A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2263> ====================================================================== Reported By: NathanF Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2263 Category: PCI - via82xx Reproducibility: always Severity: major Priority: normal Status: new Distribution: Grafpup Linux Kernel Version: 2.6.17.3 ====================================================================== Date Submitted: 07-07-2006 08:06 CEST Last Modified: 07-07-2006 16:52 CEST ====================================================================== Summary: All sound plays in an endless loop Description: dmesg reports 'snd_via82xx_modem: Unknown symbol snd_verbose_printk' Playing a sound file results in the first second repeating in an endless loop until the process is killed. Some applications will not play at all, flash animations in a browser play silently. ====================================================================== ---------------------------------------------------------------------- NathanF - 07-07-06 16:31 ---------------------------------------------------------------------- Thanks you for the speedy reply, that boosts my confidence. I've attached the full txt of dmesg. To answer your other question, yes this worked under 2.6.16, also under 2.4.29 if that is relevent. I'm wondering if maybe I tried to compile in too much support trying to get a generic kernel, since you mention an IRQ problem. I will try reverting the patches you suggest. ---------------------------------------------------------------------- vsu - 07-07-06 16:52 ---------------------------------------------------------------------- The dmesg output is truncated - probably the message buffer in the kernel or the dmesg program itself was too small. You can boot with "log_buf_len=64k" option to set the kernel message buffer size to 64 KB (this should be enough, unless something floods the buffer with messages), and use "dmesg -s 65536" to make sure that dmesg reads all data in the buffer. However, that dmesg piece confirms that your system uses PIC for IRQ routing, which is exactly the mode in which that VIA IRQ problems appear in 2.6.17 (and also 2.6.16.17 - that buggy patches went there too). And there is no "VIA IRQ quirk" message for the 0000:00:11.5 PCI device (this is the builtin audio device in VIA southbridges). Please give the dmesg output from 2.6.16 for comparison - probably it contains that IRQ quirk message, which would explain why sound works on 2.6.16 and fails on 2.6.17. Lots of "Unknown symbol" messages... Probably you have a mixture of modules built from different sources in /lib/modules/`uname -r`/ directory (e.g., some from the in-kernel ALSA, some from the externally compiled version). If you intend to compile ALSA separately from the kernel, you should disable all ALSA support in the kernel configuration (enable just "Sound card support"). Or maybe this is from multiple attempts to compile and install ALSA drivers for the same kernel.
