Can you clarify which sound device you're trying to use (the topic says HDMI, but then you mention headphone jack)?
If you're trying to use the HDMI audio, you should add "radeon.audio=1" to your kernel boot line in /etc/default/grub (and then run sudo update- grub). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074803 Title: [, ATI R6xx HDMI, Digital Out, HDMI] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1074803/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
