Just to make a follow up: I just found in http://lucasromerodb.blogspot.mx/2012/04/sin-salida-de-sonido-hdmi-en-ubuntu-ati.html something that works for this system: 1.Do $ gksu gedit /etc/default/grub
2.find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" 3. change to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" 4. do $ sudo update-grub 5. Reboot In this system (lspci gives Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series]), past versions of Ubuntu worked just fine, so I was confident that a solution was somewhere. However, this solution is not something that a complete newbie could do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989671 Title: [System Product Name, ATI RS690/780 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/989671/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
