Hi All,

It seems that when Amarok is playing, all system sounds are put on hold.  Once 
I close Amarok then all system (KDE) notifications suddenly sound at once!

How do I figure out what's wrong and how should I fix it?

One word:

arts

It's an abomination that should not be suffered to live. Disable it, 
switch it off, consign it to hell for all eternity. 

The only reason arts even exists at all is that in days gone by the 
hardware could not mix several signals into one by itself, so sound 
servers were written to do this then present one big sound stream to 
alsa. These days alsa does the job by itself without needing arts.

You can also compile all of kde switching off the "alsa" use flag.

Did you mean to say "arts"?  I thought that this was required to be able to 
play KDE system notifications?

I checked again my settings.  I have enabled the Sound System in Kcontrol, but 
have set it to use alsa.  However, under System Notifications I used to 
have /usr/bin/aplay as the external sound player (under Audio Player 
settings).  Since aplay was hard masked a long time ago, I switched back 
to 'KDE sound system' which I believe is using Arts.  I recall dmix playing 
nicely with arts by mixing system notification sounds with alsa.  From your 
messages I assume that although alsa deals with software mixing all on its 
own it does not mix in nicely with Arts.

Since aplay is hard masked, what external player should I use?  What other 
options are there to be able to play system notifications, if I want to keep 
alsa?

Thanks for your responses.

no, arts is not required to be able to play the KDE notifications.

In all fairness it used to be necessary to enable arts for kdelibs...

How am I supposed to specify sox?  /usr/bin/sox doesn't play any sound.  :(

Have a look at this "Do I really need aRts?" thread, in the middle it 
says:

 "now, copy this script into /usr/bin/Ksplay: 

   #! /bin/sh 
   sox "$@" -v 1.0 -q -t alsa default & 
 
  emerge sox to get an external sound player for 
  kdm events. Go into the control center, click
  system notifications and click "player settings"
  near the bottom. Click "use external player"
  and then type /usr/bin/Ksplay.

Alternatively you can just use the script "/usr/bin/play", included in
the sox package.

Cool! I seem to have missed this in man sox.  It plays system sounds now 
nicely.

Thank you for your help.

Blast! I spoke too soon.  It /usr/bin/play plays system sounds fine, by alsa 
will not mix them if e.g. amarok is playing in the background.  It's either 
one or the other.  Do I need to rebuild kdelibs without arts for it to work?  
This should really be simpler.

Do you have an alsa configuration file (e.g. /etc/asoundrc)?  I used dmix a 
while back, and when it changed to being the default, my asoundrc broke 
playback.  You might try deleting (or at least removing any dmix/dsnoop 
entries from) that file.

Thanks Bo,

Actually, I do not have an /etc/asoundrc.  I used to have ~/.asoundrc which I 
moved to #/.asoundrc_OLD back then, when elog told me to do so.  Subsequent 
updates did not recreate it - so I assume it is not needed anymore?

i recently went through this after something broke in arts. I turned off the 
KDE sound system and in the System Notifications dialog, 
specified "playsound" as the external player (found in sdl-sound package). 
You can also use "mplayer" but the module is enormous. Everything works 
really well now, with no drop-outs during the KDE Start/Stop fan-fares. :)

aplay is not masked, it is part of alsa-utils.

Oops, you're right.  I am (almost) sure it had been hard masked some time in 
the past, I remember emerge --sync telling me all about it.  Anyway, it seems 
that playsound now works fine and I have added -arts to my USE flags.

While we're at it I might as well share this little sound problem/feature with 
you: 

When my laptop boots up the sound is always muted.  To kick start it I need to 
either increase/decrease the volume (Master, or PCM) using alsamixer, or 
press the dedicated volume hardware buttons on the laptop keyboard.  It can 
get more weird too:  If I have launched an application that uses sound 
directly like e.g. Amarok, then in addition I need to increase the volume to 
100% to get sound from both speakers.  Otherwise only the RH speaker works.  
Does this all make any sense to you?
