I can confirm that the problem still exists in lucid final release and linux-alsa-driver-2.6.32-22-generic installed from the ppa:ubuntu-audio- dev.
The HDMI output does not work and the headphone output does not work. Plugging in the headphone causes the sound to turn off on the speakers but no output on the headphones.. Routing the sound to the HDMI from the sound prefs sliences the speakers but no output on the HDMI. The only reason there were no comments was because I was waiting for developer input. I had reported that the problem existed with 2.6..32.21 as well. ** Changed in: alsa-driver (Ubuntu) Status: Expired => New -- No sounds output through HDMI interface https://bugs.launchpad.net/bugs/567649 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
