Is there already a sustainable fix for this issue? I have the same problem on my "HP EliteBook 840 G1". I'm running "ubuntu-14.04.1-desktop-amd64". Every time when I open the System Settings my computer respective my mouse freezes for 1-2 seconds. And when I try to play a video with totem player then after 10-20 seconds the sound disappears and VLC does not play any sound but complains: "Audio output failed: The audio device "default" could not be used. Connection refused." In my kern.log - I get the following logs (similar log entries I get in "syslog"): ...

As described above appended the following entry: ... options snd-hda-intel enable=0,1,0 ... at the end of the existing file "/etc/modprobe.d/alsa-base.conf" This works for now but I wonder whether this is the final solution to this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310260 Title: Pulseaudio fails to detect card (probably due to hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1310260/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
