But some codecs (at least AD1986A) may give a zero NID in the middle of the connection list, so dropping the whole list isn't good for such cases. https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=d94ddd85b1e044c030d62c62f95ae700776888f8 ALSA: hda - Increase the max depth of widget connections Old codecs like AD1986A tend to have long paths as they were just made to be the way like AC97. The current max depth 5 can be too short for such devices. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1168736 Title: Crash in Firefox P5L-MX, Analog Devices AD1986A, Green Line Out, Rear No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1168736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
