Description of problem: Upon updating from kernel 2911 to 2911.6.5, snd-hda-intel loads but produces the error message "hda-intel: no codecs initialized". This used to work with 2911. Looking at the changelog, I see several changes related to hda-intel in 2.6.19.6; I do not know which one is causing the problem. I am using an MSI 7191 motherboard with ATI RS480 chipset with ATI SB450 express chipset. The hardware is correctly identified and the correct driver is also listed in hwconf. The output of lspci has the following lines relevant to the sound system: 00:14.2 Audio device: ATI Technologies Inc SB450 HDA Audio (rev 01) Subsystem: Micro-Star International Co., Ltd. Unknown device 7191 Flags: slow devsel, IRQ 16 Memory at fe9e8000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable- The relevant lines in my modprobe.conf: alias snd-card-0 snd-hda-intel options snd-card-0 index=0 position_fix=1 options snd-hda-intel index=0 position_fix=1 remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel With 2911, /dev/dsp exists, but with 2911.6.5, /dev/dsp does not exist. Further, there are other flakiness issues with that 2911.6.5 that are not present in any of the previous FC6 kernels such as large network latency, long time to fork() before exec(), but I well submit separate bug reports for them. Version-Release number of selected component (if applicable): kernel-2.6.19-1.2911.6.5 How reproducible: Steps to Reproduce: 1. Install kernel-2.6.19-1.2911.6.5. 2. Reboot. 3. Run "ls /dev/dsp". Actual results: /dev/dsp does not exist. Expected results: /dev/dsp should exist. Additional info: As a workaround, I have switched back to kernel 2911. I can provide any other details, as necessary. I cannot take the machine off-line for more than a few minutes at a time; so, slowly ripping apart the snd-hda-intel patches to isolate the problem is probably impossible for me.
have problems with same device (ATI SB450) after updating from 2911.6.4 to 2911.6.5; from 2911.6.4 (works correctly): ------- /proc/asound/modules -------- 0 snd_hda_intel ------- /proc/asound/pcm -------- 00-06: Si3054 Modem : Si3054 Modem : playback 1 : capture 1 00-02: ALC262 Analog : ALC262 Analog : capture 2 # it is correct pcm device 00-00: ALC262 Analog : ALC262 Analog : playback 1 : capture 2 from 2911.6.5 (dont works) ------- /proc/asound/modules -------- 0 snd_hda_intel ------- /proc/asound/pcm -------- 00-06: Si3054 Modem : Si3054 Modem : playback 1 : capture 1

Same problems persists in 2.6.20.
Should be fixed in next release. Test kernel is at http://people.redhat.com/cebbert/kernels or you can wait for release.

i`ll confirm later in the eveing but i think that its still a bug in a kernel-2.6.20-1.2932.fc6.x86_64
ok, no sound in kernel-2.6.20-1.2932.fc6.x86_64 either. /sbin/lspci 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) If You need some info don`t hesitate to ask.

FWIW, alsa 1.0.14rc3 fixes a number of audio issues with the onboard sound on an core duo mac mini for me...
Looking at the patch in the 2.6.20.4-review queue: http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=blob_plain;f=review-2.6.20/hda-intel-fix-codec-probe-with-ati-controllers.patch;hb=HEAD it changes the max codecs to 4 but only for ATI controllers -- those now work in kernel 2932/2933, which includes this patch. This is the very latest from the upstream alsa tree. I guess I should try changing the max to 4 for nvidia. It used to be 4 for all controllers but that broke the ICH models...
Actually, kernel 2.6.20-1.2933.fc6 solves this problem for me :)
Works for me too. kernel-2.6.20-1.2933.fc6.x86_64. Thank You
Sound now works for me with 2.6.20-1.2933. The Intel onboard ATI SB450 HDA audio card is detected and PCM now shows up as ALC 833 Analog. Thank you for your help.
