Hello Anthony, This issue still exist even tested with the latest oem-audio-hda-daily-dkms - 0.201411191501~ubuntu14.04.1 from the PPA .
However, I found out that this issue is identical to bug 1383997, the detection works with power source plugged. And adding the following entry into /etc/modprobe.d/alsa-base.conf could make it work without power source plugged: "options snd-hda-intel jackpoll_ms=500" Thanks -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer-updates in Ubuntu. https://bugs.launchpad.net/bugs/1379180 Title: AMD Radeon HD 8670A/8670M/8690M [1002:6660] No HDMI audio with open- source / proprietary driver To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1379180/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
