I switched my NVidia GeForce GT220 video card from the Sempron computer to the Athlon II. I immediately ran into a "no sound" problem in both Win 7 and VL7 Standard RC2, which my friend google showed me how to fix. I had to go into BIOS and change Onboard Sound from "Auto" to "Enable." That immediately fixed the sound problem in Windows and VL7.
The problem was that the video card includes the possibility of connecting with HDMI and unless the computer is forced to use the onboard sound (ATI IXP), it "automatically" selects the HDMI sound through the video card. I don't have any HDMI connections, so if it's using the video card's HDMI, I get no sound.
VL 7 wants to use HDMI. I selected ATI IXP in Alsamixer and in XFce's mixer, but still no sound in browsers. I do get sound if I play an audio file with VLC or Gnome MPlayer but not necessarily other media players (Exaile doesn't work, for example).
What I want to know is how to blacklist or otherwise completely disable the NVidia HDMI audio option so I can make ATI IXP audio the only option. Thanks in advance.
