I know this problem has been discussed n number of times here. I have been googling for this but could not find proper resolution. It seems that i have two problems and solving them can cause other problems as i have see earlier too. Prob 1. I am using Gateway 4535Gz laptop and in the configuration document it shows that i have Analog Devices SoundMAX Integrated Digital Audio (I have downloaded chip identification util from intel site and i can give you exact chip number for the same if you need to assist me.) but in linux when i do sound configuration from GNOME it detects that i have intel ac97. I dont know how they are related. Prob 2. If the sound card detected by linux is accurate, still i dont have sound. I have gone through each and every documentation in alsa proj site and double checked all the mixer settings that nothing is mute. If i try to install new alsa driver ( alsa-driver rpm is not installed in fedora and its not available on fedora site. Only alsa packages installed on my system are alsa-lib and alsa-devel). it screws up the module information and next time when i do modprobe snd_intel8x0, it gives me tons of errors. Please let me know if any one can help me in what is going on.
