Some more experimentation: modprobe -r snd_hda_intel modprobe snd_hda_intel Produces two messages: kernel: azx_get_response timeout Message from syslogd@compsci at Fri Feb 24 13:54:20 2006 ... compsci kernel: general protection fault: 0000 [1] SMP Issue seen by other people as well. It is just been discussed on the Linux-Kernel List. http://www.tux.org/lkml/ Created attachment 126450 [details]
log file from sound card detection tool
This is the output of the sound card detection tool.
kernel 2.6.15-1.2054_FC5
I can see rhythmbox playing my ogg files but there is no sound coming out of
the speakers nor headphones.
This is discussed in alsa bug #1843 as a regression for 2.6.16. After a long process it is fixed in the latest alsa-kernel cvs. I just made a patch from the cvs tree against 2.6.16 FC5 kernel and sound is working fine. This changes the version to 1.0.11rc3 for alsa-kernel. PS: The alsa bug talk about laptops but my problem was actually with a DELL desktop, so it works for all hda-intel problems. At least as far as hearing something! Audio is silent here too; a new Dell Precision box, ICH7 chipset, STAC92xx audio. Added reference to the ALSA bug. *** Bug 187905 has been marked as a duplicate of this bug. *** Updating summary, note this is broken in 2.6.16-1.2080_FC5 still too.

alsa patch for 2.6.16 based FC5 kernel
To fix this for FC5 stable you need to apply the alsa kernel patch from 3/22/2006 since this is 2.6.16 based. I am attaching what I have been using on 2.6.16-1.2080_FC5 recompiled with 2.6.16.4. The 2.6.17 based kernels would have this or a later version in already. *** Bug 189738 has been marked as a duplicate of this bug. *** *** Bug 190295 has been marked as a duplicate of this bug. *** FYI, it seems that FC4 with recently updated 2.6.16 kernels suffers from this bug as well. So I hope for official fix to be released for FC4 as well. Anything new on this one? I think this should be quite high priority for Redhat hackers as Dell officially supports RHEL and current kernel/alsa still doen't work on new Dells. Works for me on kernel 2.6.17-1.2139_FC5smp Ditto here since Alsa is updated to rc4 for 2.6.17. I am closing this bug. Well, not so good for a dell D820. I'm running 2.6.17-1.2139_FC5smp. I get the following from dmegs: --BEGIN-- snd_pcm: disagrees about version of symbol snd_timer_notify snd_pcm: Unknown symbol snd_timer_notify snd_pcm: disagrees about version of symbol snd_timer_interrupt snd_pcm: Unknown symbol snd_timer_interrupt snd_pcm: Unknown symbol snd_verbose_printk snd_pcm: disagrees about version of symbol snd_timer_new snd_pcm: Unknown symbol snd_timer_new snd_hda_codec: Unknown symbol snd_pcm_hw_constraint_list snd_hda_codec: Unknown symbol snd_pcm_hw_constraint_step snd_hda_codec: Unknown symbol snd_pcm_format_width snd_hda_intel: Unknown symbol snd_pcm_new snd_hda_intel: Unknown symbol snd_pcm_limit_hw_rates snd_hda_intel: Unknown symbol snd_pcm_lib_preallocate_pages_for_all snd_hda_intel: Unknown symbol snd_hda_bus_new snd_hda_intel: Unknown symbol snd_hda_build_pcms snd_hda_intel: Unknown symbol snd_hda_codec_new snd_hda_intel: Unknown symbol snd_hda_queue_unsol_event snd_hda_intel: Unknown symbol snd_pcm_lib_malloc_pages snd_hda_intel: Unknown symbol snd_pcm_lib_ioctl snd_hda_intel: Unknown symbol snd_pcm_lib_free_pages snd_hda_intel: Unknown symbol snd_hda_calc_stream_format snd_hda_intel: Unknown symbol snd_pcm_set_ops snd_hda_intel: Unknown symbol snd_hda_suspend snd_hda_intel: Unknown symbol snd_pcm_suspend_all snd_hda_intel: Unknown symbol snd_hda_resume snd_hda_intel: Unknown symbol snd_pcm_hw_constraint_integer snd_hda_intel: Unknown symbol snd_hda_build_controls snd_hda_intel: Unknown symbol snd_pcm_period_elapsed --END-- [bpm]$ sudo rpm -V kernel-smp-2.6.17-1.2139_FC5 [bpm]$ so the kernel is OK.
