Hi,
I've installed CentOS 5.2 to a laptop Acer 5920 for dual boot, the audio works in Window Vista, but does not work in CentOS 5.2. Does CentOS 5.2 support following audio chip or not?
Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
Thank you.
Kind Regards,
Jim
When you say it doesn't work, are you getting an error message saying that there's no sound device?
No.
Does lspci list your soundcard? If you have a super long list and can't locate it easily, you can try (but I can't promise this will work for you, it does for me however) lspci | grep audio
Please see following lspci information for the audio, seems ok.
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) Subsystem: Acer Incorporated [ALI] Unknown device 0121 Flags: bus master, fast devsel, latency 0, IRQ 66 Memory at f0500000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied>
If I recall you're using gnome. You should (but may not) have a volume icon on your panel. Right click that icon and ensure that the mute box is not checked. If it's not checked, select "Open Volume Control" and make sure your volume is turned up. If you still do not have sound try right clicking the volume speaker icon again and selecting "Preferences". Make sure that the correct device is selected.
All checked, no problem at all.
Be aware that the volume control panel default settings may not show all the pertinent controls. In that panel you may need to edit preferences to show such things as PCM control, etc. Some of these may also be muted and/or set to very low volumes.
The Volume Control Preference is set to:
HDA Intel (Alsa mixer)
PCM
Mute is not checked, and the volumes are adjusted to maximum levels.
Thank you.
Kind Regards,
Jim
