A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2248> ====================================================================== Reported By: gwagner Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2248 Category: PCI - via82xx Reproducibility: always Severity: minor Priority: normal Status: new Distribution: Kernel Version: ====================================================================== Date Submitted: 06-30-2006 06:05 CEST Last Modified: 07-07-2006 17:32 CEST ====================================================================== Summary: Sounds stops and continue Description: Every sounds "music movies" are having little pauses, it's pausing for few miliseconds and continue. It's happen on every kind of aplication. My matherborad is an Asus-A8V-Deluxe, chipset Via VT8237, Athlon 64 3000, that should work with snd_via82xx. I have an soud blaster card too, but that work fine. ====================================================================== ---------------------------------------------------------------------- gwagner - 07-07-06 01:21 ---------------------------------------------------------------------- Yes, I already heard this history about BIOS of ASUS A8V Deluxe too. The output of "lspci -vvxxx" and bootdmesg both with and without sound blaster pci board is attached. ---------------------------------------------------------------------- vsu - 07-07-06 17:32 ---------------------------------------------------------------------- Unfortunately, the kernel version number is not visible in the dmesg output; I presume that you are using either 2.6.17 or a recent 2.6.16.x version. Also seems that you have grabbed the "lspci -vvxxx" output without the PCI sound card when the snd-via82xx module was not loaded. But I see the important difference anyway - when the PCI sound card is present, the PCI_INTERRUPT_LINE register of the builtin audio device is not set properly, which is important for VIA southbridges. For testing, you can try to set this register manually: setpci -s 00:11.5 INTERRUPT_LINE=05 (before doing this, double check the "lspci -s 00:11.5 -vv" output to make sure that Linux assigned IRQ 5 to the device). If this command fixes the sound problem, then the broken VIA IRQ quirk patches which have gone into 2.6.17 and 2.6.16.17 are the culprit. Try to revert (patch -p1 -R <file.patch) these patches: http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=a7b862f663d81858531dfccc0537bc9d8a2a4121 http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=75cf7456dd87335f574dcd53c4ae616a2ad71a11 After reverting these patches the kernel will set the PCI_INTERRUPT_LINE register for all VIA devices, and interrupt routing will work properly without that setpci command.
