From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: After upgrading from fc2->fc3 with the cd-set on dual Athlon smp-machines (Tyan Thunder K7 1800+ and Thunder K7X 2600+) I find that the /dev/dsp and /dev/mixer devices are missing. These can be produced by running "/sbin/MAKEDEV sound" but even with that no audible sound. On other (single Intel P-III and P-IV processors with Kernel#2.6.9-1.681_FC3) machines these devices are present and sound works as it supposed to do. All software is updated to the last version by apt-get. No other sound-cards or TV-capture-cards other than Creative Audigy LS cards are present. Yes, every slider is unmuted. Yes I have given the answer "Yes, I have heared the sound" after the system-config-souncard soundcheck (even when I heared nothing). Reinstalling kernel-module-alsa/alsaconf/udev/hal etc does not change this silence. Version-Release number of selected component (if applicable): Kernel-smp#2.6.9-1.681_FC3 How reproducible: Always Steps to Reproduce: 1. Upgrade from FC2 to FC3 with the cd-set (not yum or apt-get) 2. Bring software up to date 3. Reconfigue soundcard with alsaconf / system-config-soundcard Actual Results: No sound. Expected Results: Hear sound. Additional info: Upgrading from FC2 to FC3 should be possible and result in a working system. I do not wont to go back to the dark ages of Linux when having to start from scratch with every new release. Issues with xorg on MatroxG550, no logging and no rebooting due to selinux, getting RealPlayer to work, and finnaly this sound issue on SMP-machines have cost me a full week so far. Thats enough.
The recent updates of udev/hal etc had me wondering if perhaps reinstalling kernel-smp-2.6.9-1.681_FC3 after these updates would produce the missing devices (/dev/dsp & /dev/mixer). So I first booted in to the original 2.6.9-1.667 FC3-kernel (only to see that the devices are missing there aswell) and reinstalled 2.6.9-1.681_FC3 and the kernel-modules and alsa. Synaptic produced a message after reinstalling kernel-smp-2.6.9-1.681_FC3 : "kernel-smp-2.6.9-1.681_FC3 WARNING: /lib/modules/2.6.9-1.681_FC3smp/updates/sound/isa/wavefront/snd-wavefront.ko needs unknown symbol sys_open" Perhaps there is something with modutils was my next thought and switched from modutils to mod-init-tools, and : Bingo, that produced the /dev/dsp and /dev/mixer devices
