Sorry for the slow reply. So the snd-hda-intel module is loaded for the sound component on your new graphics card, and the snd-intel8x0 module is loaded for the onboard soundcard. What do you get when typing alsamixer on the command line. Just typing alsamixer should give you the default card "card0", but I've seen that you may have to type alsamixer -c0 to get the default mixer settings. If your cat /proc/asound/cards shows card0 as the onboard soundcard (snd-intel8x0), then either just typing alsamixer, or alsamixer -c0 will bring up the mixer settings for the onboard soundcard. Typing alsamixer -c1 should bring up the settings for the sound component on the graphics card (snd-hda-intel). From what I saw on the pastebin file that you posted previously, the snd-hda-intel module was loaded, but according to to the amixer output only for digital audio output from the graphics card, and that was set to "off". I also don't know which desktop you are using. I use KDE, and have had problems with the volume control in the panel. This control has options for which soundcard you want to use it for. On KDE you can right click on the loudspeaker icon in the panel, and select the soundcard that you want this control to use as master volume. Just a thought on that one. Personally, as you've only had these problems since installing the new graphics card, the first thing I'd do is remove the new graphics card, and see if you can get your ac97 onboard sounds working again. I don't know if you tried blacklisting snd-hda-intel, or setting the line in /etc/modprobe.conf as below install snd-hda-intel /bin/true It's worth a try if the card is still installed. I'm sort of running out of suggestions. Perhaps someone else may offer some help. Sorry for not being able to offer more positive help.
