No audio output on Marquis C515

Problem:

Details:

The stock Fedora Core and RHEL4/CentOS 4.x kernels do not have support for the onboard Intel high definition audio.

Solution:

The onboard audio requires an updated Intel high definition audio driver (snd-hda-intel) which is included in ASL 2.6.17-1.2157_FCXasl.3 kernel or higher. This kernel is provided in the ASL Fedore Core distribution CD/DVD released in September 2006.

For Red Hat Enterprise Linux 4 and CentOS 4.x, the ASL RHEL4/CentOS 4.x Device Driver CD provides a source RPM containing updated audio drivers. Before proceeding, make sure the kernel-smp-devel package is present. To install the updated audio drivers, insert the ASL RHEL4/CentOS 4.x Device Driver CD and run the following commands:

# mkdir /mnt/tmp
# mount /dev/had /mnt/tmp
# rpm -ivh /mnt/tmp/SRPMS/alsa-driver*.src.rpm
# umount /mnt/tmp
# cd /usr/src/redhat/SPECS
# rpmbuild -bb alsa-driver.spec
# rpm -ivh ../RPMS/x86_64/alsa-driver*.rpm
# sed -i -e 's/snd-azx/snd-hda-intel/g' /etc/modprobe.conf

Reboot the system to activate the new sound drivers.
