I had "hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj." in my dmesg.
So I knew had to increase "bdl_pos_adj" for my second sound card (Nvidia HDMI). Added: options snd-hda-intel enable_msi=1 bdl_pos_adj=1,48 to my /etc/modprobe.d/alsa-base.conf After this tweak, both the warning message and the terrible crackling sound 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/267913 Title: hda-intel: IRQ timing workaround is activated for card #0.
