apologies for starting yet another thread on this subject but i've searched through all the previous posts, and generally on the internet, and cannot find a solution. before i tear what little hair i have out, i am just hoping someone can help me.
i have an acer 6935g running a minimal installation of fc16, plus a few apps (it's basically running as a server).eg. these are the only pulse and also packages installed :
pulseaudio-libs-0.9.23-1.fc16.i686
pulseaudio-libs-0.9.23-1.fc16.x86_64
pulseaudio-libs-glib2-0.9.23-1.fc16.x86_64
alsa-lib-1.0.24-2.fc15.i686
alsa-lib-1.0.24-2.fc15.x86_64
alsa-utils-1.0.24.1-5.fc16.x86_64

i can include the full alsa-info.txt data if required.
i have tried making the various suggested changes to /etc/asound.conf and /etc/modprobe.d/dist-alsa.conf.
all playback via the "ALC889 Analog" device works fine.
when it comes to playback via the "HDMI 0" device, ithe following two commands run but there is no sound :
aplay -Dplug:hdmi {wav file}
aplay -Dplughw:0,3 {wav file}
i booted the same laptop to the fc16 live usb and this also had the same issue.
i booted the same laptop into windows vista and hdmi audio works fine.
can anyone make any suggestions as to what the problem is and what can be done to resolve this ?
many thanks in advance.
