There's no such thing, that I know of, as 'kill hanging files'.  'lsof'
will give you process id's (PID values) with lots of other info, unless
-t is used, which is just the list of PID values.

You then use the PID values to kill the processes.


Indeed I wrote about "pipe" to a kill command.


So far as I can determine, neither 'kill' nor 'killall' accept input 
from stdin, just the command line.  A point I failed to notice in the 
earlier posts.




When a process dies, all its open files are closed, either by itself or
by the system on its behalf.  This is true even if 'kill -9' is used,
the system takes cleanup on exit very seriously.


Clear, but what happens when an application crashes? Did the 
system/process acts as said before?


No difference.  Any abnormal command exit that doesn't let the command 
clean up, the system will at least close the files.  It is impossible 
(on *NIX type systems) to have an open file without an associated 
process.  If the process goes away, the file closes.  Period.




The net result is that open files go away, and the filesystem is no
longer 'busy' and can be umount'ed.


Shall we start a new thread? :)


'nough said, I think, so no.

Really don't know, my rule is "the one which fits to your needs". I 
always use killall and feel comfortable with. Sometimes I use kill, e.g. 
when killing a process is not enough and some files are showed to be 
open by lsof after a killall or a kill -9.

Re: Sound on Linux?

[Raffaele Morelli]

In view the fact that the first thing everybody advised me to do was to
disable artsd.  On examination I found out that artsd is a KDE creation
which wants to monopolize all sound operations to the exclusion of all
others, even others part of the KDE empire, such as KsCD and Kaffeine.



noatun and kaffeine use artsd if kde is asked to run it as sound deamon.

It was then a simple matter to disable artsd as suggested by Nigel Henry

  (NH) by unchecking the "Enable the sound system" box in KDE's control
centre/Sound and Multimedia/Sound system.  For good measure I ran as
suggested by ASW "killall artsd", which produced a null return.

Also, as suggested by NH, I ran "cat /proc/asound/cards", which returned
the following:

  0 [OPL3SA23   ]: OPL3SA2 - Yamaha OPL3-SA23
   Yamaha OPL3-SA23 at 0x538, irq 5, dma 1&0

(Yes, Raffaele Morelli, I do need to educate myself about killing
processes as you suggested.  Hitherto I have never felt the need to kill
anything but pesky insects.  That exercise is however for another time.)



As being far away to be a geek but still far away to be lazy , I always feel
the need to educate myself too.

Then, as previously suggested by ASW, I ran "aplay

/usr/share/sounds/alsa/*.wav".  Lo and behold, I was greeted with a
series of words: "front and centre", "keep right", and several others in
the same vein.



Try cat /dev/urandom | aplay

I was then given five options: open in a new window, extract and encode

audio tracks, play, play CD with Kaffeine and do nothing.  I first chose
the simplest, play, which I discovered opened the KsCD window.  However,
I was unable to play.  (Before I made all the changes described above, I
had tried to use noatun, with the same result.)  So, I closed the KsCD
window, went back to the Audio CD KDE daemon window, chose "do nothing"
and closed that window.  I was then able to eject the disk.

I then reinserted the Audio CD.  When in due course I got the Audio CD
KDE daemon I chose the Kaffeine option.  To my shock and amazement the
CD started to play.  The sound was also accompanied by fireworks, sun
spots and similar kaleidoscopic visuals on the screen.  I am sure the
additional memory required for these inhibited the smooth functioning of
the audio, as there were frequent short gaps in the audio continuity.



In my experience Kaffeine and noatun are far to be a good players, install
xmms, is a full featured and best player I saw around.
If you look for essential, alsaplayer is the one for you.

I then tried a telecast using Kaffeine.  I got the audio but not the video.


The major lesson I have drawn from this experience it that there is a
plethora of audio (and video?) applications vying for the custom of my
laptop.  One in particular (arts) seems to have the power to exclude all
the others, but then misuses this power by denying any audio (and
video?) at all.

I consequently wonder whether any other sound application is
sufficiently powerful to exclude all others, such as KsCD and noatun,
but not Kaffeine.  It was with this possibility in view I included the
following two paragraphs two posts ago:



You don't need such application, you need to prevent artsd from running,
exluding it from kde or removing it and you did it.
Now I think you're facing only a configuration problem and that dosemu is
innocent.

Re: Sound on Linux?

[Raffaele Morelli]

If you are getting sound from that card using the cat, then I'm not
sure you need the isa stuff as the card is working and the kernel is
sending sound to it.



Ken pointed to alsa site, where it is said that without an isa-pnp module
the cards won't get properly configured.
http://www.alsa-project.org/alsa-doc/alsa-howto/x1298.htm

I suspect the problem is, as mentioned previously, artsd is getting in

the way. Your sound apps may be efaulting to alsa output with artsd
running and that causes a conflict.



artsd running prevents other applications to use alsa, but kaffeine and
noatun are kde stuffs, so they should play without alsa and artsd running.
(eg. xine can play audio tracks using artsd)

So, please try the above and report back.

I've spent some time looking into this today, but my Debian installs are on 
the other machine, and the sound card is an Audigy2 soundblaster, which is 
capable of multiple audio streams, so I've been looking at the problem on my 
FC2 install, with an earlier version of KDE.

First regarding SDL. I installed the relevant SDL packages on FC2 so I could 
play an SDL based game, and I've just looked on Debian Etch, and have 
installed it also on there for some reason or other.  The packages installed 
are.
libsdl-image1.2
libsdl-mixer1.2
libsdl-ttf2.0-0
libsdl1.2debian
libsdl1.2debian-oss
I have the alsa-oss package installed, so the above package doesn't create any 
problems, as the alsa-oss package provides an Alsa emulation layer to apps 
that need to use OSS.

I do not have libsdl-sound1.2, or libsdl-net1.2 installed.

I can't remember why I installed the SDL stuff. That was when my Etch was 
still Sarge, and is probably for some audio app that I installed.

I don't believe there is any problem in leaving those SDL libraries installed, 
as they should only be called on when you run an app that requires them.

btw. Is dosemu working for you?

It's worth installing the alsa-oss package, as if you have any OSS audio apps 
that you want to use, they will then work.

Getting back to KDE, aRts, and Noatun.

Noatun will play a .ogg music file irrespective of whether the check box in 
Controlcentre/sound and multimedia/sound system is checked or not.
Now I do have a one liner in a file named .asoundrc in /home user, and it 
doesn't matter now if that check box is checked or not. I can play a tune 
using Noatun, and play another tune using MhWaveedit at the same time.

The one liner is below with instructions.

Noatun, and playing cd's. I didn't know it could do that. Anyway, when I put a 
CD in the drive on Etch, I get a bit of activity showing on the drive, but 
nothing on the desktop. I then open cdplayer, and the CD is showing there 
with the title of the CD. Then pressing play, just plays the CD. I have seen 
this sort of multiple choice thing when inserting a CD on Fedora Core 5 
though. Btw. I don't though have kaffeine installed, so perhaps it behaves 
differently then.

Another thing to look at is /etc/group , and see if you as user are on the 
cdrom group. IIRC I put myself on that, as before doing so I could only play 
CD's when logged into the desktop as root.

Here's the one liner.

First create a file in your /home/user directory named .asoundrc . Then add 
the following line to the file, highlight, and paste, whatever.

pcm.dsp0 {  type plug  slave.pcm "dmix" }

Save it, and close the file. Seriously I don't know if this will fix any of 
your problems, but now I can have the checkbox in KDE's control centre/sound 
and multimedia/soundsystem checked without causing problems with other music 
apps.

Can't think of much more to say at the moment.

Nigel.

Re: Sound on Linux?

[Jorge Peixoto de Morais Neto]

I haven't even read this entire (huge) thread, but it seems strange to me
that KDE applications don't work with arts.

Can it be that the apps are misconfigured to use ALSA directly but you are
running arts? You should either:

1)Leave arts on with application set up to use it
or
2)Set applications to use ALSA directly and turn off arts.

I have heard somewhere that it is possible to use at the same time arts and
applications that use ALSA directly if you use something called dmix or
something like that.

Anyway, what I mean is, if you are having this problem than I think that
your apps are set up to use ALSA directly, and it should be possible to set
them up to use arts.

You can disable it in KDE's control centre/Sound and Multimedia/Sound system. 
Just uncheck the "Enable the sound system" box, then apply.

Most soundcards are not capable of multiple audio streams, and the aRts sound 
server is a prime candidate for causing problems, as it grabs the soundcard, 
then other sound apps won't work.

The last thing you want is having multiple problems preventing the sound from 
working.

You might also check.
cat /proc/asound/cards   to see if the card is actually showing up as card0.

no isa-pnp module to load...
... I think you need some isa related tool to deal with this card or an isa
capable kernel, i.e. recompile with isa support flag turned on.
I don't want to mislead you but I would go this way.

ah...
I read from this page:
This module does not support auto probe (if ISA PnP is not used) thus

Not 100% sure, but probably isa-pnp kernel module is needed for this 
card to be properly configured.

grep isa-pnp /etc/modules

if #isa-pnp line appears I suggest you to uncomment it and reboot.


No isa-pnp line in /etc/modules.

so your card is alive ;)

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".

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.



beeps depend on pcspkr kernel module, and they are not related to sound
card.

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.

If you did this from within X (or with X running), shut down X
completely and try again.

as mentioned elsewhere, double check alsamixer and make sure the
channels are not muted. of course, check the obvious -- speakers
turned up etc.

no need to mount the cd to play it. 

I suggest a couple things. 
1) send us the output of 

 lspci -vv | grep -A 10 Audio

and 

 lsmod | grep snd

2) try using a command line player on a wav file and see what
   happens. try this:

 aplay /usr/share/sounds/alsa/*.wav

this should play 9 files for different surround sound speakers, but
you should get something. if it works, then we can move on to the cd
and other issues. If it doesn't work, then send us the output.

Not sure if you have check this before, but have you verified you have 
proper volume settings on all your audio channels? Run alsamixer in a 
terminal, you will get a text based graphic display of the levels. Make 
sure none of the outputs are zero or muted. Up/Down arrows change the 
levels, "M" mutes/unmutes, and Left/Right change the channel.

If adduser is called with the 'add_extra_groups' (I mistakenly used
hyphens in my original message) option, then the new user is added even
if 'ADD_EXTRA_GROUPS' is left at the default and 'adduser.conf' is not
modified.

To be perfectly honest, I didn't know it either. I just knew that my
main user was in a bunch of groups and then I saw that my second user
wasn't, so I checked the man page for 'adduser' and searched for
'groups' ...

on sarge, however:
$ grep EXTRA /etc/adduser.conf
returns nothing;

on etch, however:
#EXTRA_GROUPS="dialout cdrom floppy audio src video lp src users"
# If ADD_EXTRA_GROUPS is set to something non-zero, the EXTRA_GROUPS
#ADD_EXTRA_GROUPS=1
#EXTRA_GROUPS="dialout cdrom floppy audio src video lp users"

The default groups to which new users are added (when created with
'adduser --add-extra-groups') is specified in '/etc/adduser.conf' by
the line beginning 'EXTRA_GROUPS'; the default does include 'audio'. On
my Sid system, the (non-root) user that I created during install
belongs to all those groups, but a user that I created subsequently
isn't, presumably because the installer used the '--add-extra-groups'
option and I didn't.

you should also add the user to the group audio (and video ?).



Yes, user must be in group 'audio' but I never did it manually...
Are you sure about the need of manual adds?
Or some post/pre installation scripts takes care about that?

2007/3/15, Ken Heard <[EMAIL PROTECTED]>:


I have always known that sound was available on Linux.  When I first
used Linux RH8 with KDE in a P4 box, I did not have sound on
installation in July 2003.  At the time it was all I could do to get
working what I really needed; sound was not a priority.  I did not
really miss it because I still had a laptop with Win98 which I could and
did use on the rare occasions when I would want sound.

Early in 2006 when Sarge was released I installed it with KDE on that P4
box, but sound was still not operational.  I still had that laptop to
use for those rare sound occasions.

In January 2007 I installed Etch with KDE on that laptop, but still have
no sound.  Now however I have no Win98 to fall back on.  As I will be
away from home for the entire month of March I would like sound but
still do not have it.

I have in the past three days tried to do two things which require
sound: play an audio CD and listen to a telecast.  It the former case I
tried to use KDE's noatun and in the latter Icedove with Kaffeine
installed.  In both cases, the only result I got when I hit the play or
start button was the KDE crash handler showing information I did not
understand.

Other than the foregoing I don't know what else to say.  I am truly in a
position where that is the best I can do to describe my results when I
try to use sound.  Put another way, I do not know what questions to ask.

The only thing I can think of is that I am missing one or more packages,
but which?  I do not even know what packages are necessary for sound.  I
would appreciate if one or more of the experts out there could give me
some clues as to what I should be looking for.



You miss alsa* packages, they are the only thing you need.
Just have a look to discover output to investigate if your laptop ships a
somewhat "strange" soundcard model.

For complex tasks you may want to install jack audio server too.

the alsa packages are needed.
IIRC alsa-base,alsa-tools,alsa-utils.
the run as root:
alsaconf
and it should do the rest.
