I played a bit with power_profile settings and it turns our that whenever profile is set to high, mid, sound stuttering is pronounced. Yet, once set to low, stuttering is gone (or unnoticeable). If anyone wants to try (adjust path to suit your hardware): echo low > /sys/class/drm/card0/device/power_profile Then the actual frequency can be verified by: cat /sys/kernel/debug/dri/0/radeon_pm_info
Also dynpm power_method does not really work, there was another bug report recenty that the frequency is never lowered if dynpm is used. Additionally, given the recent fuss about pcie_aspm=force (and possible effect on PCIe), sound stuttering is present regardless of the setting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/564376 Title: Lucid - radeon kms causes iwl3945 to drop connection on youtube but not with mainline To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/564376/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
