I've got a Fedora Core 6 system (kernel 2.6.22.14) which automatically detected my soundcard just fine. The sound chip is and Intel 82801G ICH7 Family (built into motherboard) and has 8 channel audio - which worked great under windows (so I know wiring is not the issue). Since switching to Linux, I've lost the side audio channels. Now only 6 of the 8 channels work. I've run "speaker-test -Dplug:surround71 -c8 -twav" to confirm this. My modinfo of soundcore shows me: filename: /lib/modules/2.6.22.14-72.ht/kernel/sound/soundcore.ko alias: char-major-14-* license: GPL author: Alan Cox description: Core sound module srcversion: 548AA54AF08207316C104F8 depends: vermagic: 2.6.22.14-72.ht SMP mod_unload PENTIUM4 4KSTACKS I've read the WIKI, but am still stuck. How do I go about diagnosing this? Thanks, MD ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
