Sound stumbled
Last modified: 2007-08-11 15:33:14 UTC
If sound is played, it stumbled. For example, the welcome sound is stumbled always.
Please have a look at http://www.opensuse.org/Submit_a_bug#Reporting_a_Bug All SUSE Linux OSS bugs should go into the product SUSE LINUX 10.0 or newer, because SUSE Linux is based on the SUSE Linux OSS code base. Always choose the right product when reporting a bug
Please elaborate your machine, which driver is being used, how did you configure the sound, and which desktop system is. Show the content of /proc/asound/cards. Then, check the kernel message whether any warnings come from the sound driver. If any message related IRQ, try to boot pci=noacpi (or acpi=off) boot option.
ALSA driver is used; Sound is configured by Yast automatically; Desktop system is KDE; File /proc/asound/cards is empty (Length: 0 Bytes) There is no hardware problem. I have a dual-boot system. Windows play sound well.
If /proc/asound/cards is empty, you do NOT use ALSA driver at all. I suspect you looked at the file wrongly, though. Just run "cat /proc/asound/cards" on a terminal. Also, did you try the boot parameters above?
You are right: "cat /proc/asound/cards" shows the information: 0 [CK804 ]: NFORCE - NVidia CK804 Nvidia CK804 with ALOC850 at 0xce103000, irq 225 I tried the both parameters above but the boot process freezes. With pci=noacpi the start splash screen with the enabled hard disk symbol is shown. With the other boot parameter it shows a black screen.
Is the interrupt shared with other drivers? Check /proc/interrupts. If you're using kernel-default, try the one on ftp.suse.com/pub/people/tiwai/10.0-fixes. (Note that it may take some time to get sync to ftp server.) If this still doesn't work, try buggy_irq=0 module option for snd-intel8x0 (edit /etc/modprobe.d/sound file). You may need to reboot to restart the irq assignment. Also, check the kernel message whether this IRQ is diabled. The kernel would disable the orphan irq when no driver cares.

This sounds like very difficulty! I changed /etc/modprobe.d/sound but without success.
The module option works only after you update the kernel.
Does this bug appear in the later version of distro?
No reaction since more than 2 months, therefore closing as CANTFIX (aka WONTFIX). If you can provide the needed information, feel free to reopen the bug.
