Found a better fix. Added: options snd-hda-intel enable_msi=1 bdl_pos_adj=1,48
to /etc/modprobe.d/alsa-base.conf Explanation: I had "hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj." in my dmesg. So I had to increase "bdl_pos_adj" for my second sound card (Nvidia HDMI). After this tweak, both the message and the crackling are gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1029414 Title: Audio problems with ALSA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1029414/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
