I experienced the same problem a few weeks before. With every reboot my soundcards (2xpci) changed position randomly.
As proposed also in Bug #8107, I edited /etc/modutils/alsa-base and changed my second soundcard to options snd-<your driver> index=-2 # Make sure it isn't the first card. If that does solve your problem to, I recommend marking this bug as a duplicate to #8107. -- Default soundcard changed on hard poweroff https://bugs.launchpad.net/bugs/113799 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
