Following up to myself, I have ruled out a hardware problem by booting the Fedora 7 Live CD and confirming that he card works under that distro. I used the F7 /etc/modprobe.conf as a cheat sheet but still am not getting audio under CentOS 5. I listed the loaded modules after rebooting and found that the sound drivers still had not loaded in spite of the modified modprobe.conf:
alias scsi_hostadapter sata_nv alias eth0 forcedeth alias snd-card-0 snd-hda-intel options snd-card-0 index=0 options snd-hda-intel index=0
I ran modprobe snd-card-0 and all of the expected modules loaded as they did under F7 but still no audio output.
I checked to be sure kudzu was seeing the device and it is: # kudzu -p ........ class: AUDIO bus: PCI detached: 0 desc: "nVidia Corporation MCP61 High Definition Audio" vendorId: 10de deviceId: 03f0 subVendorId: 103c subDeviceId: 2a5c pciType: 1 pcidom: 0 pcibus: 0 pcidev: 5 pcifn: 0 '''''''''
I want to stay on CentOS for stability and longevity reasons.
Could the Fedora 7 live cd have a newer/different driver than CentOS? AFAIR CentOS is more in line with Core 6, and Core 7 might have a newer driver by 6 to 9 months. Maybe running modinfo under each one and look at the output.
