (although I don't know if the Acer took to the 120hz RR, since I don't know how to tell.) My /etc/X11/xorg.conf file looks as follows:

    # RPM Fusion - nvidia-xorg.conf
    #
    Section "Device"
    Identifier "Videocard0"
    Driver "nvidia"

    EndSection

    I tried just adding a 'VertRefresh 120' under the Driver, but display settings won't load at boot. After reviewing some other xorg.conf's on the net I've noticed mine looks bare. I'm assuming it needs some driver/hardware specific information, which is why every time i boot I have to set the settings the way I want. Of course, I tried saving the settings to the X Configuration File, but it won't grant me access. I just edit it through terminal>sudo vi /etc/X11/xorg.conf

    Issue 2: No HDMI Sound
    If you're not sleeping yet, the second issue is trying to get the HDMI sound functioning properly. First off, aplay -l shows as follows:

    I guess what I first should ask is, to produce sound from the Nvidia card, the pulseaudio prog should be using the Gf100 output, correct? Secondly, in alsamixer the Nvidia card shows 4 SPDIF (all unmuted, all on 00.) None of the outputs produce sound by using aplay -D plughw,x /usr/share/sounds/alsa/Front_Right.wav (also tried just hw,x and hdmi,x)

    One thing that might be noted also is that the HDMI sound is going from the GTX 470 to the TV, then from the TV out to the sound system. Also to be noted is that the setup is working in W7, and WAS working on a previous install of F16.

    yum is also up to date.

    Thanks, and let me know if you need any more information.

    The current versions of Xorg don't need the xorg.conf file - it will auto-detect your hardware as needed. However, you CAN create/update an xorg.conf file in /etc/X11 if you want, which is sometimes needed for weird hardware or configurations. When you installed the nVidia driver, it also installed /usr/bin/nvidia-xconfig, which if run will interrogate your hardware and create/update your /etc/X11/xorg.conf file for you. Try that first.

    As for the HDMI sound cruft, there have been a number of postings on that here in the forums recently. I don't have HDMI hardware, so I don't know enough to be more helpful with the HDMI sound at this point. My suggestion would be to do a search in the forums. As Google asks - are you feeling lucky?
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
