View Full Version : HELP! Cirrus Logic Sound Problems in FC2

5th July 2004, 09:05 AM
I have been working on my friend's computer for several nights now, to no avail. He has a Hercules Game Theater XP, based on the CS46xx chipset. It took me awhile to get this working back with FC1, but It finally did. Now with FC2 I have tried to recompiled the kernel three times trying different variations with no success.

the output of rpm -qa | grep alsa:

I have tried both compiling in support for alsa and the respective driver, and compiling it as modules. I have turned up the volume in alsamixer so many times, this is driving me nuts. I have loaded the appropriate modules with modprobe.

Perhaps there is something wrong with the driver in kernel 2.6.6 and 2.6.7 because when i started using the 2.6 series is when the problems began.

Thanks for any help in advance

yeah... so far absolutely no help, but with some research i managed to find out that alsa version 1.04 has a problem with this particular driver, the mixers for the digital outputs are not shown in alsamixer, i am waiting for the new kernel (2.6.8) to be released, which will hopefully have alsa 1.05, which will hopefully have the problem fixed

ok that fixed it,
I patched kernel-2.6.7 with the latest Alsa kernel patch (v1.05) recompiled; and the the volume controls that were missing in alsamixer have now reappeared; i haven't actually tested the stereo system yet, i will report back if they do

Indeed the sound does work beautifully through digital output now
thanks for all your help... (yep...)
hopefully this conversation with myself will help someone solve their problems

hey pico.....i am happy to see you can answer your own threads.....and dude about the icon stealing stuff.....i am stil LOL....( i just hope they dont still mine now) :mad:

its really frustrating... that icon was taken from a website that made icons originally, but i have customized it enough so now it is mine

i did some various checks to see if they were *exactly* the same thing

that shows me that every byte in the entire file is in the exact same spot... hmmmmmmm... i wonder

i opened both files with vi to look at the metadata imprinted by gimp
they were both the same

cyborg submitted the icon under the exact same name that i had originally redhat-icon50.gif
