I have two F-16/64 bit computers that have sound problems. The
second one has no sound at all.
I can see sound moving the indicator trace in PA Volume Output
Devices but it does not get to ALSA.
PA sees no sound card at all, just a dummy. PA vol. configuration
has nothing to select.
Neither computer had a sound problem with F-15.
My problems appear to be similar to those of Patrick Dupre.
Alsamixer shows the sound card as "HDA Intel" but it is not "seen"
by PA.
HDA Intel is a generic name for the type of card, sort of like tissue
is generic, whereas Kleenex says it is manufactured by a specific
corp. aplay -lv will tell you that corp name and model, and the alsa
driver name.
blacklist.conf is:
No problems here.
Suggestions?
If you type, in a console, aplay some.wav , do you hear sound?
You have to replace some.wav with an actual wav file, but this sends
sound directly to alsa, and should work on both your machines.
[bobg@box9 ~]$ aplay -lv
aplay: device_list:240: no soundcards found...
I usually test sound with:
[bobg@box9 ~]$ aplay /usr/share/sounds/purple/login.wav
Playing WAVE '/usr/share/sounds/purple/login.wav' : Signed 16
bit Little Endian, Rate 22050 Hz, Stereo
However in this case no audible sound is produced.
Also as was suggested in the past I can run "pacmd info" and see the following:

I'm not sure how to interpret this but there's that "Dummy Output"
again!
So alsa is recognizing your card but PA isn't able to use it. Do you
have alsa-plugins-pulseaudio installed. That sets alsa to use PA as its
dafault output mode.
"alsa-plugins-pulseaudio" removed and reinstalled using Yumex as a
matter of convenience.
You could try reinstalling PA to see if it will correct the sound
configuration (or uninstalling and then installing again).
Perhaps re-installing PA will help, but I'll wait 'til later to try
that, it was three in the morning here and I just got up wanting a
cup of coffee. I think I'll see if there is any response to this
data first.
Beyond that, you need someone knowledgeable in PA, and that isn't me.
I thank you for your help.
