No audio from HDMI output

Moderator note: This is not similar to the topic this post was attached to (which was about PulseAudio freezing or playing audibly fast) so a new topic with relevant subject was created.

Hi,
iam using alsa with pulse audio-1.0.25 and iam using ATI radeon E4690 graphics card with standard Fedora -17 os.
when iam trying to play audio with alsa, its not playing anything and coming out quickly. iam passing radeon.audio=1 as bootargument.
But my card is getting detected when iam giving the commands as below.

>>>>aplay -l

But when iam playing the music its showing like

Do you have a standard analogue motherboard audio output, or have you disabled it for some reason?

What is physically connected to the HDMI output?

Installing PulseAudio Volume Control (pavucontrol) can often sort out problems.

Try connecting speakers or headphones to the DAC and unmute its output in pavucontrol.

If you use the (hw) device for output instead of pulse, unmute the DAC output in ALSAmixer.

You can probably get more help if necessary on the Fedora forums http://fedoraforum.org/.

This question appears to be about configuring your hardware to work on Fedora rather than about Audacity. You may do better to ask on the Fedora forum as none of the regular contributors here use Fedora.
