A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1943> ====================================================================== Reported By: hazelsct Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 1943 Category: PCI - ali5451 Reproducibility: always Severity: major Priority: normal Status: new Distribution: Debian etch Kernel Version: 2.6.8 through 2.6.15-rc5 ====================================================================== Date Submitted: 03-19-2006 16:15 CET Last Modified: 06-20-2006 00:33 CEST ====================================================================== Summary: No sound since ~2.6.3 Description: Greetings, Running Debian woody/sarge/etch, the last time sound worked on my Fujitsu Lifebook P2120 was with 2.6.3 (or maybe 2.6.5, but not with 2.6.8 or anything since). Esd doesn't work, nor do system beeps, and GNOME volume control says no volume control elements are found. I can get ALSA working with 2.6.8 on all of my other machines, and with 2.6.15 on all that I have tried. alsamixer runs and shows levels which I can change, but still no sound. An identical ALSA setup worked with sarge under 2.6.3 but not 2.6.8. Tried running alsaconf again to no avail. Under 2.6.3, at least when doing hardware mute and then un-mute (Fn-F3), un-mute beeps; on newer kernels, there's no beep. Now under Debian etch (testing), even 2.6.3 no longer works properly: sounds played through esd simply repeat the first second or so over and over again. I keep upgrading the kernel (most recently to 2.6.16-rc5 in experimental) hoping that this time it will finally work, but it hasn't in that long... Debian etch has alsa 1.0.10-3, and lsmod shows the following sound modules installed: snd_ali5451 20172 1 snd_ac97_codec 82784 1 snd_ali5451 snd_ac97_bus 2048 1 snd_ac97_codec soundcore 8672 1 snd snd_page_alloc 9800 1 snd_pcm lspci shows: 0000:00:04.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link Controller Audio Device (rev 01) What other information would help to diagnose/fix this problem? Thanks, Adam ====================================================================== ---------------------------------------------------------------------- hazelsct - 06-20-06 00:29 ---------------------------------------------------------------------- Hmm... Three months with no help on this bug. Decided to try something. I believe the sound card is somehow being disabled by the udev start script. To demonstrate this, I booted using init=/bin/bash, and tested the mute/unmute function key on the laptop, which produces an audible beep on unmute. It worked just fine after running "/etc/rcS.d/S01glibc.sh start" and S02mountkernfs.sh. But when I run S03udev, at the end of the script something shuts off sound so there's no more audible beep on mute/unmute. Could it be a bad module interaction? I listed the modules installed, rebooted again with init=/bin/bash, and used modprobe to install all of the modules. The beep worked fine. Then again ran "/etc/rcS.d/S03udev start", and got the following output: Starting the hotplug events dispatcher: udevd. Synthesizing the initial hotplug events...done. Waiting for /dev to be fully populated...cs: IO port probe 0x100-0x4ff: excluding 0x200-0x207 0x220-0x22f 0x330-0x337 0x388-0x38f cs: IO port probe 0x800-0x8ff: clean. cs: IO port probe 0xc00-0xcff: clean. cs: IO port probe 0xa00-0xaff: clean. done. As it exited, again the beep on mute/unmute stopped working. Please let me know what other information you need to help diagnose the problem. -Adam Powell ---------------------------------------------------------------------- rlrevell - 06-20-06 00:33 ---------------------------------------------------------------------- "Hmm... Three months with no help on this bug." Um, maybe you could try searching between 2.6.3 and 2.6.8 to identify the change that broke it?
