Thread: No sound via HDMI AMD Radeon HD 7670 Ubuntu 13.04 64bit

-

i did fresh install of ubuntu 13.04 64bit , able play sound via hdmi using open source drivers. problem there no hardware acceleration via drivers , make fan spin if left idle hours. amd graphics drivers have installed version 13.4 amd legacy driver. have edited kernel parameters like:

grub_cmdline_linux_default="quiet splash"

, changed to:

grub_cmdline_linux_default="quiet splash radeon.audio=1" (this method worked open source drivers not closed source drivers)

appreciated

please provide hw info. @ minimum, do:
code:
lspci -vk | egrep -ia13 "vga|audio"
your boot parameter won't work because radeon.audio parameter specific open-source radeon driver whereas have closed-source fglrx installed. sound being piped through motherboard sound chip instead of video card, impossible know without proper hw info.

a week ago in premiere pro cs6 world. one day updated windows, next day few .mp4 video files opened in premiere pro, played fine well, except fact display has green (sometimes multicolour, solid green block) bars in lower third of screen. see screenshot below.   these same files open/display fine in after effects, photoshop , vlc- , quicktime players. i'd read fromyears ago windows updates causing this, removed 1 of therecent kb's no avail. i did install adobemediaencodertrial_64-6.0.3-mul-adobeupdate and dynamiclinkmediaserverretail-1.0.1-mul-adobeupdate and reverted quicktime 7.6 but nothing makes difference.   in end, formatted c:\, reinstalled windows 7 ultimate 64bit , downloaded/installed 260 updates , reinstalled cs6 (and aforementioned ame , dlms updates , qt7.6) it's still same problem.   also tried exporting (part of) 1 of these files, see if wasn't display problem: exported file same properties original has green bars.   what else can do?   thanks in advanc
