Correction: all application tests I did, i.e. cat/aplay etc., apparently involved extensive buffering. This was pointed out to me on the alsa mailing list. I was advised to try arecord/aplay with the --buffer-size option, and tests with values up to 512 exhibited hardly noticable to very little lag. Especially, the gnomemeeting lags which initially made me investigate the whole situation then must happen on application and not on kernel/driver level. To restate the original problem: with gnomemeeting <-> netmeeting connections on LAN I get noticably more lag when voice is going gnomemeeting -> netmeeting than in the opposite direction, that lag amounting to about one to two seconds. According to gnomemeeting irc this seems to be way to much delay. I'll now try to optimize gnomemeeting settings, and depending on the outcome this whole issue may well turn out not to be a bug. In the meantime, I set the report status to NEEDINFO and will hopefully come back with a success report in a couple of days. An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you. This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you. |
