Hi, I have a shiny new Dell D820 and there is no sound from kernels >= 2.6.9-42, but 2.6.9-34.0.2.ELsmp continues to work very nicely. This bug is the identical to bugzilla #202735 I've tested these kernels without success: kernel-smp-2.6.9-42.EL kernel-smp-2.6.9-42.0.2.EL kernel-smp-2.6.9-42.0.3.EL kernel-smp-2.6.9-42.23.EL (from jbaron repo) kernel-smp-2.6.9-42.22.EL.jwltest.175 lspci -v reports 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) Subsystem: Dell: Unknown device 01cc Flags: bus master, fast devsel, latency 0, IRQ 177 Memory at dfffc000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable- Capabilities: [70] Express Unknown type IRQ 0 Capabilities: [100] Virtual Channel Capabilities: [130] Unknown (5) thanks! daryl
The most common cause of a problem like this is that the controls and outputs are improperly connected. Have you tried unmuting and maximizing volume controls for both inputs and outputs? If you do so, do you get any sounds at all? What about with the speakers and/or headphones plugged-in to other jacks? Please attach the output of running 'dmesg' just after attempting to play sound for the first time after a reboot.
Hi, Thanks for the help. Lets see, I'm trying 2.6.9-42.23.ELsmp at the moment. I try running gnome-volume-control and aumix, no sound. Hmmm, the speaker is onboard, so I don't think I have any cables to connect. I tried muting and un-muting. Nothing comes to dmesg after trying sound the first time... 2.6.9-34.0.2.ELsmp continues to work.... thanks so much! Sorry I'm not much more help here.
Please try adding some lines like this to /etc/modprobe.conf: alias snd-card-0 snd-hda-intel options snd-hda-intel position_fix=1 You probably already have the first line anyway. Do not replicate it, just add the options line. Does this make things work better for you?
Hi, Thanks for the continued help. Currently, my /etc/modprobe.conf looks like: alias eth0 tg3 alias scsi_hostadapter ata_piix alias snd-card-0 snd-azx options snd-card-0 index=0 options snd-had-intel model=3stack install snd-azx /sbin/modprobe --ignore-install snd-azx && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-azx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-azx alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd alias eth1 ipw3945 Hmm, note the "snd-had-intel", I don't think I added that. So I added: options snd-hda-intel position_fix=1 to that file and fixed the "had" to 'hda'. and restarted... nothing, sorry, but thanks!
Created attachment 142992 [details] modprobe.conf Let's try this modprobe.conf instead of the one you are currently using.
Hi, thanks for the response. Sorry, still no sound. I surely hope I am not doing something stupid, but a simple reboot into the old kernel continues to work.
Hi, I've just tried 2.6.9-42.32.ELsmp from jbaron's repo and still no sound to be heard. I wish I was of more help. daryl
Greetings, I've just tried 2.6.9-42.40.ELsmp from jbaron's repo and no sound :( I reboot into kernel-smp-2.6.9-42.0.3.EL and sound works. Any ideas? thanks so much! daryl
Ooops, it is 2.6.9-34.0.2.ELsmp that continues to work.
Hi, I asked on the nahant-list and got this kind response: http://www.redhat.com/archives/nahant-list/2007-January/msg00344.html with a link to this EXCELLENT page :) http://people.redhat.com/stransky/alsa/ I built alsa-driver-1.0.13.RHEL4.tar.bz2 for 2.6.9-42.40.ELsmp and now have sound! Yipeee! I'll keep checking stock el4 kernels to see if sound comes back. Thanks! daryl
Greetings, I just gave 2.6.9-48.ELsmp (from beta channel) a spin and no sound is to be heard :( I then built alsa-driver-1.0.13.RHEL4.tar.bz2 and now have sound, so at least there is a workaround. thanks, daryl
Hi RedHat, No love with el4.5's 2.6.9-55.ELsmp built alsa-driver-1.0.13.RHEL4 again and I have sound. daryl
No love with 2.6.9-55.0.2.ELsmp , perhaps I should just bite the bullet and try RHEL5 :)
We are planning on doing an ALSA update for 4.6 which should resolve most of the sound issues.
Thanks Brian, I broke down and upgraded to RHEL5 and sound works out of the box! Yippee. daryl
