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.
