I have a Sony Vaio laptop , model PCG-GRZ515G . I have installed RedHat 7.3. I can't get any sound (eg system bell, test sounds, cd audio, etc) to work. The sound card is Intel Corp.|82801CA/CAM AC'97 Audio and works fine under Windows . I've listed some diagnostic info of my system below ... Can anyone out there help me please to get some sound?
thank you in advance, claire
1) often on login I have the following error :
"sound server informational message
error while initializing the sound driver
device /dev/dsp can's be opened (no such device)
the sound server will continue, using the null output device."
2) if i try to load an audio cd , I have an error "CPU overload"
I have a sony viao pcgfx505 and I think yours has the same sound chip... from my basic knowledge, your modules look ok, but I'm not sure about all that stuff in your modules.conf file.
Your problem might be solved simply by running aumix (or aumixer or something like that) and making sure your output isn't muted.
pcg-nv170 viao here. same sound chip. Mine ONLY works if I compile support into the kernel and not as a module...no idea why. As far as alsa, I've only tried it once and the latest version at the time didn't detect the i810 as a supported device.
On the plus side it looks like your 3d is working/will work if the x config file is set, but then again it looks like your sound is working as well.
Did changing the mixer settings as suggested before help?
