They are much more different than i actually assumed. I'll try this test with Pardus to see what's our situation among the *popular* distros :) One of the fact of this huge difference between distributions is that a lot of popular distros don't prefer to ship alsa-driver as a separate package, leaving their alsa outdated in case of a lack of interest/time to backport the needed upstream changes. I'm trying to keep up with alsa upstream by being a little bit bleeding edge as we're shipping it as a separate package. > > Apparently OpenSUSE ships a kernel (2.6.27.7-9-pae) that causes > scheduling latencies of > 210ms.

Is that latency value obtained through your alsa-time-test or by another means like verbosed PA output?

Is there *really* any distribution around who doesn't enable preemption? The timer frequency can be a choice but not preempting the kernel is not sane nowadays. > > Thank you very much, Thanks for your interest. -- Ozan ?a?layan <ozan_at_pardus.org.tr>
