options snd-hda-intel enable=1,1,0 Re-enabled the Intel HDMI Device without breaking my speaker output however it does not bring back the actual HDMI Audio signal as that seems to be internally wired to the Radeon. I get a video signal through however so I don't quite know what's going on.
In addition my Notebook doesn't have a native HDMI port, only one DisplayPort output if that means anything. And as stated above this feature matrix lists DP Audio as TODO http://xorg.freedesktop.org/wiki/RadeonFeature/ so I don't know if this might be the root of the problem. I believe it has something to do with the GPU being deactivated without ALSA being aware of that. Should I file a bugreport for the radeon driver or should I contact one of the AMD developers via mail/irc to ask them to have a look at the existing one? "Vga-switcheroo cards are quite unusual" Well actually they are not as unusual as most hybrid laptops use this mechanism unless the NVIDIA / AMD blobs are installed. Installing fglrx solves the problem but gives me a very unpleasant experience (tearing, no seamless switching, etc...) So I would prefer to continue using the mesa drivers if possible. @Raymond: Could you give me the full xrandr command to try out? I'm not very experienced with xrandr with the exception of "--listproviders" and "--setprovideroffloadsink radeon Intel" Thanks, both of you! -- 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
