Good morning, I've got a new system with a fresh 6.4 installation. I didn't check if the sound worked at first but I know it doesn't now. :) The system board is an ASRock Extreme6. The Specs say it has a Realtek ALC1150 audio chipset and 7.1 channels. I'm running KDE and an Nvidia X driver (I need the video performance of this driver - sorry about that). The System Tools for Audio Output list 4 devices: HDA Intel (HDA Generic) Default PulseAudio HDA NVidia (HDMI 0) The speakers are connected via the typical audio jack and when I test "HDA Intel (HDA General)" it says that the default device did not work and it is using the PulseAudio device. I tested all 4 devices and nothing ever played. I've also made sure I have the audio jack plugged into the right port on the board :) I Googled a bit and one site suggested reinstalling the alsa kernel module, which I did. No change - still no sound. Any suggestions? Thanks! Jeff _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
