This does sound like a likely candidate - I'm not sure if I'm up to rebuilding a kernel, particularly on a laptop, however all my other desktops are x86_64 and I'm not sure if that creates more issues for doing a kernel rpm rebuild or not?On 20/07/10 03:08, Rob Kampen wrote:Still no joy - I am at a loss to know what to check - if I boot a 194 kernel no sound, 164 kernel is fine - why the regression? Same configs, same modules loaded but now no sound - what can I check to determine problem and find a solution? no errors in logs or dmesgI would suggest you start checking back through the changelogs between kernel-2.6.18-194.el5 and kernel-2.6.18-164.el5, find likely candidates that may have caused your issue and then rebuild a testing kernel with that patch reverted. If that testing kernel fixes your issue then you've identified the issue and can file a bug report upstream. To start you on your way, this patch looks like a likely candidate for you to investigate further: * Mon Dec 21 2009 Jarod Wilson <jarod@xxxxxxxxxx> [2.6.18-183.el5] - [sound] alsa hda driver update for rhel5.5 (Jaroslav Kysela) [525390] I need to do some reading and learning first - any particular place or howto that would help? I've heard of mock and other rebuild environments but never taken the plunge as I can normally wait for things to arrive in due course when upstream decides its ready to support it e.g. firefox, openoffice thunderbird etc. Or make use of Dags repo or elrepo. However regression is not something I can live with and unfortunately it seems to be becoming an issue. Thanks for the suggestion, I may try the ordinary kernel first (i.e. not centosplus kernel, just to be safe). _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos |
