I don't know whether this is the same bug, for I'm running 32 bit Karmic on a socket 775 EVGA motherboard. No sound through HDMI though lspci picks up Radion HD sound card (and also on-board intel sound). Cannot run sound preferences because hangs. Alsamixer error (aplay command) messages that searching for end of file and that asoundrc may be corrupted though reloading alsa and alsa-utils say fully updated, as is radionhd driver, which also shows as first suggested in xorg.conf file.
Unfortunately, Renato Campus' temp solution above doesn't work for me. Instead it produces the following: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/j/.gvfs Output information may be incomplete. lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/j/.gvfs Output information may be incomplete. -- [karmic] Radeon HD/RS780 Azalia - No HDMI sound by default https://bugs.launchpad.net/bugs/412688 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
