No. 4: "LAP:~# cat /dev/urandom > /dev/audio" definitely gave me white
noise.
As for no. 5, I *think* what I have in the laptop is a CD-ROM drive
only. Regardless, I would not know how to differentiate a CD-ROM drive
from a DVD-ROM drive. The only external marking on the drive is the
word "disc" in large tip, with the word "compact" in small type over the
"isc" of the word "disc".
I find that strange, as the the CDROM drive was empty, nor could I see
any application open, except icedove and a terminal emulator.
Maybe audio device it's busy 'cause artsd it's locking it

ps: did you googled around for your 'sound card + kernel support'
Alsamixer identified the integrated sound card and chip as a Yamaha
OPL3-SA23. Earlier, when I ran alsaconf, first all the snd modules were
removed. Second, alsaconf found a card labeled "oplsa2 snd-oplsa2",
followed by "legacy Probe legacy ISA (non PnP) chips".
After selecting "OK" I was next presented with the following:
Configuring snd-opl3sa2
Do you want to modify /etc/modprobe.d/sound
(and /etc/modprobe.conf if present)?
I answered "Yes".
Next it said:
OK, sound driver is configured.
ALSA CONFIGURATOR will prepare the card for playing now.
Now I will load the ALSA sound driver and use amixer to raise the
default volumes.
You can change the volume later via a mixer.
After clicking "OK" once again, alsa told me the following:
Running update-modules...
Loading driver...
Setting default volumes...
===============================================================================
Now ALSA is ready to use.
For adjustment of volumes, use your favorite mixer.
Have a lot of fun!
As the return from "lsmod|grep snd" above seems to indicate, alsaconf
was as good as its word, having apparently installing all sorts of
modules unique to this card.
I did get the white noise as described above, and I do get through the
attached speakers some at least of the usual sounds which accompany
various actions, such as completion of a user log on, and a beep when in
a terminal I hit the down arrow key but there are no more commands in
that direction to show.
I googled this card and found information which was for the most part
way over my head but did tell me that this card is an ISA card and needs
to be tweaked to work. One of the web pages returned from the Google
search was part of the alsa howto:
http://www.alsa-project.org/alsa-doc/alsa-howto/x1298.htm.
It nevertheless appears to me that alsaconf did all the tweaking
necessary, as I have got some sound, but cannot play audio CDs or get
newscasts.
Another factor may or may not be relevant. Two days ago I compiled from
source and installed dosemu-1.3.4. The installation was successful in
that it is allowing me to use my beloved dos based applications.
However, the last message returned by ./configure was a warning that SDL
version 1.2.0 was not found.
I consequently installed four packages which had sdl in the name:
libsdl1.2debian, libsdl1.2debian-alsa, libsdl-net1.2 and
libsdl-sound1.2. I tried to purge these packages, but aptitude wanted
to remove a whole series of other packages including grub and icedove.
So I did not remove them. I also tried to remove them using Kpackage,
but Kpackage wanted to remove all of kde. So these four sdl packages
remain installed. (Why do aptitude and Kpackage want to remove
different apparent dependencies?)
If these packages are screwing up the sound, then a little knowledge on
my part is dangerous. I should have asked whether that warning message
could safely be ignored. Since I do not use the sound properties of
dosemu perhaps I should have left well enough alone.
