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
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]

But when iam playing the music its showing like

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE ‘/usr/share/sounds/alsa/Front_Center.wav’ : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

its looking like playing but its coming out very quickly and nothing is audible.

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.

hi,
HDMI output is connected to DAC and audio codec. ya i have motherboard audio output which i have disabled.

4

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.
