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.
