I installed Macromedia, mplayer, vlc. I tried to watch

System -> Preferences -> Personal -> volume control

I now do not hear sound when I select
System -> Administration -> Soundcard detection.

What could explain the soundcard not being detected?

Should I reinstall Fedora 7?

I sent an email out on Monday, 20th Aug to which noone
has responded. Are people tired of helping people get
sound working? Is the subject of no interest?

If anyone can give advice or feedback, I would appreciate
it. Can someone point me to documentation?

Thank you for your attention and consideration,

Darlene Wallach

See if your sound card has been detected.
aplay some.wav    this will use the default device
aplay -D plughw:0,0 some.wav  uses a different plugin than default

You can also look at aplay -lLv to see the info alsa has about your 
card and how it has configured it.
There is lots of information in /proc/asound as well.

By default alsa starts with sound muted, so use either the alsa 
mixer gui
or alsamixer in a terminal to adjust at least the master sound level.

If you have more than one soundcard, it is possible that they were 
assigned in a different order than you expect.  This requires 
explicit assignment it /etc/modprobe.conf.  Lately, I've noticed 
this occurring by default.

Some applications need to be configured to use the card.

And yes,  this question has been asked and answered many times on 
the list.  The answer has to be out there somewhere on the web, for 
sure on either the alsa-user list or this list at gmane.org.
I'm sure you find the subject of interest. :-)

I've had pretty good luck with sound, the basic functions have just 
worked.  If you are using an obscure chip, or a troublesome chip it 
can be problematic.  And because every sound card is different, 
only someone familiar with your card can really go beyond the basic 
stuff above.  For those, the alsa lists are probably the best bet.  
They can also tell you if it is even supported.

I did check all the email on the Fedora list regarding
sound problems with Fedora 7. What I did not see was
someone asking about sound working on the sound test
during installation and after installation, then the
sound test failing.

I do not understand what to do change on alsamixer either
the cli or the gui to try to get sound working again.

I tried aplay on a .au file and heard nothing.

I don't know what to put in google to even get close to
getting results that will be useful.

I am very frustrated with myself for somehow screwing up
sound that once worked.

Darlene Wallach

If it once worked, it will work again.  That is a positive.
What kind of card is it?

Does aplay -lLv show any output, or does it say 'no sound device 
detected'?

Or, equivalently, when you look in /proc/asound do you see 
information?  Does it exist?

If you don't see either of the above, your sound card is not 
detected.   Do the dmesg below to find out why.

If there is a card, do this.
Open a terminal.  Type alsamixer.
You will be on the master volume control.  Push the up arrow until it 
is at a reasonable height, just below the red or just in the red.  
Press escape.

Now try your sound again.

Do a "dmesg | grep -i snd"
and a "dmesg | grep -i alsa"

If your sound is not installing, there will be messages indicating 
errors in the output.
Please post those errors.

I used alsamixer and reduced the master and master m

I used wget to download

$ aplay -t au english.au
Playing Sparc Audio 'english.au' : Mu-Law, Rate 8000 Hz, Mono

I did not hear anything

# dmesg | grep -i snd
returns nothing

# dmesg | grep -i alsa
returns nothing

btw, I posted most of this and alot more in my original
message dated Monday, 20th August:
subject: sound prob Ensoniq ES1371 on Fedora 7

I pasted most of the contents of scsconfig.log.
I deleted parts I thought had nothing to do with
sound.

Thank you very much for responding to my email!

Darlene Wallach

You are very close to having sound.  Everything looks good, it is just a 
slight configuration issue. 

Try aplay -Dhw:0,0 your_sound_file
I think you should try to find a wav file if you can, I'm not sure that 
alsa converts formats.
If you don't have one, install audacity and convert a file you have to a 
wav.

Also check if you have oss installed.  There are programs out there that 
still use OSS instead of alsa.  Unless the alsa  oss emulation packages 
are installed, that won't work.

do yum list all | grep -i oss to find them.

if you have a .asoundrc in your home directory, move it to a backup.  Do 
the same with all the configuration files in /etc, /etc/asound.conf and 
/etc/asound.state (might be in /etc/alsa/asound.state).  Log in and out 
to refresh the configuration to the default for the card.

You do have speakers plugged in, right.  :-)

What does xmms do, (audio player).  If it complains, go into the options 
and select alsa as the device.
